What is the vertex of the quadratic function fix=(x-8)(x-2)

VikaD [51]

Answer:

Vertex: (5, -9)

Step-by-step explanation:

fix = (x-8)(x-2)

fix = x^2 - 2x - 8x + 16

fix = x^2 - 10x + 16

a = 1, b = -10, and c = 16

To find vertex:

x = -b/2a

x = -(-10)/2(1)

x = 10/2

x = 5

y = 5^2 - 10(5) + 16

y = 25 -50 + 16

y = -9

Vertex: (5, -9)

(1) What is the equation, in point-slope form, for a line that goes through (8, −4) and has a slope of negative 5/6 (all fractio

Andreyy89

Formula for point-slope: $y - y1 = m(x-x1)$
Plug in the values (1): $y + 4 = -\frac{5}{6} (x - 8)$ {Choice B}
Plug in the values (2): $y + 6 = \frac{1}{3}(x+ 2)$ {Choice C}
_______________________

[For (3) and (4) we need to solve for slope]

(3)
First, solve for slope.
Formula for slope: $\frac{y2-y1}{x2-x1}$
Plug in values: $\frac{-1-5}{-4-7} = - \frac{6}{11}$
Slope: $- \frac{6}{11}$
Second, we must plug into point-slope form.
Formula for point-slope: $y - y1 = m(x-x1)$
Plug in the values: $y + 1 = - \frac{6}{11}(x + 4)$ {Choice C}

(4)
First, solve for slope.
Formula for slope: $\frac{y2-y1}{x2-x1}$
Plug in values: $\frac{6-(-8)}{-4-7} = - \frac{14}{11}$
Slope: $- \frac{14}{11}$
Second, we must plug into point-slope form.
Formula for point-slope: $y - y1 = m(x-x1)$
Plug in the values: $y - 6 = - \frac{14}{11}(x + 4)$ {Choice D}

Which toy pack cost of 2.50 per toy ?(brainlist will be given out)!!

Artemon [7]

Answer: Yo-yo

Concept:

In order to find the Cost Per Toy, we need to do the operation Cost / Toy.

Solve:

Slinky = Cost / Toy = 9 / 5 = $1.8 per toy

Wind-up robot = Cost / Toy = 16 / 8 = $2 per toy

Emoji beach ball = Cost / Toy = 3 / 2 = $1.5 per toy

Hope this helps!! :)
