<span>(2x-3)/x^2
if the number is –2
then
[2(-2) - 3] / (-2)^2
= (-4-3)/4
= -7/4
answer is

Answer:
g = 
Step-by-step explanation:
Given
t = v + 
Multiply through by g to clear the fraction
tg = vg + k ( subtract vg from both sides )
tg - vg = k ← factor out g from each term on the left side
g(t - v) = k ← divide both sides by (t - v)
g =

Answer:
x+y < 28
Step-by-step explanation:
1. Look at your variables: x is the first number and y is the second.
2. Know the limits: It says it has to be NO MORE than 28, so the inequality has to be less than (<) 28. And it says that the SUM of 2 numbers (in this case x and y), is no more than 28, so you know there's some addition between the two.
3. Write out your inequality: x+y < 28
