Answer: 1

Step-by-step explanation:

6 times 2 minus 2y = 10

first 6x2=12

12-2y=10

minus 12 from each side =0

so now you have;

-2y= -2

divide & you get one!

If alpha and beta are the zeroes of the polynomial f(x)= xsquare -8x +gamma such that alpha - beta = 2 find the value of gamma.

Komok [63]

Answer:

Γ = 15

Step-by-step explanation:

Given

f(x) = x² - 8x + Γ

with a = 1, b = - 8 and c = Γ , then

sum of zeros α + β = - $\frac{b}{a}$ = - $\frac{-8}{1}$ = 8

product of zeros = αβ = $\frac{c}{a}$ = Γ

Given α - β = 2 , then

(α - β)² = 2²

α² - 2αβ + β² = 4 → (1)

and

(α + β)² = 8²

α² + 2αβ + β² = 64 → (2)

Add (1) and (2) term by term

2α² + 2β² = 68 ( divide through by 2 )

α² +β² = 34

Substitute α² + β² = 34 into (1)

34 - 2αβ = 4 ( subtract 34 from both sides )

- 2αβ = - 30 ( divide both sides by - 2 )

αβ = 15

Now

αβ = Γ = 15

Thus

f(x) = x² - 8x + 15

bekas [8.4K]

Answer:

81x²+180x+100
9x²+180x+10²
using (a+b)²=a²+b²+2ab
9x²+2(9x)(10)+10²
(9x+2)²=(9x+2)(9x+2)

Hey what's the answer ? <img src="https://tex.z-dn.net/?f=%28x%20-%20y%29" id="TexFormula1" title="(x - y)" alt="(x - y)"

Varvara68 [4.7K]

Answer:

 -1

Step-by-step explanation:

here's your solution

=> The value of x = 1

=> The value of y = 2

=> we need to find ( x - y)

=> so, put the value of above variables in it

=> hence, (1 - 2) = - 1

=> - 1 is correct answer

hope it helps

Match the lengths of the hypotenuse and one leg of a right triangle to the length of the other leg.

Lynna [10]

1. D
2. B
3. A
4. C
Basically always use a^2 + b^2 = c^2 it gives you your A and C so subtract your A from you C and you have your B
