Answer:
A: Ralph y = 10 + 7.50x
Frank y = 10x
B: x = 4, y = 40
C: x = 4 means that in order for the companies to make the same amount of money, they have to sell 4 shirts each. When the companies sell 4 shirts (or multiples of 4) they are making the same amount of money.
Step-by-step explanation:
Because both equations are equal to y, set them equal to each other.
10x = 10 + 7.50x
2.5x = 10
x = 4
Plug in x to a y equation.
y = 10(4)
y = 40
Answer:
I believe 21 cm
Step-by-step explanation:
Answer
y=-\frac{11}{13}x+\frac{8}{13}
Step-by-step explanation:
Sin(angle) = Opposite leg / Hypotenuse
Angle = 8 degrees
Opposite leg = 2.3 feet
Sin (8) = 2.3 ft. / Z
Z = 2.3 / sin(8)
Z = 16.5 feet
