Answer:
x = 7/2 y = 5/2
Step-by-step explanation:
You can either use the elimiation or adding and subtracting method to get the variables for both x & y.
Once you solved for one variable, plug in the variable you just solved back into the original equation to find the other variable.
Answer:
x = -
, x = 2
Step-by-step explanation:
To find h(g(x)) substitute x = g(x) into h(x) , that is
h(g(x))
= h(x + 1)
= (x + 1)²
= x² + 2x + 1
For h(g(x)) = 3x² + x - 5 , then
3x² + x - 5 = x² + 2x + 1 ← subtract x² + 2x + 1 from both sides
2x² - x - 6 = 0 ← in standard form
(2x + 3)(x - 2) = 0 ← in factored form
Equate each factor to zero and solve for x
2x + 3 = 0 ⇒ 2x = - 3 ⇒ x = - 
x - 2 = 0 ⇒ x = 2

Just subtract to find the difference.
75 - (-25) = 75 + 25 = 100.
