F(x) = -x + 4
Substitute x = -2 to the equation:
f(-2) = -(-2) + 4 = 2 + 4 = 6
Answer: A) 6
Answer:
x = 10
Step-by-step explanation:
Using the Pythagorean theorem:
8² + 6² = x²
64 + 36 = x²
x² = 100
x = 10
Answer:
Hello! answer: y = 40 x = 67
Step-by-step explanation:
63 - 23 = 40 therefore y = 40
63 + 63 = 126 360 - 126 = 234 234 ÷ 2 = 117
67 × 2 = 134 134 - 17 = 117 therefore x = 67 hope that helps!
Answer:
2
Step-by-step explanation:
Answer:
z=-3 so 2y+3(-3)=-8, 2y-9=-8, add 9 to both sides 2y=1 divide both sides by 2, y=1/2, so 3x+4(1/2)+-3=-2, 3x+2-3=-2, 3x-1=-2, add 1 to both sides, 3x=-1, divide both sides by 3, x=-1/3
