What's the equation answer to-28= 7(n+3)

n=−7

Step-by-step explanation:

Simplify both sides of the equation.

−28=7(n+3)

−28=(7)(n)+(7)(3)

(Distribute)

−28=7n+21

Step 2:Flip the equation.

7n+21=−28

Step 3: Subtract 21 from both sides.

7n+21−21=−28−21

7n=−49

Step 4: Divide both sides by 7.

7n/7=-49/7

n=−7

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.
