**giving brainliest** the concession stand sells hot dogs and soda during beck high school football games. john bought 6 hot dogs and 4 sodas and paid 10.50. jessica bought 4 hot dogs and 3 sodas and paid 7.25. what is the cost of one hotdog?

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15

the answer is 1030 it's very simple math.

step-by-step explanation:

a'(12.5,11.25)

slope=(y1-y2)/(x1-x2)

(5x-1)^2= (5x)^2-2(5x)×1+(1)^2=25x^2-10x+1
