Answer: A

<u>Step-by-step explanation:</u>

f(x) = -x² - x + 6

= -(x² + x - 6)

= 1(x + 3)(x - 2)

So the zeros are: x = -3 and x = 2

We can stop here because there is only one graph that contains those x-intercepts (the first graph)

A pizza is divided into 12 pieces. Glenn and Sophie each ate 1/4 of the pizza on Thursday. The next day Sophie ate 1/3 of the pi

Natali5045456 [20]

Answer:

6 slices

Step-by-step explanation:

The full pizza is 12 pieces. Divide 12 by 4 to find out how much she ate on Thursday. 1/4 of 12 is 3 so she ate 3 slices on Thursday. Subtract 3 from 12 to find out how much was left for the next day. There were 9 slices the next day. Next, divide 9 by 3 to find out what 1/3 of 9 is. 1/3 of 9 is 3 so subtract 3 from the 9 slices. 6 slices are the original pizza remain.

Create an equivalent system of equations using the sum of the system and the first equation. x + 4y = 8 4x + y = 2

qaws [65]

Answer:

Equivalent systems of equations review

Step-by-step explanation:

We're given two systems of equations and asked if they're equivalent.

x + 4y = 8 (1)

4x + y = 2 (2)

Interestingly, if we sum the equations in System A, we get:

$x + 4y = 8 \\4x + y = 2 \\$
