I think it is 17.50 because if you multiply $.50 by 7 you get $3.50. Then you multiply $3.50 by the 5 days to get $17.50
You cant simplify seven tenths
Make them both equal to y
y=-2x+6
2y=x+6 y=1/2x+3
These are perpendicular since ones slope is -2 and the other is the opposite, 1/2.
The formula to calculate the amount is 1200(1+0.03/4)^5
Option C
<em><u>Solution:</u></em>
We have to solve for "x"
From given,
Solve for brackets
Use distributive property
a(b + c) = ab + ac
Therefore,
Combine the constants
Move the variables to left side of equation
Combine the like terms
Thus option C is correct
