Answer:

the 3rd choice, 10x + 5, looks good

a coefficient is the number in front of a variable , so that's 10

a constant is a number w/o a variable ... so that's 5

I believe that the answer is 10x + 5.

Coefficents are also know as "multipliers". They pair with variables (in this case, that is x). Constants are simply numbers on their own.

Hope that makes sense.

Answer:

C) y = 12 x Represents the proportional relationship.

Step-by-step explanation:

Two quantities P and Q are said to be proportional if and only if:

$P \propto Q \implies P = k Y$

Here: K = Proportionality Constant

Now, here the given expression are:

$1. y = 7 x^2\\\implies y \neq kx$

So, y is NOT PROPORTIONAL to x.

$2. y = 2 + 3x\\\implies y \neq kx$

So, y is NOT PROPORTIONAL to x.

$3. y = 12 x\\\implies y = kx, k = 12$

So, y is PROPORTIONAL to x.

$2. y = 5 - x\\\implies y \neq kx$

So, y is NOT PROPORTIONAL to x.

What is the measure of ∠PQR ? Enter your answer in the box. °

xxTIMURxx [149]

The 3 inside angles of a triangle need to = 180 degrees
you are given 70 and 80 which = 150 degrees ( 70 +80 = 150)

so the missing angle (PQR) = 180 - 150 = 30 degrees

Which two triangles are congruent by the HL theorem? The diagrams are not to scale.

SOVA2 [1]

Hello there, and thank you for posting your question here on brainly.

The HL Theorem is when two triangles don't look the same but have the same side lengths.

I'm pretty sure triangles a and c are congruent.

Hope this helped!! ☺♥
