Hello!

8y - 1 = x
3x = 2y

Put what x equals in the first equation in place of x in the second equatoin

3(8y - 1) = 2y

Distribute the 3

24y - 3 = 2y

Subtract 24y from both sides

-3 = -22y

Divide both sides by -22

y = 3/22

Now we put y into the first equation

8(3/22) - 1 = x

Multiply

12/11 - 1 = x

Subtract

1/11 = x

The answer is (1/11, 3/22)

Hope this helps!

What is the factored form of the polynomial? X^2 -12+27?

Natali5045456 [20]

Answer:

(x-9)(x-3)

Step-by-step explanation:

Look to the number on the right, 27, and list out the factors. (1 and 27, 3 and 9, -1 and -27, -3 and -9)

Next, find the factors that would equal the middle number, -12, when added. -3 and -9 add to -12. Therefore, choose these numbers and put them in the form (x-9)(x-3).

∠ACE is formed by two secants intersecting outside of a circle. If minor arc BD = 25°, minor arc AB = 115°, and minor arc DE = 1

dmitriy555 [2]

Answer:

m∠ACE = 40°

Step-by-step explanation:

Consider the below figure attached with this question.

Given information: arc BD = 25°, minor arc AB = 115°, and minor arc DE = 115°.

We need to find the measure of ∠ACE.

minor arc AB + minor arc BD + minor arc DE + minor arc AE = 360°
