alukav5142 [94]

Answer:

Step-by-step explanation:

To find the number of WHOLE pizzas needed, we need to divide the total number of slices needed (713) by 8 slices. Thus

$\frac{713}{8}=89.125$

because we can't order fractional pizza, we need to round up. So we will need 90 pizzas.

Write the following equation in slope -intercept form : y - 3 = 4(x + 2)

andreyandreev [35.5K]

Answer:

y=4x+11

Step-by-step explanation:

multiply 4 into the parentheses to get y-3=4x+8 then invert -3 so add three to both sides to get rid of it so instead of +8 its +11 so now its y=4x+11 and slope intercept is y=mx+b, so 4 is m, slope, and 11 is b, the y intercept i hope that helps
