Type the correct answer in each box.
solve the quadratic equation. write your solutions in the blanks, starting with the smaller value.

4x2– 7 = 9

x = ±2 (x = 2 or -2)

Start with the equation .

Add 7 on both sides of the equation to get .

Divide both sides by 4 to get .

Now, find the square root of each side to get a final answer of , which means x can be either 2 or -2.

where is the triangle?

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.
