Answer:
(3,-3)
Step-by-step explanation:
First you divide 2 out of the first equation and it turns into 5x+y=12.
Then you write one on top of the other so you can add them. It looks like:
5x + y = 12
-5x + y = -18
Then you add them together and the 5x's cancel each other out and you are left with 2y = -6
So then you divide both sides by 2 and get y = -3
Then you plug -3 into the second equation because it is simpler and get -5x - 3 = -18
So then you add three to both sides and get -5x = -15
And finally you divide both sides by -5 and get x=3

A movie rental company offers a membership plan that costs $10/month and charges $2 to rent each movie. How many movies can a mentor rent in one month and spend at most $24? Write and solve the linear inquality..... Right Answer Will Be Crowned TYPE SOMETHING OTHER THAN THE ANSWER WILL GET DELETED! CORRECT ANSWER GET 50 POINTS
Answer:
See below
Step-by-step explanation:
linear equation: y=2x+10
x=cost per movie rented
10=$10 for the membership
24=2x+10 (24 being total you want to spend)
subtract 10 from each side
14=2x
divide by 2
7=x
He can rent no more than 7 movies if he want to spend $24 or less in the month

if the area of a rectangle is square meters, then the length is 10 meters and the width is 2 meters
━━━━━━━━━━━━━━━ ♡ ━━━━━━━━━━━━━━━
To find the area of a rectangle or square, you multiply the length by the height.
The length is 10 meters and the width is 2 meters.
10 times 2 is 20.
The rectangle is 20 square meters.
━━━━━━━━━━━━━━━ ♡ ━━━━━━━━━━━━━━━
The required area of the rectangle is 20 square meters.
Given that,
If a rectangle's area is square meters, then the length is 10 meters and the width is 2 meters.
The rectangle is 4 sided geometric shape whose opposites are equal in length and all angles are about 90°.
Here,
area of the rectangle is given as
Area = length × width
Area = 10 × 2
Area = 20
Thus, the area of the rectangle is 20 square meters.

Divide $700 in the ratio 5:3:2 (S
Answer:
350:210:140
Step-by-step explanation:
5+3+2=10, so we need 10 equal parts
700÷10=70
5x70=350
3x70=210
2x70=140
350:210:140
Answer:
Explanation: 5:3:2 means 5+ 3+ 2 = $10 is devided into $5,$3,$2. Therefore $700 is divided in ratio (5:3:2) as 700 10 ⋅5 = $350, 700 10 ⋅ 3 = $210 and 700 10 ⋅ 2 = $140

Answer:
[tex]\bold{2\cdot10^9}[/tex]
Step-by-step explanation:
The given expression s are:
[tex]8 \cdot 10^4[/tex] and
[tex]4\cdot10^{-5}[/tex]
To find:
[tex]8 \cdot 10^4[/tex] is how many times as large as [tex]4\cdot10^{-5}[/tex].
Solution:
Let [tex]8 \cdot 10^4[/tex] is [tex]x[/tex] times as large as [tex]4\cdot10^{-5}[/tex].
So, we can say that:
[tex]8 \cdot 10^4[/tex] = [tex]4\cdot10^{-5}[/tex][tex]\times[/tex] [tex]x[/tex]
OR
[tex]x= \dfrac{8\cdot 10^4}{4\cdot 10^{-5}}[/tex]
Let us have a look at the formula for exponents:
[tex]\dfrac{x^p}{x^q} = x^{p-q}[/tex]
Here we have:
[tex]x=10\\p=4\ and\\q=-5[/tex]
Solving the expression using above formula:
[tex]\Rightarrow x= \dfrac{8}{4}\cdot 10^{4-(-5)}} = \bold{2\cdot10^9}[/tex]
So, Let [tex]8 \cdot 10^4[/tex] is [tex]\bold{2\cdot10^9}[/tex] times as large as [tex]4\cdot10^{-5}[/tex]

find the slope of the line through (-4, 2) and (5,8) on a coordinate plane
Answer: m = 2/3
Step-by-step explanation: Use the slope formula to find the slope m.
: m = slope :
: slope of a line : m = rise/run = y2-y1/x2-x1 :
: (x1,y1) : coordinates of first point in the line :
: (x2,y2) : coordinates of second point in the line :
I hope this helps you out.
Answer:
Slope = 2 / 3
Step-by-step explanation:
Slope = (y2-y1) / (x2-x1)
y2 is the y coordinate of the second ordered pair and y1 is the y coordinate of the first ordered pair. x2 is the x coordinate of the second ordered pair and x1 is the x coordinate of the first ordered pair.
=(8-2) / (5+4)
= 6 / 9
Slope = 2 / 3
In the function f(x) = 4x -2, which of the following is the name of the function?
Answer:
The name of the function is linear function.
Step-by-step explanation:
A linear function is the function representing a straight line.
A linear function is used to define the relationship between a dependent variable and independent variable.
The general form of a linear function is:
y = m·x + c
Here,
y = dependent variable
x = independent variable
m = slope
c = intercept
The function provided is:
f (x) = 4·x - 2
The above function is similar to the linear function's general form.
The slope of the provided function is 4 and the intercept is -2.
Thus, the name of the function is linear function.
Help if you can please!!
===================================================
Work Shown:
c(b) = 5b
h(b) = b+4
h(c(b)) = c(b)+4 ... replace every b with c(b)
h(c(b)) = 5b+4 ... replace c(b) on the right hand side with 5b
For the sake of simplicity, let's call "h(c(b))" as k
k = h(c(b))
k = 5b+4
that way we can use it later in the next section
---------------
a(b) = b^2 + 7
a(k) = k^2 + 7 ... replace b with k
a(k) = (5b+4)^2 + 7 ... plug in k = 5b+4
a(k) = 25b^2+40b+16+7 .... use FOIL rule
a(k) = 25b^2+40b+23
a( h(c(b)) ) = 25b^2+40b+23
In that last step, I replaced k with h(c(b)) so that we get to the original format your teacher wanted.
These are my questions.

Two complementary angles are in the ratio 7:8. What is the measure of the larger angle?
Answer
48°Step-by-step explanation:
We know that sum of complementary angle adds to 90°
Let the angles be 7x and 8x
First of all, finding the value of x
[tex] \sf{7x + 8x = 90 °}[/tex]
Collect like terms
⇒[tex] \sf{15x = 90 °}[/tex]
Divide both sides of the equation by 15
⇒[tex] \sf{ \frac{15x}{15} = \frac{90}{15} }[/tex]
Calculate
⇒[tex] \sf{x = 6 °}[/tex]
The value of X is 6°
Now, substituting / Replacing the value of x
⇒[tex] \sf{7x = 7 \times 6 = 42}[/tex]
⇒[tex] \sf{8x = 8 \times 6 = 48}[/tex]
The measure of larger angle is 48°
Hope I helped!

What is the difference between a rational number and anirrational number?
Step-by-step explanation:
I'm sure u could've googled this answer.
Rational numbers refers to a number that can be expressed in a ratio of two integers.
An irrational number is one which can't be written as a ratio of two integers.
Rational numbers are the numbers which are integers and fractions
Irrational numbers are the numbers whose expression as a fraction is not possible
A farmer was dividing up his one-eighth of an acre of land between his 6 children. Since each child got the same amount of land, what fraction of the acre did each get?
Answer:
1/48
Step-by-step explanation:
A farmer was dividing up his one-eighth of an acre of land between his 6 children.
We are told each child got: the same amount of land. Hence,
1/8 of 1 acre =
1/8 acre of land
Divide 1/8 acre of land by 6 children
1/8 ÷ 6
1/8 × 1/6
= 1/48
Hence, the fraction of the acre of the land that each child got = 1/48
WY bisects UV at Y. If
UY = 2x +1 and YV = x+7, find
UV.
Answer:
3x + 8
Step-by-step explanation:
Since, WY bisects UV at Y.
Therefore,
UV = UY + YV
UV = 2x + 1 + x + 7
UV = 2x + x + 1 + 7
UV = 3x + 8
The measure of length UV given that UY = 2x +1 and YV = x+7 is 3x + 8
To bisect a given line means to divide the line into two equal parts.
If WY bisects UV at Y, then:
UY + YV = UV and UY = YV
Given the following parameters:
UY = 2x +1
YV = x+7
Required
UV
Substitute the given parameters into the formula shown above:
2x + 1 + x + 7 = UV
Collect the like terms
2x + x + 1 + 7 UV
3x + 8 = UV
Swap
UV = 3x + 8
Hence the measure of length UV is 3x + 8
