Answer:

Graph 1: 2/9, 2: 1/2 3: 1/5

Step-by-step explanation:

To find slope you do y2-y1/x2-x1 (rise over run). For graph 1, y2=2, y1=0. x2=9,x1=0. 2-0=2, 9-0=0, so the overall slope is 2/9

PLEASE HELP ME WITH BOTH QUESTIONS<br> THANKS!!

First one:

cos(A)=AC/AB=3/4.24

cos(B)=BC/AB=3/4.24

Cos(A)/cos(B)=AC/AB / (BC/AB) = AC/AB * AB/BC = AC/BC=3/3=1


Second one:

To solve this problem, we have to ASSUME AFE is a straight line, i.e. angle EFB is 90 degrees. (this is not explicitly given).

If that's the case, AE is a transversal of parallel lines AB and DE.

And Angle A is congruent to angle E (alternate interior angles).

Therefore sin(A)=sin(E)=0.5

Simplify(5+2i)(1+3i)
hichkok12 [17]
(5 + 2i)(1 + 3i)

5 * 1 = 5

5 * 3 = 15i

2i * 1 = 2i

2i * 3i = 6i^2

So we have...

5 + 15i + 2i + 6i^2

5 + 17i + 6i^2

In order....

6i^2 + 17i + 5

A direct variation function contains the points (–8, –6) and (12, 9). Which equation represents the function?
mars1129 [50]

Answer:

y=\frac{3}{4}x

Step-by-step explanation:

If it is a direct variation function, then \frac{y}{x}=k.

k can be found by choosing a point and doing y divided by x.

So we can find k by doing -6 divided by -8 or 9 divided by 12.

Both of these values are equal to 0.75 or 3/4 as a fraction.

So you can say any point in this relation will follow the equation:

\frac{y}{x}=\frac{3}{4}

Multiply both sides by x:

y=\frac{3}{4}x
