Answer:
-5 and 3
Step-by-step explanation:
you do thos so you can eliminate x and solve for y then substitute the answer to y in one of the equations to solve the equation
Answer:
If x represents the number of weeks for Jennifer, plug in 0 for x since we want to know the balance when it was opened.
So, 8(0)+30=f(x).
0+30=f(x)
30=f(x)
Step-by-step explanation:
She started her bank account with $30 dollars.
Here the time function is h(t) = [6 + 96t - 16t^2] feet.
The initial height of the ball is 6 feet. That's when t=0. h(0)=[6+0-0] ft = 6 ft.
At t=7 sec, h(t) = [6 + 96t - 16t^2] feet becomes
h(7 sec) = h(t) = [6 + 96(7) - 16(7)^2] feet This produces a large negative number (-106 ft), which in theory indicates that the ball has fallen to earth and burrowed 106 feet into the soil. Doesn't make sense.
Instead, let t=1 sec. Then h(1 sec) = h(t) = [6 + 96(1) - 16(1)^2] feet
=[6 + 96 -16] ft, or 86 ft.
One sec after the ball is thrown upward, it reaches a height of 86 feet. It continues to rise, slowing down, until it finally stops for an instant and then begins to fall towards earth.
multiply the numbers together to get the total
100* 12.065 =$1206.50
