30 POINTS PLUS BRAINLIEST. ANSWER ALL QUESTIONS IN DETAILS, FORMULA AND STEP BY STEP. EXPLANATION FOR EACH ONE. NEEDS TO BE DONE IN 1HR OR LESS. ALL TROLL ANSWERS WILL BE REPORTED​

I think the answers below are all correct! :)

Step-by-step explanation: --> (that sign means I simplified the equation)

9-7r=-5 --> (9+5)-7r=0 --> 14-7r=0 --> 14=7r --> r=2

6x-5=4x+9 --> 6x=4x+(9+5) --> 6x=4x+14 --> 6x-4x=14 --> 2x=14 --> x=7

3(2d-1)=7d --> *multiply the parenthesis* 6d-3=7d --> -3=7d-6d -->d=-3

2(p-3)=4(3p+1) --> *multiply the parenthesis* 2p-6=12p+4 --> -10p=10 --> p=-1

Don't know how to do the others below the boxes.

Good Luck!

step-by-step explanation:

it's the only multiple of both and the least

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
