Step-by-step explanation:
7x + 8y + 5z
I put the equations in parentheses, assuming that I would be adding both of the equations together. Then, I removed them and combined the like terms. I used two calculators to check my answer, and this should be correct.
So x equals two if it is an exponent.9
Answer:
The interest is $35 so it ends up costing her $70
Step-by-step explanation:
Slope= (Y2-Y1)/(X2-X1)
Slope=(3-(-4) ) /(-14-(-7) )
Slope= (3+4)/(-14+7)
Slope=7/-7
Slope= -1
Answer:
y= -4x+22
Step-by-step explanation:
slope= -4
-6=-4(7)+b
-4x7=-28
-6=-28+b
28-6=22
so the equation would be y= -4x+22
b=y-intercept
mx=slope multiplied by x
