Well, we know that x=7
Plug that into the given equation, 14x-2
14(7) = 98
Then 98-2 = 96
96 is your final answer !!
So basically in the equation just replace ‘x’ with 7, because they are equal to each other!
Hope this helped
Answer:
The height of the stone at the time it is thrown is 15.
Step-by-step explanation:
You have a quadratic function of the form h (x) = ax² + bx + c. In this case it is h (x) = -5x²+10x+15, where a =-5, b =10, c =15, x is the time and h (x) is the height of the stone after being thrown.
The moment the stone is thrown is instant zero. So if x = 0, h (0) is calculated:
h(0)= -5*0² +10*0 +15
h(0)= 0 + 0 + 15
h(0)= 15
The height of the stone at the time it is thrown is 15.

First table: 2x+1=y
Second table: 3x+2=y
Step-by-step explanation:
It was really just testing it out, checking to see if an equation worked for one row, then try in the next. Its hard to explain, but its really just guess and check ;D
