If y varies directly as x, and y is 6 when x is 72, what is the value of y when x is 8

Xelga [282]

Answer:

Y varies directly as X.

y=kx.

6=K72.

x=6/72.

x=0.08.

Y=0.08x.

when y=?, x=8.

y=0.08×8=0.64.

What is the slope of the line that passes through the points (-2, -1)(−2,−1) and (2, -3) ?(2,−3)? Write your answer in simplest

erica [24]

The slope of line that passes through given points is -1/2

Step-by-step explanation:

The formula for slope is:

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

Given points are:

(-2,-1) = (x1,y1)

(2,-3) = (x2,y2)

Putting the values in the formula of slope

m = $=\frac{-3-(-1)}{2-(-2)}\\=\frac{-3+1}{2+2}\\=\frac{-2}{4}\\=-\frac{1}{2}$

The slope of line that passes through given points is -1/2

Answer:

9. 6k + 5 and 2k - 1.

10. 5√2 .

Step-by-step explanation:

9. Area = 12k^2 + 4k - 5

Factoring:

12k^2 - 6k + 10k - 5

= 6k(2k - 1) + 5(2k - 1)

= (6k + 5)(2k - 1)

So the required lengths are 6k + 5 and 2k - 1.

10. The ratio of a leg to the hypotenuse is 1: √2 so if the hypotenus = 10 the length of a leg is 10 / √2

= 10 √2 / 2

= 5√2 .
