Answer:
70 degrees
Step-by-step explanation:
x = angle
180 - x = it's supplement
90 - x = it's compliment
(180 - x) - 4(90 - x) = 30
180 - x - 360 + 4x = 30
reducing
3x = 210
x = 70
Answer:
Step-by-step explanation:
The given function are;
f(x) = x² - 3·x - 12, and g(x) = -x - 12
Therefore;
g(-8) = -(-8) - 12 = 8 - 12 = -4
∴ f(g(-8)) = f(-4) = (-4)² - 3×(-4) - 12 = 16
Therefore;
Answer: I honestly have no clue
Step-by-step explanation:
Variables:
cost of 1 hot dog = x
cost of 1 hamburger = y
Set up a system of equations and use substitution
x + y = 2.75
x + 7y = 11.75
x + y = 2.75 can be rewritten as y = -x + 2.75
x + 7 (-x + 2.75) = 11.25
-6x + 19.25 = 11.25
-6x = -8
x = .75
plug x back into other equation to find y
y = -.75 + 2.75
y = 2.00
1 hot dog = $0.75
1 hamburger = $2.00
