Answer:
any value other than 8
Step-by-step explanation:
If c = 8, the two sides of the equation say the same thing, so any value of x will satisfy the equation.
If c ≠ 8, there are no values of x that can make the equation true, hence no solutions.
There is no solution for any value of c that is not 8.
[tex]c=-3x+8+3x\\c=8[/tex]
If c = 8 then the solution is infinite. (because the equation is true)
[tex]-3x+7=-3x+8\\-3x+7+3x-8=0\\1=0[/tex]
If c < 8 then there're no solutions. (the equation is false)
[tex]-3x+9=-3x+8\\-3x+9+3x-8=0\\1=0[/tex]
If c > 8 then there're no solutions.
easy way. also if you look at the graph. It's literally impossible to have one intercept if the coefficient of x for both have the same operators and same absolute value like -2x+c = -2x + a or -3x+2 = -3x+5, we'll never get a single intercept. If we change like -3x+c = -5x+8, we might still get one solution.

Which represents where f(x) = g(x)?
•f(4) = g(4) and f(0) = g(0)
•f(-4) = g(-4) and f(0) = g(0)
•f(4) = 9(-2) and f(4) = g(4)
•f(0) = g(-4) and f(4) = g(-2)
Answer:
Option (1)
Step-by-step explanation:
Two functions 'f' and 'g' have been graphed in the picture attached.
Both the functions will be equal at the points where the values of these functions are equal.
Those points are the point of intersection of both the functions on the given graph.
At x = -4,
f(-4) = g(-4) = 4
At x = 0,
f(0) = g(0) = 4
Therefore, Option (1) will be the answer.

If two of these shapes are randomly chosen, one after the other without replacement, what is the probability that the first will be a triangle and the second will be a square?
Answer:
[tex]P(T\ n\ S) = \frac{1}{14}[/tex]
Step-by-step explanation:
*Missing Part of the Question*
4 stars
5 triangles
3 circles
3 squares
Required
Determine the probability of triangle being first then square being second
[tex]Total = 4 + 5 + 3 + 3[/tex]
[tex]Total = 15[/tex]
Represent the triangle with T and square with S
So, we're solving for P(T n S)
[tex]P(T\ n\ S) = P(T) * P(S)[/tex]
Solving for P(T)
[tex]P(T) = \frac{n(T)}{Total}[/tex]
[tex]P(T) = \frac{5}{15}[/tex]
Solving for P(S)
The question implies a probability without replacement;
Hence Total has now been reduced by 1
Total = 14
[tex]P(S) = \frac{n(S)}{Total}[/tex]
[tex]P(S) = \frac{3}{14}[/tex]
Recall that
[tex]P(T\ n\ S) = P(T) * P(S)[/tex]
[tex]P(T\ n\ S) = \frac{5}{15} * \frac{3}{14}[/tex]
[tex]P(T\ n\ S) = \frac{15}{15 * 14}[/tex]
[tex]P(T\ n\ S) = \frac{1}{14}[/tex]
Hence, the required probability is
[tex]P(T\ n\ S) = \frac{1}{14}[/tex]

Rachael gave a survey to her classmates to learn about their superstitions. Here's some of the data she collected.
can you answer the one in the picture and this question also please:
This data set contains:Choose 1 Answer:
A) 4 Variables, 1 of which is quantitative
B) 4 variables, 2 of which are quantitative
C) 3 variables, 1 of which is quantitative
D) 3 variables, 2 of which are quantitative
The individuals in this data set are B) Rachael's Classmates
The first column of the table is what will give this away
==========================================================
This data set contains A) 4 Variables, 1 of which is quantitative
Why is this? Because the four variables are
GenderAgeBirth monthRead horoscopeAge is quantitative because it deals with a quantity or number. We can do things like find the average age and it makes sense to do so. The other variables are qualitative or categorical. Gender is nominal as you can't order the data. Birth month is ordinal though because we can order the months from January to December. The responses for "read horoscope" are nominal data because we cannot order "yes" versus "no".

<=> x= 3 or x = 2
Trig is getting weirder? Which equation do I use?
How do I solve 4x-5=7+4y for y
Answer: Y= x-3
Step-by-step explanation:
Subtract 7 from both sides.
4x-5-7=4y
Simplify 4x-5-7 to 4x-12
4x-12=4y
Divide both sides by 4
4x-12/4 = y
Factor out the common term 4
4(x-3)/4 = y
Cancel 4
x-3=y
Switch sides
y=x-3

On average I sleep 7 hours and 45 minutes each day. Therefore, during one year I sleep for 7.45 x 365 = 2719.25 hours. Why is this calculation incorrect? And what is the correct answer?
Answer:
2830.6875 hours of sleep per year (7.45 should be 7.75)
Step-by-step explanation:
To find your average sleep per year, you need to covert avg hours per day, to days per year.
Note that 45 minutes is not equivalent to .45 hours, but actually .75 hours since there are only 60 minutes in an hour. ( 45 / 60 == .75 )
Simply, the amount of days per year is 365.25 (to account for leap years).
So perform this calculation:
(7.75 hrs / day ) * ( 365.25 days / year ) == 2830.6875 hrs / year
Meaning, on average you get 2830.6875 hours of sleep per year.
need help with both of these please!! ASAP

Answer:
[tex] m\angle XVW = 100\degree[/tex]
Step-by-step explanation:
In the first figure, FP is the bisector of [tex] \angle DFE[/tex]
[tex] \therefore m\angle 1 = m\angle 2\\
\therefore 44x + 1 = 46x - 1\\
\therefore 1 + 1 = 46x - 44x\\
\therefore 2 = 2x\\
\therefore \frac{2}{2} = x \\
\huge \red {\boxed {\therefore x = 1}} [/tex]
In the second figure, VP is the bisector of [tex] \angle XVW[/tex]
[tex] \therefore m\angle 1 = m\angle 2\\
\therefore 12x + 2 = 11x +6\\
\therefore 12x - 11x = 6 - 2\\
\therefore x = 4\\
\because m\angle XVW = m\angle1 + m\angle 2\\
\therefore m\angle XVW = 12x + 2 + 11x +6\\
\therefore m\angle XVW = 23x + 8\\
\therefore m\angle XVW = 23\times 4+ 8\\
\therefore m\angle XVW = 92+ 8\\
\huge \purple {\boxed {\therefore m\angle XVW = 100\degree}} \\

michelle is selling her condo. she needs to make at least $42,000 from the sale so she can make a down payment on a new house. if a 5.5% real estate commission is deducted, what is the lowest offer michelle should accept to get her down payment
Answer:
Minimum amount she needs = $44,444 (Approx)
Step-by-step explanation:
Given:
Down payment of house = $42,000
Real estate commission = 5.5%
Find:
Minimum amount she needs
Computation:
Minimum amount she needs = Down payment of house / (100% - Real estate commission)
Minimum amount she needs = [$42,000 / 94.5]100
Minimum amount she needs = $44,444 (Approx)

use the formula for the area of a trapezoid A=h(b1+b2/2), were area is A b1 and b2 are the length of the base and h is the hight of 15yd. and the bases of 14yd.and 26yd
Answer: 300 yards
Step-by-step explanation:
Since b1 is equal to 14 yds and b2 is equal to 26 yds we can plug that into the equation below (in the image).
b1 + b2 = 14 + 26 = 40 yards
Now that we have found (b1 + b2), you can multiply that by h (the height of the trapezoid) which is 15, so we get 40 x 15 = 600.
In a lot of area equations, you will have to divide by two like in the trapezoid equation. Divide our number (600) by 2, so we get 600 ÷ 2 = 300.
300 yds is your final answer.

On Monday, a restaurant made $545 by selling 110 hamburgers. If they sold 53 hamburgers on Tuesday. How much money did they make? (Round your answer) *
Answer: $263
Step-by-step explanation:
From the question, we are informed that Monday, a restaurant made $545 by selling 110 hamburgers. This means that one hamburger costs:
= $545/110
= $4.955
Therefore, 53 hamburgers will cost:
= 53 × $4.955
= $262.62
= $263 approximately

doesn't pass the vertical line test
Answer:
x=4
Step-by-step explanation:
Realize that a function can only have one output, y, for each unique input, x.
2 Methods on finding if something is a function or not.
Do the vertical function test
To use the vertical line test, take a ruler or other straight edge and draw a line parallel to the y-axis for any chosen value of x. If the vertical line you drew intersects the graph more than once for any value of x then the graph is not the graph of a function.
Plug in points! See if there are more than one outputs for y
a plane decides to travel along AB towards the North with a velocity of V.
Prove that the time taken to reach the destination due to the strong winds blowing from the north to east at an angle of alpha is
[tex] \frac{a}{ {v}^{2} - {w}^{2} } ( \sqrt{ {v}^{2} - {w}^{2} \ { \sin \ }^{2} \alpha } + w \cos( \alpha ) [/tex]
[using relative velocity /\ ]
Step-by-step explanation:
The wind has a speed of w and a direction α with the vertical. The x component of that speed is w sin α. The y component is -w cos α.
In order to stay on the north trajectory AB, the plane must have a horizontal speed of -w sin α. The plane's speed is v, so using Pythagorean theorem, the y component of the plane's speed is:
v² = (-w sin α)² + vᵧ²
v² = w² sin²α + vᵧ²
vᵧ = √(v² − w² sin²α)
The total vertical speed is therefore √(v² − w² sin²α) − w cos α.
If a is the length of AB, then the time is:
t = a / [√(v² − w² sin²α) − w cos α]
To rationalize the denominator, we multiply by the conjugate.
t = a / [√(v² − w² sin²α) − w cos α] × [√(v² − w² sin²α) + w cos α] / [√(v² − w² sin²α) + w cos α]
t = a [√(v² − w² sin²α) + w cos α] / (v² − w² sin²α − w² cos²α)
t = a [√(v² − w² sin²α) + w cos α] / (v² − w²)
Which of the numbers shown are
rational?
I.
TT
II. ✓49
III. 0.287
IV. ✓9/16
V.25
F I only
G II and III only
HII, III and IV only
J II, III, IV and V only
Answer:
The correct option is J.II, III, IV and V only.
Step-by-step explanation:
A rational number are those numbers that can shown in a p/q form or as the ratio of two numbers.
The numbers that cannot be shown as the ratio of two numbers are known as irrational.
Consider each number at a time:
[tex]\sqrt{49} =7\equiv 7:1[/tex]
[tex]0.287=\frac{287}{1000}[/tex]
[tex]\sqrt{\frac{9}{16}}=\frac{3}{4}\equiv 3:4[/tex]
[tex]25\equiv 25:1[/tex]
Thus, the numbers that are rational are II, III, IV and V.
The correct option is J.
