(20 POINTS!)

nadezda [96]

Answer:

Step-by-step explanation:

Please write 0,0 and 4,16. as points: (0, 0) and (4, 16). As we go from the first to the second point, x increases by 4 and y by 16. Thus, the slope of the line through these two points is

m = rise/run = 16/4 = 4.

This is the same result as

16 - 0

m = ------------ = 4

4 - 0

The length of a rectangle is two thirds its width. the area is 12 square meters. find its width. round your answer to two decima

ziro4ka [17]

L = $( \frac{2}{3} )$ w
a = 12
Length times width = area
L · w = a
$( \frac{2}{3} )$ w · w = 12
$( \frac{2}{3} )$ $w^{2}$ = 12
Divide both sides by $\frac{2}{3}$ or mulitply both sides by $\frac{3}{2}$ (either one is fine)
$( \frac{2}{3} )$ ÷ $( \frac{2}{3} )$ $w^{2}$ = 12 ÷ $( \frac{2}{3} )$
or
$( \frac{3}{2} )$ $( \frac{2}{3} )$ $w^{2}$ = 12 $( \frac{3}{2} )$
$w^{2}$ = 18
Square root both sides to get rid of the squared on the w
$\sqrt{w^{2} }$ = $\sqrt{18}$
w = 4.24

1)When adding two negative numbers, _________ the absolute value of the numbers and keep the negative sign.

butalik [34]

1) add.

for example -1 + -2 = - (||-1| + |-2||), which is -(1+2) or -3

2) subtract

for example 4 + -7 = -(||-7| + |4||), which is - |7 - 4| or -3

3) change
for example 3 - (- 2) = 3 + 2

4) -10

the sum is -10.25, which is closest to -10
