Answer:

The slope -41/4.

Step-by-step explanation:

Slope formula:

$\displaystyle \frac{Y_2-Y_1}{X_2-X_1}$

$\displaystyle \frac{61-20}{4-8}=\frac{41}{-4}=-\frac{41}{4}$

Therefore, the slope is -41/4, and the correct answer is -41/4.

If f(x)=5x+1 and g(x)=2f(x)+5 then g(-1)=

ollegr [7]

We know f(x)=5x+1. Plug in f(x) in the g(x) function.
We get $g(x)=2(5x+1)+5$ Distribute the 2 to 5x and 1.
$g(x)=10x+2+5$
Simplify to get $g(x)=10x+7$
Now, we plug in -1 for x.
$g(-1)=10(-1)+7$
$g(-1)=-10+7$
$g(-1)=-3$

Evaluate z + 2+ z for x = 2, y=-3, z = -4.

Artyom0805 [142]

Answer:

-6

Step-by-step explanation:

Are you sure that z + 2+ z is correct? x and y do not appear here.

z + 2+ z simplifies to 2z + 2, and so, if z = -4, z + 2+ z has the value

2(-4) + 2, or -6.
