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)
Answer:
The exact form would be 23/3
The mixed number form would be 7 2/3
If you think about it, 4x7 is half of 8x7 (If you multiply 4, 7, and 2, you get 8x7). So really you can just multiply 4x7 by 2 and you will get 8x7!
Answer:
I believe that this is what you mean. (y^3+3y+7)*(8y^2+y+1)
Step-by-step explanation:
So your answer would be: 8y^5+y^4+25y^3+59y^2+10y+7
Have a nice day!
I really hope this helps!
