The aquarium has a scale model of a great white shark in there gift shop if the scale of the model is 2in 7ft what is the actual length of the shark​

answer:

solutions are (0,2) and (-1,4).

step-by-step explanation:

there are two equations given for which graphing is to be done.

equations are y = -2x+)

and y = -x²-3x+)

now we will solve the equations to get the values of x and y or the coordinates of intersection of these two graphs.

by substituting y from equation 2 into equation 1.

- x²-3x+2 = -2x+2

-x²-3x+2x = 0

-x²-x = 0

x²+x = 0

x(x+1)=0 ⇒ x = 0 and x = -1

now we put these values of x in equation 2.

for x = 0 y = -2×0+2 = 2

for x = -1 y = 2+2 = 4

so they intersect each other at (0,2) and (-1,4).
