Explain how solving -7y > 161 is different from solving 7y > -161. and you : d

Solving -7y > 161  is different from solving 7y > -161 is because a change of  symbol from > to > is required when solving -7y > 161 while 7y > -161 still maintains the greater than (>) symbol

The exercise is to explain how solving -7y > 161 is different from solving

7y > -161

For the inequality -7y  >  161

Multiply both sides by -1 and change the inequality sign from > to <

-1(-7y)  < -1(161)

7y   <   -161

Divide both sides by 7

7y / 7 <  -161/7

y   <  -23

For the inequality 7y > -161

Divide both sides by 7

7y/7  >  -161/7

y   >  -23

Solving -7y > 161  is different from solving 7y > -161 is because a change of  symbol from > to > is required when solving -7y > 161 while 7y > -161 still maintains the greater than (>) symbol

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
