Answer:

The value of b is 21

Step-by-step explanation:

29=√20^2+b^2

or, 29=√400+b^2

or, 841=400+b^2

or, 841-400=b^2

or, √441=b

b=21

The value of y varies directly with x, and y= -10 when x=40. Identify the value of y when x=-5

scoray [572]

Answer:

y = 1.25

Step-by-step explanation:

Use the direct variation equation y = kx, and solve for k:

y = kx

-10 = k(40)

-0.25 = k

So, the equation is y = -0.25x. Solve for y when x = -5

y = -0.25x

y = -0.25(-5)

y = 1.25

So, y = 1.25 when x = -5

What is the slope of the line represented by the equation y = –y equals negative StartFraction 2 Over 3 EndFraction minus 5 x. –

Nutka1998 [239]

Answer:

The slope is $m=-5$

Step-by-step explanation:

we know that

The equation of the line in slope intercept form is equal to

$y=mx+b$

where

m is the slope

b is the y-intercept

In this problem we have

$y=-\frac{2}{3}-5x$

Rewrite

$y=-5x-\frac{2}{3}$

This is the equation of a line in slope intercept form

The slope is $m=-5$

The y-intercept is $b=-\frac{2}{3}$
