Solve for x: -2(x+9)=5(x-7)

=

Step-by-step explanation:

Hey there! I will give the following steps, if you have any questions feel free to ask me in the comments below.

Step 1: Expand.

−2 − 18 = 5 − 35

Step 2: Add 2 to both sides.

−18 = 5x − 35 + 2

Step 3: Simplify 5 − 35 + 2 to 7 − 35.

−18 = 7 − 35

Step 4: Add 35 to both sides.

−18 + 35 = 7

Step 5: Simplify −18 + 35 to 17.

17 = 7

Step 6: Divide both sides by 7.

=

Step 7: Switch sides.

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.

i think the answer is b
