Okay, so all this question wants you to do is plug in 2 for x and solve for your output, aka y.

y = -4x² - 8

when x = 2....
y = -4(2)² - 8

y = -16 - 8
y = -24

so, when your input is 2, your output is -24.

1/2 divided by5 in fraction form
erik [133]

Answer:

1/10

Step-by-step explanation:

1/2 ÷ 5

First you must use the form KCF, or Keep Change Flip

Keep the first integer (1/2)

Change the symbol (÷) > (×)

Flip the last remaining integer (5) > (1/5)

You remain with

1/2 x 1/5

Keep the numerator the same (since 1 x 1 = 1)

Multiply the denominators ( 2 x 5 = 10)

The answer is 1/10

Find the equation of the linear function represented by the table below in slope-
Anarel [89]

Answer:

y = 3x + 5

Step-by-step explanation:

slope:

11 - (-1) / 2 - (-2) = 12/4 = 3

slope intercept form is y = mx + b, so right now you have m = 3:

y = 3x + b

now, since you know x = -2 and y =-1 is a solution, you can plug those values in:

-1 = 3 * -2 + b

-1 = -6 + b

5 = b

This means the equation is y = 3x + 5

Answer:

\frac{8}{5} x^{2}  - \frac{16}{5} xy + 4x

xy^{2} + \frac{2}{3}y - 8y^{2}z

Step-by-step explanation:

We have to simplify the followings:  

1) - \frac{4}{5}x (- 2x + 4y - 5)

= - \frac{4}{5}x \times (- 2x) +  - \frac{4}{5}x \times (4y) + - \frac{4}{5}x \times (- 5)  

{By distributive property of multiplication}

= \frac{8}{5} x^{2}  - \frac{16}{5} xy + 4x (Answer)

2) 2y^{2}( \frac{1}{2} x + \frac{2}{6}y - 4z)

= 2y^{2} \times (\frac{1}{2} x) + 2y^{2} \times ( \frac{2}{6}y) - 2y^{2} \times (4z)

{By distributive property of multiplication}

= xy^{2} + \frac{2}{3}y - 8y^{2}z (Answer)
