I'm going to assume that you meant the equation to be:
So we're going to take that equation and we're going to solve for h(-2).
This means that we plug in a '-2' for every x in the equation:
So when we solve the equation for h(-2), we get 0 as our answer.
Answer:
20
Step-by-step explanation:
You said 6, 9 or 20
Answer:
4
Step-by-step explanation:
The highest degree
$70 - 25% = 52.50
6% of 52.50 is 3.15.
52.50 + 3.15 = 55.65
D is the correct answer.
Answer:
see explanation
Step-by-step explanation:
given the 2 equations
y = x² - 2x - 19 → (1)
y + 4x = 5 → (2)
substitute y = x² - 2x - 19 into (2)
x² - 2x - 19 + 4x = 5 ( subtract 5 from both sides )
x² + 2x - 24 = 0 ← in standard form
(x + 6)(x - 4) = 0 ← in factored form
equate each factor to zero and solve for x
x + 6 = 0 ⇒ x = - 6
x - 4 = 0 ⇒ x = 4
substitute each value of x into (1) for corresponding y- coordinate
x = - 6 : y = (- 6)² - 2(- 6) - 19 = 36 + 12 - 19 = 29 ⇒ (- 6, 29)
x = 4 : y = 4² - 2(4) - 19 = 16 - 8 - 19 = - 11 ⇒ (4, - 11)
the solutions are (- 6, 29), (4, - 11)
