Answer:
y= 3, (-5/4)
Step-by-step explanation:
4y^2-7y=15
4y^2 - 7y -15
(y-3)(4y+5)
Answer:
Option A, 
Step-by-step explanation:
Given: Deborah bought a computer for
off the list price.
The list price is
.
To find: The amount Deborah spent on the computer.
Solution: We have,
List price of the computer
.
Deborah bought the computer for
off the list price.
The amount Deborah spent on the computer 
.
So, Deborah spent
on the computer.
Hence, option A is correct.
Answer:

Step-by-step explanation:
you have that the average sped is given by the following formula:

The uncertainty formula for a division is given by:
(1)
Δv: uncertainty in speed
Δx: uncertainty in the distance = 0.9m
Δt: uncertainty in time = 0.7s
x: distance = 8.1m
t: time = 1.7s
You replace the values of all parameters in the equation (1):

Hence, the relation between the uncertainty in the average velocity is 0.426
Solving Two- Step Equations:
First you have to add or subtract the number without the variable, x, then divide with the variable with x in it.
1.) -2 - 2=26
Answer: x= -14
Try some on your own, if you still need help comment back!
1. Add 4x back into -2, you now have -4y=-4x-2. Add +4 from y and now you are at y=-4x+2 and this is the answer!
2. Add -9x back into -3, you now have -4y=9x-3. Add +4 from y and now you are at y=9x-7 and this is your answer!!
I hope this helped! Brainliest? :) -Raven❤️
