Answer:

(d) y = -2x +8

Step-by-step explanation:

The parallel line will have the same x-coefficient, eliminating choices B and C. If it goes through point (4, 0), then (x, y) = (4, 0) will satisfy the equation.

A: 0 = -2(4) +4 = -4 . . . . . not true

D: 0 = -2(4) +8 . . . . . . . . true

The equation you're looking for is ...

y = -2x +8

<em>Additional comment</em>

Since you know the slope is -2 and a point on the line is (4, 0), you can use the point-slope form of the equation for a line as a starting point.

y -k = m(x -h) . . . . . . line with slope m through point (h, k)

For m = -2, and (h, k) = (4, 0), the equation becomes ...

y -0 = -2(x -4)

Simplified to slope-intercept form, this is ...

y = -2x +8

I need help ASAP !! Thanks

N=155. And since the other outer angle is also 155. And since the sum of all other angles is 360, you would take 360-155-155. That is 310. And so you would take 360-310=50. Since there is two angles, both m and p are equal to 25

What is the unit ratio for a button of 16 grams and 2 milliliters?

Reika [66]

Answer:

The unit ratio would be 8 grams per milliliters

Step-by-step explanation:

Since, the unit ratio is a fraction with denominator 1,

In other words, the amount of one quantity in unit amount of other quantity is called unit rate or unit ratio.

Here, the amount first quantity = 16 grams,

The amount of second quantity = 2 milliliters,

Thus, unit ratio = $\frac{\text{First quantity}}{\text{Second quantity }}$

$=\frac{16}{2}$ = 8 grams per milliliters

IF UR SMART U SHOULD KNOW THIS PLEASE HELP 10 POINTS

stellarik [79]

They're all simple.

150 = 25r

The r is multiplied for 25, so we should know what r equals to when it's not multiplied (1r).

So divide both terms for 25.

150/25 = 25r/25

6 = r

r = 6 <- answer

38 = 4p

Same thing here (divide both terms for 4)

38/4 = 4p/4

38/4 = p

p = 38/4 and simplify p = 19/2 <- answer

18 = a/20

We have a fraction, and we have to "delete" it.

There are two ways.

First one: multiply both terms for the denominator of the fraction.

18*20 = a/20 * 20

360 = a

a = 360 <- answer

Second way.

Take the two fractions to the common denominator (20) and do the LCM.

360/20 = a/20. Multiply both for 20

360 = a

a = 360

0 = 10x

0/10 = 10x/10

x = 0 <- answer

Explain what the vertical line test is and how it is used.

Alex Ar [27]

Answer: The vertical line test is used to determine if a graph of a relationship is a function or not. if you can draw any vertical line that intersects more than one point on the relationship, then it is not a function.

Hope this helped! :)
