Answer:

The second one would be the correct option.

Step-by-step explanation:

The guy above is wrong, the second one is right, I took the assignment.

The guy above is right for the answer on number eight though because there are two of these types of questions asked on this same assignment. I think he got the two questions mixed up, but for question eight he is right, but for question five the second graph is the correct answer.

What is the y-value of the vertex of the function f(x)=-(x+8)(x-14)? 3 6 112 121

MAXImum [283]

Answer:

121

Step-by-step explanation:

Given

f(x) = - (x + 8)(x - 14) ← expand factors using FOIL

= - (x² - 6x - 112) ← distribute by - 1

= - x² + 6x + 112

Given a quadratic in standard form. y = ax² + bx + c : a ≠ 0

Then the x- coordinate of the vertex is

$x_{vertex}$ = - $\frac{b}{2a}$

f(x) = - x² + 6x + 112 ← is in standard form

with a = - 1 and b = 6, thus

$x_{vertex}$ = - $\frac{6}{-2}$ = 3

Substitute x = 3 into f(x) for corresponding value of y

f(3) = - (3)² + 6(3) + 112 = - 9 + 18 + 112 = 121

vertex = (3, 121 ) ← with y = 121

In early spring, you buy 6 potted tomato plants for your container garden. The plants contained in 8 inch pots sell for $5 and t

X - the number of plants in 8 in pots
y - the number of plants in 10 in pots

$x+y=6\\
5x+8y=36\\\\
x=6-y\\
5x+8y=36\\
5(6-y)+8y=36\\
30-5y+8y=36\\
3y=6\\
y=2\\\\
x+2=6\\
x=4$

4 plants in 8 in pots and 2 in 10 in pots.

What is AE ? Enter your answer in the box. units:

Diano4ka-milaya [45]

(2x+6)/10 = (x+6)/8
10(x+6) = 8(2x+6)
10x + 60 = 16x + 48
6x = 12
x = 2

so
AE = 2(2) +6
AE = 4 + 6
AE = 10
