You have to make an equation that i forgot what was called but you just take
x+y=10 and multiply it by -2 so the y’s can cancel out
so you’ll end up with:
-2x-2y= -20
(+) x+2y=14
you’ll get : x = -6
then you plug in -6 for x, solve for y and your coordinates will be
(-6 , 10)
Answer:
591.1
Step-by-step explanation:
V=πr2h/3 v=π*8.4*2*8/3
v= volume = 591.1
h= Hight = 8
r= radius = 8.4
Answer:
b = 15.7 -2a
Step-by-step explanation:
You are asking us to solve for b
2a +b = 15.7
Subtract 2a from each side
2a-2a+b = 15.7 -2a
b = 15.7 -2a
Answer:
x < 5
Step-by-step explanation:
-7x + 14 > -3x - 6
Collect like terms
-7x + 3x > -6 -14
-4x > -20
Divide both sides by -4
-4x/-4 < -20/-4
Note : dividing both sides of an inequality by negative or minus the inequality sign changes.
Therefore
x < 5
