-4x+4x +5y +6y = 17-6

11y=11

divide both side by 11 to isolate y

y=1

4x+6(1) = -6

subtract 6 on both sides

4x=-12

divide 4 on both sides

x=-3

Answer:

A or 24

Step-by-step explanation:

In PEMDAS you do the steps from left to right in the name.

So first, you do 3 * x and x = 6 so 3  * 6 which is 18.

then 18 + y and y = 8 so 26

26 minus 2 is 24.

Hope this helped~ ^-^

If you launch the cannonball from the ground instead (hi=0), what does that change in the original equation?
ikadub [295]

Answer:

  the value of hi changes from 58 to 0:

  h(t) = -4.9t^2 +19.8t

Step-by-step explanation:

If the initial height changes, then the term in the equation that represents that height will change. The initial height term is hi, so it changes from 58 to 0.

  h(t)=-4.9t^2+19.8t+0\\\\\boxed{h(t)=-4.9t^2+19.8t}

What is the average speed that robin mus drive to reach her friend's house 170 miles away in 2 1/2 hr
Tamiku [17]

68 miles / hour

Average speed = distance / time

distance = 170 and time = 5/2 ( as an improper fraction)

speed = 170 ÷ \frac{5}{2} = 170 × \frac{2}{5} = \frac{340}{5} = 68
