Find an equivalent system of equations for the following system:
x + 2y = 2
−4x + 4y = −8
a) x + 2y = 2
−4x − 2y = 10
b)x + 2y = 2
5x + 4y = 8
c)x + 2y = 2
5x − 2y = 10
d)x + 2y = 2
5x − 2y = −8

Option C

Step-by-step explanation:

we have

x+2y=2 > equation A

-4x+4y=-8 > equation B

Multiply equation B by -1 both sides

-1(-4x+4y)=-8*(-1)

4x-4y=8 > equation C

Adds equation A and equation C

x+2y=2

4x-4y=8

5x-2y=10 > equation D

An equivalent system of equations is equation A and equation D

so

x+2y=2 > equation A

5x-2y=10 > equation D

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.
