<span> zeros of the quadratic function when f(x) = 0
so 
</span><span>8x^2 – 16x – 15 = 0
(8x + 5)(x - 3) = 0
8x + 5 = 0; x = -5/8

Assume that y varies inversely
Marina86 [1]

Answer:

y = 2

Step-by-step explanation:

y varies inversely with x setup is:

y = k/x

7 = \frac{k}{2/3}  (find 'k')

k = 7/1 · 2/3

k = 14/3

use what you know about 'k' and 'x' to solve for 'y'

y = 14/3 ÷ 7/3  (remember to multiply by the reciprocal when dividing fractions)

y = 14/3 · 3/7

y = 2

A triangle has vertices at B(-3,0), C(2, -1), D(-1,2). Which series of transformations would produce an image with vertices B"(4
Alik [6]

Answer:

  (b)  (x, y) ⇒ (-x, y); (x, y) ⇒ (x + 1, y + 1)

Step-by-step explanation:

A graph shows the image is consistent with reflection over the y-axis

  (x, y) ⇒ (-x, y)

and translation right 1, up 1

  (x, y) ⇒ (x +1, y +1)

These transformations are listed in the second choice.

__

In the attachment, the original image is blue, the reflected image is purple, and the final translated image is red.

Orange crayons are usually made in batches of 100. If it takes 22 pounds of wax to make 100 orange crayons,then how much wax wil
bogdanovich [222]

Amount of wax required for one orange crayon is 0.22 pounds.

Step-by-step explanation:

According to given statement;

22 pounds of wax = 100 orange crayons

For calculating wax for one crayon;

Wax required for one crayon = Total pounds of wax / Total no of crayons

Wax required for one crayon = \frac{22}{100}

Wax required for one crayon = 0.22

Amount of wax required for one orange crayon is 0.22 pounds.
