Answer:
the value of x=
2×-12= -24
the value of y is 3y plus 20 which equals to 23
The first one is (z-7)(z-1)
second: (x+1/3)(x+1/3)
third: (x-1/5)(x-1/5)
fourth: (x-5)(x-2)
Answer:
answer is 420-69
Step-by-step explanation:
because those numbers are great
Answer:
![y-a= c(x-b)^2](https://tex.z-dn.net/?f=%20y-a%3D%20c%28x-b%29%5E2)
With the vertex ![V= (b,a)](https://tex.z-dn.net/?f=%20V%3D%20%28b%2Ca%29)
We see that b = -10 and a = 2 and then the vertes wuld be:
![V= (-10,2)](https://tex.z-dn.net/?f=%20V%3D%20%28-10%2C2%29)
And the best option is:
b. (-10,2)
Step-by-step explanation:
For this problem we have the following function:
![y-2 = \frac{1}{2} (x+10)](https://tex.z-dn.net/?f=%20y-2%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20%28x%2B10%29)
And if we compare this expression with the general expression for a parabola given by:
![y-a= c(x-b)^2](https://tex.z-dn.net/?f=%20y-a%3D%20c%28x-b%29%5E2)
With the vertex ![V= (b,a)](https://tex.z-dn.net/?f=%20V%3D%20%28b%2Ca%29)
We see that b = -10 and a = 2 and then the vertes wuld be:
![V= (-10,2)](https://tex.z-dn.net/?f=%20V%3D%20%28-10%2C2%29)
And the best option is:
b. (-10,2)
