1. 4r − 7b2. 2r − 7b3. 11rb4. 4r + 7b

4.

Step-by-step explanation:

Given : Jon and Lexi are playing a marble game.

According to their rules, 4 points are awarded for each red marble collected and 7 points are awarded for each blue marble collected.

Let r be the number of red marbles and b be the number of blue marbles.

Then , the expression represents Jon's total score if he has r red marbles and b blue marbles will be :-

597

step-by-step explanation:

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
