Step-by-step explanation:

The gradient is

$\frac{2-5}{0-2}=-\frac{3}{2}$

So, using the y-intercept, the equation is

$y=-\frac{3}{2}x+2$

-2y-4=4(y-1) help me find the answer to this

Pepsi [2]

-2y-4=4y-4
2) cancel 4 out on both sides
-2y=4y
3) divide both sides by -2
y=-2y
4) subtract both sides by -2y
y+2y=0
5)3y=0
6) divide by 3

Y=0

Let f and g be two functions defined as

tia_tia [17]

$a) \: (f \times g)(x) = (2x + 5)( {x}^{2} - 7x + 5) \\ b) \: (f \times g)(4) = (2 \times 4 + 5)( {4}^{2} - 7 \times 4 + 5) = 13( - 7) = - 91$

Factor 2x 2 - 10x + 8 completely.

murzikaleks [220]

Answer:

2(x-1)(x-4)

Step-by-step explanation:

Begin by dividing each term by 2 and pulling the 2 to the front.

$2x^2-10x+8 = 2(x^2-5x+4)$

This is a trinomial. Trinomials are three term algebraic expressions typically featuring variables to exponent powers. To break these trinomials down we factor them using the diamond method or GCF. The diamond method states that for a trinomial $ax^2+bx+c$ multiply a*c then find two numbers which multiply to this number and add to b. When you find those numbers, write them as $(x-/+ number)(x-/+number)$ .

$x^2-5x+4$

a=1, c=4

ac=4 and add to b=-5 which -1 and -4 satisfy

The factored form is 2(x-1)(x-4).
