Answer: y = 4/5x + -17/5

Step-by-step explanation:

Step 1: Add -4x to both sides.

4x−5y+−4x=17+−4x

−5y=−4x+17

Step 2: Divide both sides by -5.

-5y/-5 = -4x + 17/5

Answer:

Step-by-step explanation:

180 -40 - 90 = 50

I don't remember the name of the type of angle, but since that one angle is 50 the other side is also 50.

180 - 90 - 50 = 40

Tell me if I am wrong.

1. Find the Least Common Multiple of these two monomials: See picture

gtnhenbr [62]

Answer:

The last choice is correct

$LCM=120a^4b^7c^5$

Step-by-step explanation:

Least Common Multiple (LCM)

To find the LCM we can follow this procedure:

List the prime factors of each monomial.

Multiply each factor the greatest number of times it occurs in either factor.

We have two monomials:

$12a^4b^2c^5$

$40a^3b^7c^1$

The prime factors of the first monomial are:

$2^2,3,a^4,b^2,c^5$

The prime factors of the second monomial are:

$2^3,5,a^3b^7c^1$

LCM = Multiply $2^3*3*5*a^4*b^7*c^5$

These are all the factors the greatest number of times they occur.

Operating:

$LCM=8*15*a^4*b^7*c^5$

$\boxed{LCM=120a^4b^7c^5}$

The last choice is correct
