Step-by-step explanation:

\frac{2}{ - 6}  =  \frac{ - 7}{y}  \\ y =  \frac{( - 6) \times  (- 7)}{2}  \\ y =  \frac{42}{2}  \\  \boxed{y = 21}

<h2>21 is the right answer.</h2>

Find the measure of angle
madreJ [45]

9514 1404 393

Answer:

  (b)  62°

Step-by-step explanation:

Let x represent the measure of the angle.

The complement is (90 -x).

The supplement is (180 -x).

The relationship between the supplement and the complement is ...

  (180 -x) = 6 +4(90 -x)

  180 -x = 6 +360 -4x

  3x = 186

  x = 62

The measure of the angle is 62°.

How do I factor x^2-12x-364?
RoseWind [281]

Answer:

(x - 26)(x + 14)

Step-by-step explanation:

We need to find 2 numbers that add up to -12 and multiply to -364.

We know we will need one positive number and one negative number:

-26 and 14 work to multiply to -364.

-26 and 14 add up to -12.

∴ (x - 26)(x + 14)

Ok this might be wrong but you don’t have much time so I will give my best

I’m pretty sure the of the x and y thing you do this you see the box with the number in it do this the top two says 2 and 4 the left side is x and the right side is y so you see at the bottom of the number Line thing on the right is a little x that where you start so the box of numbers the fist one says 2 so go to the bottom number line and there is the number two now the top right box with numbers says 4 so go up 4 squares from the number 2 and make a dot where they come together

Pls help me out!! Ill be so happy!! TYSM
mr Goodwill [35]

Answer:

Hey there!

The line 4x-3y=-9 can be converted to y=mx+b form.

4x-3y=-9

-3y=-4x-9

3y=4x+9

y=4/3x+3

The slope of a line perpendicular to this line would be -3/4.

The slope of a line parallel to this line would be 4/3.

Hope this helps :)
