These two lines cannot be perpendicular. For one line to be perpendicular to the second one, their gradients are related by the following:
Gradient of line 1 = -(1/gradient of line two)
In the current case, gradient of line 1=2 and gradient of line two = 1/2. If gradient of line two was = - 1/2, then they would be perpendicular.
8(v−4)+7v=−2
(8)(v)+(8)(−4)+7v=−2
8v+−32+7v=−2
(8v+7v)+(−32)=−2
15v+−32=−2
15v−32=−2
Add 32 to both sides.
15v−32+32=−2+32
15v=30
Divide both sides by 15.
15v/15=30/15
v = 2
write an expression that y plus 7 multiple by 3
Y + 7 X 3 = ?
