Answer:
x.
Step-by-step explanation:
If h(x) is the inverse of f(x) them h(f(x)) = x.
Answer:
Now we can solve a Quadratic Equation in 5 steps: Step 1 Divide all terms by a (the coefficient of x 2). Step 2 Move the number term (c/a) to the right side of the equation. Step 3 Complete the square on the left side of the equation and balance this by adding the same value to the right side of the equation.
Step-by-step explanation:
Answer:
50°
Step-by-step explanation:
(3x + 5) + (3x - 5) = 90
6x = 90
x = 15
∠P = 50°
Y= 4
z= -7
Substitute the given values above in for each variable in the expression below.
= 3y^2 + 2z
= 3(4)^2 + 2(-7)
using order of operations, square 4 before multiplying (PEMDAS: parentheses, exponents, multiplication, division, addition, subtraction)
= 3(16) + (-14)
a positive times negative is negative
= 48 - 14
= 34
ANSWER: 34
