Use the parabola tool to graph the quadratic function y=-1? - 2.0 +8
Andreas93 [3]

Answer:

see explanation

Step-by-step explanation:

I don't have graphing facilities but can give you the vertex and 1 other point.

Given a parabola in standard form

y = ax² + bx + c ( a ≠ 0 )

Then the x- coordinate of the vertex is

x = - \frac{b}{2a}

y = - x² - 2x + 8 ← is in standard form

with a = - 1 and b = - 2 , then

x = - \frac{-2}{-2} = - 1

Substitute x = - 1 into the equation for corresponding value of y

y = - (- 1)² - 2(- 1) + 8 = - 1 + 2 + 8 = 9

vertex = (- 1, 9 )

To obtain another point substitute any value for x into the equation

x = 0 : y = 0 - 0 + 8 , then (0, 8 ) is a point on the graph

x = 2 : y = - (2)² - 2(2) + 8 = - 4 - 4 + 8 = 0  then (2, 0 ) is a point on the graph

Logic You find that the product of 93 and 6 is 558. He can you use addition to check your answer ? How can you use division yo c
frozen [14]
Addition: 93 can be added six times to determine the total

and division can be used to check your answer since it's the inverse operation of multiplication...take your solution of 558 and divide it by 6 (or 93) to see if 93 times six equals 558

12) Maxine went to the
Anna35 [415]
$0.29 * 3 = $0.87
$0.98 * 2 = $1.96
$1.39 * 1 = $1.39

0.87 + 1.96 = 2.83
2.83 + 1.39 = 4.22

10.00 - 4.22 = $5.78

she will get $5.78 back!
