14. 9(y - 4) - 7y = 5(3y - 2
step by step please
Answer:
y=-2
Step-by-step explanation:
9(y−4)−7y=5(3y−2)
(9)(y)+(9)(−4)+−7y=(5)(3y)+(5)(−2)
9y+−36+−7y=15y+−10
(9y+−7y)+(−36)=15y−10
2y+−36=15y−10
2y−36=15y−10
Step 2:
2y−36−15y=15y−10−15y
−13y−36=−10
Step 3:
−13y−36+36=−10+36
−13y=26
divide
/13 /13
y=-2
Answer:
y=-2
Step-by-step explanation:
Simplifying
9(y + -4) + -7y = 5(3y + -2)
Reorder the terms:
9(-4 + y) + -7y = 5(3y + -2)
(-4 * 9 + y * 9) + -7y = 5(3y + -2)
(-36 + 9y) + -7y = 5(3y + -2)
Combine like terms: 9y + -7y = 2y
-36 + 2y = 5(3y + -2)
Reorder the terms:
-36 + 2y = 5(-2 + 3y)
-36 + 2y = (-2 * 5 + 3y * 5)
-36 + 2y = (-10 + 15y)
Solving
-36 + 2y = -10 + 15y
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '-15y' to each side of the equation.
-36 + 2y + -15y = -10 + 15y + -15y
Combine like terms: 2y + -15y = -13y
-36 + -13y = -10 + 15y + -15y
Combine like terms: 15y + -15y = 0
-36 + -13y = -10 + 0
-36 + -13y = -10
Add '36' to each side of the equation.
-36 + 36 + -13y = -10 + 36
Combine like terms: -36 + 36 = 0
0 + -13y = -10 + 36
-13y = -10 + 36
Combine like terms: -10 + 36 = 26
-13y = 26
Divide each side by '-13'.
y = -2
Simplifying
y = -2

Point V lies between points U and W on line UW. The distance between U and V is 2x-4, and the distance between V and W is 4x+10. If UW = 9x – 9, what is UW in units?
Answer:
36UNITS
Step-by-step explanation:
If point V lies between U and W, then UV+VW = UW
given parameters
UV = 2x-4
VW = 4x+10
UW = 9x-9
Substituting the given functions in the formula first, we will have;
2x-4+4x+10 = 9x-9
6x+6 = 9x-9
Collect like terms
6x-9x = -9-6
-3x = -15
x = -15/-3
x = 5
Substitute x = 5 into UW.
Since UW = 9x-9
UW = 9(5)-9
UW = 45-9
UW = 36
Aaron throws a ball off the top of a building. The path of the ball can be modeled by
the equation y=-3x2 + 8x + 42 where y is the height of the ball and x is the time in
seconds since the throw.
A. How long will it take for the ball to hit the ground? Show all work to receive
credit
B. How tall is the building?
Answer: A: 60, since x = the amount of seconds and the 8 represents the seconds then you'll add 8x+42 and get 60
B: 54, now in this step find what -3x2 is which give you -6 since they're different signs then subtract and your answer will be 54

Tom worked 48 hours last week and gets time-and-a-half pay for overtime. His regular pay is $32 per hour. a) How much does he make for an hour of overtime?
Answer:
$48
Step-by-step explanation:
From the question we know that;
His regular pay is $32 per hour.
Tom worked 48 hours last week and gets time-and-a-half pay for overtime.
Time and a half pay = 1.5
Hence, if Tom works for an hour of overtime, his pay for his overtime is calculated as:
= 1.5 × $32 × 1
= $48
Therefore, he was paid $48 for one hour of overtime.
