Angle 1 = 115°.

Because angle 4 = 65°, we know that the angle on the other side on 4 (with no number on it) must equal 180° when added to 65°. This is because they are supplementary angles, meaning that they add up to 180°. So if you do 180°-65°, you should get 115°, which is the measure of that angle.

Since the lines are parallel, that means that angle 1 and the angle outside of 4 must be equal, which means that angle 1 = 115°.

Hope this helps!

3x-4y+6=0 solve for y

DiKsa [7]

Answer: y=3/4x+3/2

Step-by-step explanation:

Let's solve for y.

3x−4y+6=0

Step 1: Add -3x to both sides.

3x−4y+6+−3x=0+−3x

−4y+6=−3x

Step 2: Add -6 to both sides.

−4y+6+−6=−3x+−6

−4y=−3x−6

Step 3: Divide both sides by -4.

−4y/−4= −3x−6/−4

y=3/4x+3/2

AC if TC = 20q + 10q^2?

Alexus [3.1K]

Answer:

AC = (20+ 10q)

Step-by-step explanation:

Given that,

Total cost, TC = 20q + 10q²

We need to find AC i.e. average cost.

It can be solved as follows :

$AC=\dfrac{TC}{q}\\\\AC=\dfrac{20q + 10q^2}{q}\\\\AC=\dfrac{q(20+ 10q)}{q}\\\\AC={(20+ 10q)}$

So, the value of AC is (20+ 10q).
