Answer:

a. 4

b. -7

c. -7y+3x+9

Step-by-step explanation:

A. Okay well 5x, 9, -2x, and -7y are the 4 terms.

B. The coefficient (meaning the number attached to the y) is -7

C. Simplified would be finding the common variables; 5x and -2x. Subtract and you get 3x. You can't combine any more of your terms so you are left with -7y+3x+9

Points P, Q, and R are shown on the number line. What is the distance between point P and point Q? P(-76) Q(-24) R(0) A) 52 unit
Amiraneli [1.4K]

Answer:

A) 52 units

Step-by-step explanation:

The length of a line joining 2 points on a number line is given by the difference between the co-ordinates of the 2 points.

Therefore PQ= \left ( Q \right )-\left ( P \right )= \left ( -24 \right )-\left ( -76 \right )= 52

Hence the length of the line is 52 units
