Answer:

z = 92

Step-by-step explanation:

9 (z - 82) = 90

Divide both sides by 9

z - 82 = 90/9

z - 82 = 10

add 82 to both the sides,

z - 82 +82 = 10 +82

z = 92

URGENT HELP What is the equation of the line that passes through the point (-7, -4) and has a

shepuryov [24]

The final equation is:

$y=x+3$

Further explanation:

The general form of equation of a line in slope-intercept form is:

$y=mx+b$

Here m is the slope

Given

m=1

(x,y) = (-7,-4)

$Putting\ the\ value\ of\ slope\ in\ equation\\y=(1)(x)+b\\y=x+b$

To find the value of b, we have to put the point in the equation

$-4=-7+b\\-4+7=b\\b=3$

The final equation is:

$y=x+3$

Answer:

slope = k/2

Step-by-step explanation:

The slope formula is useful for finding slope.

m = (y2 -y1)/(x2 -x1)

m = (5k -7k)/(-3 -1)

m = -2k/-4

m = k/2

The slope is k/2.
