Answer:
(-3,0) is the other x-intercept
Step-by-step explanation:
We know that the equation for the vertex form of a parabola is y=a(x-h)^2+k where (h,k) is the vertex.
Given (h,k) -> (1,-16) then we have y=(x-1)^2-16 as our equation.
Given that one x-intercept is at (5,0) we can plug in y=0 to find both:
0=(x-1)^2-16
0=x^2-2x+1-16
0=x^2-2x-15
0=(x-5)(x+3)
x=5 and x=-3
Therefore, the other x-intercept is (-3,0)
25 percent is the same as the decimal 0.25.
Multiply 100 by 0.25 to see what 25% of 100 is.
100x0.25=25
Then, to find the price raised by 25%, add 25 to 100.
100+25=125
The final answer is $125.
