Roy: y=150-1.5x
Luis: y=200-2.5x
150-1.5x=200-2.5x
150=200-x
-50=-x
50=x
So in 50 weeks, Roy and Luis will weigh the same at 75 pounds each.
Answer:
x=120
Step-by-step explanation:
a vertical angle is equal to each other so if angle J is 120° the so is angle K
Answer:
I think this is the same as yesterday.
Answer:
11 2/3 pounds
Step-by-step explanation:
If a pack contain 1 2/3 pounds, 7 packs would contain :
1 2/3 x 7
× 7 = 35/3 = 11 2/3 pounds
Answer:
g⁻¹(x) = 2 + ∛x
Step-by-step explanation:
g(x) = (x - 2)³ Rename g(x) as y
y = (x - 2)³
Solve for x :
y = (x - 2)³ Multiply each side by 3
∛y = x - 2 Add 2 to each side
∛y + 2 = x
x = ∛y + 2 Switch x and y
y = ∛x + 2 Rename y as g inverse
g⁻¹(x) = 2 + ∛x
See the graphs of g(x) and g⁻¹(x) below.
g(x) is the red line. g⁻¹(x) is the blue line.
Each graph reflects the other about the dashed line representing the function y = x.
