Answer:
y = -1.0
Step-by-step explanation:
Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operations, and =
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
First, add 4y and subtract 14 from both sides:
1y (+4y) + 14 (-14) = -4y (+4y) + 9 (-14)
1y + 4y = 9 - 14
Combine like terms:
5y = -5
Isolate the variable, y. Divide 5 from both sides:
(5y)/5 = (-5)/5
y = -5/5
y = -1
y = -1 is your answer.

Stacy sent 10 more texts than twice her little sister yesterday together they sent 46 texts how many texts did Tracy send
Answer:
Tracy sent 12 texts
Step-by-step explanation:
hope this helps
Answer:
The answer is 12 texts.
Step-by-step explanation:
Ok, so I'm assuming that Tracy is the little sister.
Stacy's texts: s
Tracy's texts: t
46 = s + t
s = 2t + 10
Substitute 2t + 10 for s in the first equation.
46 = 2t + 10 + t
46 = 3t + 10
-10 -10
36 = 3t
36/3 = 12
Tracy sent 12 texts and Stacy sent 34 texts.

[tex]x + 2y = -1\\x=-2,0,3\\f(x)=y\\[/tex]
plug in each value of x in the function y:
[tex]-2+2y=-1\\2y=1\\y=\frac{1}{2}[/tex]
first point is [tex](-2, \frac{1}{2})[/tex]
so when x = -2, f(x) = 1/2
[tex]0+2y=-1\\2y=-1\\y=-\frac{1}{2}[/tex]
second point is [tex](0,-\frac{1}{2})[/tex]
so when x = 0, f(x) = -1/2
[tex]3+2y=-1\\2y=-4\\y=-2[/tex]
third point is [tex](3,-2)[/tex]
so when x = 3, f(x) = -2
A hiker travels at 4 miles per hour at a heading of S 35° E from a ranger station. After 3
hours how far south and how far east is the hiker from the station?
Answer:
First, let's define our coordinates.
Let's call East as the positive x-axis and North as the positive y-axis.
Now the data that we have is:
Speed = 4 mph
Time = 3 hours.
Then the total distance traveled is:
D = 4mph*3h = 12 miles.
We also know that the angle is S 35° E.
(from east, 35° to south)
So we can write this angle as -35°.
Then if we want to know the component in South and East, we can first think this in polar coordinates
(R, θ)
where R = 12 miles, and θ = -35°
Now with this, we have that:
X = R*cos(θ) = the displacement to the east.
Y = R*sin(θ) = the displacement to the north (then -Y is the displacement to the south).
Then we have:
X = 12mi*cos(-35°) = 9.83mi
Y = 12mi*sin(-35°) = - 6.89 mi.
Then:
The displacement to the East is X = 9.83 miles
The displacement to the South is -Y = 6.89 miles.
The magnitude of southern displacement of the hiker is 6.88 miles.
The magnitude of eastern displacement of the hiker is 9.83 miles.
The given parameters;
Velocity of the hiker, v = 4 mphPosition of the hiker, θ = S 35⁰ ETime of motion, t = 3 hoursThe resultant displacement of the hiker is calculated as follows;
D = vt
D = 4 mph x 3 h
D = 12 miles
The magnitude of southern displacement of the hiker is calculated as follows;
[tex]D_y = D \times sin(\theta)\\\\D_y = 12 \ miles \times sin(35)\\\\D_y = 6.88 \ miles[/tex]
The magnitude of eastern displacement of the hiker is calculated as follows;
[tex]D_x = D \times cos(35)\\\\D_x = 12 \ miles \times cos(35)\\\\D_x = 9.83 \ miles[/tex]

At a butcher shop, Hilda bought 6 9/20 lb of beef and some pork. She left with 17 17/25 lb of meat. Express the number of pounds of pork she bought using a decimal.
Answer:
56.15
Step-by-step explanation:
First, convert [tex]6\frac{9}{20}[/tex] lbs to a decimal. Multiply the main number (6) by the denominator (20) and then add that number to the numerator (9). The number you will get will be (6 x 20)+9 = 129. 129 is now the new numerator as an improper fraction so the improper fraction is now [tex]\frac{129}{20}[/tex].
Now make [tex]17\frac{17}{25}[/tex] lbs an improper fraction. It would be [tex]\frac{442}{25}[/tex].
Now subtract the amount of pork from the total amount of meat. [tex]\frac{442}{25}[/tex] - [tex]\frac{129}{20}[/tex] . Find a common denominator. I'm going to use 500, although there might be something less.
[tex]\frac{5615}{100}[/tex] is the result. Now you can either start dividing or simplify the fraction, which hopefully you already know how to do. 5615 ÷ 100 = 56.15

What are the x-intercepts of the quadratic functions f(x) = (x + 7)(x − 5)?
Answer:
-7 and 5
Step-by-step explanation:
To tell what the x intercepts are you set both (x+7) and (x-5) equal to zero and then subtract/ add it to zero and then you have the answer. So x+7=0 would be x=-7 and x-5=0 would be 5
Choose the equation that has the
value of the variable furthest from
0 on a number line.
A) -4w= -7
B) 2x=3
C) y-1=-8
D) -1=z+4
Answer:
C) y -1 = -8
Step-by-step explanation:
The solutions to the various equations are ...
w = -7/-4 = 1.75 . . . . . divide by -4
x = 3/2 = 1.50 . . . . . . .divide by 2
y = -7 . . . . . . . . . . . . . .add 1
z = 5 . . . . . . . . . . . . . . add 1
The value farthest from 0 is y = -7, corresponding to choice C.
Corinne has a job selling magazines. She earns $7.50 per hour plus 20% of the total amount of her sales. She also gets an allowance of $40 per week for gas. She knows her weekly earnings can be shown using the following expression: 7.50h + 0.20s + 40 Part A: Identify a coefficient, a variable, and a constant in this expression. (3 points) Part B: If Corinne works for 25 hours and sells $300 in magazines, how much does she earn for the week? Show your work to receive full credit. (4 points) Part C: If Corinne gets a raise and begins earning $9 per hour, would the coefficient, variable, or constant in the equation change? Why?
Part A
The coefficient would be the number that is with a variable. The coefficient of 7.50h is 7.50. The variable is h, variables can be a letter or symbol that stands for something in a equation. For this question, h stands for the number of hours Corinne works. The constant is the number that is alone in the equation. That doesn't have a variable with it. In this equation the constant would be the number 40.
Part B
To solve this I will plug in 25 into "h" in and 300 for "s" in the equation 7.50h + 0.20s + 40 and then solve it.
25 × 7.50 = $187.5.
0.20 × 300 = $60
Total: $187.50 + $60 = $247.50 + $40 = $287.50
Part C
If Corrine gets a raise and earns $9 an hour the coefficient would change. It would be 9h instead of 7.50h.

Two competing gyms each offer childcare while parents work out. Gym A charges $9.00 per hour of childcare. Gym B charges $0.75 per 5 minutes of childcare. Which comparison of the child care cost is accurate?
Answer:
They are both the same.
Step-by-step explanation:
If you are doing for an hour for Gym B you would do .75 cents for ever 5 minutes of that hour.
60 minutes in an hour so
60/5=12
12*0.75=9.00
So both Gyms are the same.
What is the value of x in this equation: 4x + 5 = 3x + 4? Solve the equation using the algebra tiles.
Answer:
x = -1
Step-by-step explanation:
4x + 5 = 3x + 4
-5 -5
4x = 3x -1
-3x = -3x
1x = -1
x = -1
Answer:
x=-1
Step-by-step explanation:
4x+5=3x+4
subtract 3x from both sides of the equation
4x+5=3x+4
-3x -3x
x+5=4
subtract 5 from both sides of the equation
x+5=4

1/4a + 1/3a + 8 = 22 what would be the steps to solve this
Answer:
Step-by-step explanation:
first i would combine like terms so 1/4a + 1/3a is equal to 7/12 then the equation would be 7/12a+8=22 simplify the isolate the variable so i think it A=24
Answer:
Hey there!
Step-by-step explanation:
Equation: 1/4a + 1/a + 8 = 22
(The answer is 24)
(You have to do 3 steps in order to solve this question! The steps are below!)
~1. First you have to simplify both sides of the equation.
=> (1/4a + 1/3a) + (8) = 22
=> 7/12a + 8 = 22
~2. Next, subtract 8 from both of the sides.
After you do that you will get, 14
7/12a=14
~3. Lastly, you just multiply both sides by 12/7.
(12/7) x (7/12a)
(12/7) x (14)
~Therefore, A would equal to 24.
A=24
~Hope this helps!
~Good luck! :)

Identify the inequality for the given graph.
Answer:
We. can see there's a black point at -3.7 and an arrow going to the left.
As the arrow goes to the left, it must be less than -3.7 or less than or equal to -3.7, now, we will need to see the colour of the point to know which it is.
As there is a black point, -3.7 is also contained in this range...
What does that mean? That means it will be less than or equal to -3.7
So we know the correct option is a) less than or equal to -3.7, what we could write as ([tex]-\infty,-3.7[/tex]].
Camden is taking a multiple choice test with a total of 50 points available. Each question is worth exactly 5 points. What would be Camden's test score out of 50 if he got 2 questions wrong? What would be his score if he got x questions wrong
Answer:
Step-by-step explanation:
Score of 2 questions = 2 *5 = 10
He got 2 questions wrong. So, 50 - 10 = 40.
Camden's test score out of 50 = [tex]\frac{40}{50}[/tex]
Score for x questions = x *5 = 5x
Camden's score if he got 'x' questions wrong = 50 - 5x
