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:
y= 4/7x -1
Step-by-step explanation:
solve for y first in 4x-7y=9, which becomes y = 4/7x - 9/7, then since its a parallel line the slope stays the same which is 4/7. Then plug into this equation: y =mx+b, in which you plug in the point for the x and y values and you plug in the slope for m, so the equation becomes, 3 = (7)(4/7) + b and now solve for b in which b = -1 and now write the equation using all the corresponding things so the equation becomes: y= 4/7x -1
Answer
5.5cm
Step-by-step explanation:
The radius of a circle is the distance from the center of the circle to any point on its circumference.
The easiest way to find the radius is by dividing the diameter in half.
Radius = 1/2 × diameter
Here diameter is given as 11 cm.
Hence Radius = 1/2 × 11 cm.
= 11/2 cm.
= 5.5 cm.
Answer:
The angle is 30. It's complement is 60.
Step-by-step explanation:
Complementary angles add up to 90.
x + (5x-90) = 90
6x = 180
x = 30
