B will b the answer that's the only answer yuh can get is b

**0**, **1**, or **2**.

See the attached graphs for examples. The red line is the quadratic equation, and the blue line is the linear equation.

We have that

y=x²<span>+3x-5

</span>y=4x+1

using a graph tool

see the attached figure

the solution are the points

(-2,-7)

(3,13)

<span>the solution obtained by the student

</span>(-2,0)

(3,0)<span>

is incorrect because the values of the coordinate y are incorrect

</span>the values of x are correct

x1=-2

x2=3

<span>with those values of x obtained, the student had to substitute it in any of the two equations to obtain the value of y

</span>so

for x=3

y=4x+1------> 4*(3)+1-----> y=13

for x=-2

y=4x+1------> 4*(-2)+1-----> y=-7

Supplements add up to 180°

so just subtract 164 from 180

180

<u>-164

</u> 16

**Answer:**

The new store will have a profit of $5400 after its fifth month.

(R-C)(x) = (x²+5x+14)-(x²-4x+5) = x²-x²+5x--4x+14-5 = 5x+4x+14-5=9x+9

(Use 5 for x)

(R-C)(5) = 9(5) + 9 = 45+9 = 54
