for z the fraction value is 1/26 and for other letters then Z is 25/26
Answer:
1.8
Step-by-step explanation:
cuz
if 1L is equal to 0.26
then 7×0.26
= 1.8
hope it helps
Answer:

Given:
f(x) = 2x² + 3
g(x) = x² - 7
To Find:
(f - g)(x)
Step-by-step explanation:
(f -g)(x) = f(x) - g(x)
= (2x² + 3) - (x² - 7)
= 2x² + 3 - x² + 7
= 2x² - x² + 3 + 7
= x² + 3 + 7
= x² + 10
The function in vertex form is
⇒ 3rd answer
Step-by-step explanation:
The vertex form of the quadratic function f(x) = ax² + bx + c is
f(x) = a(x - h)² + k, where
- a is the coefficient of x²
- (h , k) are the coordinates of the vertex point
, wher b is the coefficient of x- k = f(h), that means value f(x) when x = h
∵ f(x) = x² + x + 1
∴ a = 1 , b = 1
∵ 
- Substitute the values of a and b to find h
∴ 
∴ 
Substitute the value of x in f(x) by the value of h to find k
∵ f(
) = 
∴ f(
) = 
∴ f(
) = 
- k is the value of f(x) when x = h
∵ h = 
∴ k = f(
)
∴ k = 
Substitute the values of a, h and k in the vertex form
∵ f(x) = a(x - h)² + k
∵ a = 1 ,
, 
∴ 
∴ 
The function in vertex form is
