Answer:x=−136
Step-by-step explanation: Step 1: Simplify both sides of the equation.
2+x=
7
8
x−15
2+x=
7
8
x+−15
x+2=
7
8
x−15
Step 2: Subtract 7/8x from both sides.
x+2−
7
8
x=
7
8
x−15−
7
8
x
1
8
x+2=−15
Step 3: Subtract 2 from both sides.
1
8
x+2−2=−15−2
1
8
x=−17
Step 4: Multiply both sides by 8.
8*(
1
8
x)=(8)*(−17)
Y=x-7 this is because you subtracted the x to both sides. Since y is a negative, you divide by -1 causing the -x to turn positive and the positive seven to be negative seven.
It is negative because the plot is going down not up
14 days = 2 weeks
20weeks : 14 days = 20 weeks : 2 weeks = 20 weeks / 2 weeks = 10:1
hope it helps!
