Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Find points from graph.

Point (1, -5)

Point (7, -1)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute [SF]: $m=\frac{-1+5}{7-1}$
Add/Subtract: $m=\frac{4}{6}$
Simplify: $m=\frac{2}{3}$

Let f(x) = -2x - 7 and g(x) = -4x + 6. Find (fxg)(-5). a. -59 b. 3 c. 26 d. -6

DedPeter [7]

Answer:

Step-by-step explanation:

The given functions are:

$f(x) = - 2x - 7$

and

$g(x) = - 4x + 6$

$(f \times g)(x) = f(x) \times g(x)$

$(f \times g)(x) = ( - 2x - 7)( - 4x + 6)$

When we plug in x=-5, we get:

$(f \times g)( - 5) = ( - 4 \times - 5 + 6)( - 2 \times - 5 - 7)$

$(f \times g)( - 5) = ( 20 + 6)( 10 - 7)$

$(f \times g)(5) = ( 26)( 3) =7 8$

What value of x makes this equation true? 6x/-4=6(-1/2) a) -2 b)2 c)3 d)-3

Yuri [45]

6x/-4 = 6(-1/2)
6x/-4 = - 3...multiply by -4
6x = -3 * -4
6x = 12
x = 2
