Find the slope of the line that passes through the points (-12,10) and (-18,14).

9966 [12]

Answer:

-2/3

Step-by-step explanation:

To find the slope we use the formula

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

= ( 14-10)/(-18- -12)

= (14-10)/(-18+12)

= 4/-6

= -2/3

Which of the following expressions are equivalent to -2/3? select all that apply

Aleksandr-060686 [28]

Answer:

A.

C.

E.

Step-by-step explanation:

A

-1/9×6=

-1/9×6/1= -6/9 = -2/3

B

-15 ÷ 10

-15/1 ÷ 10/1

-15/1 × 1/10 = -15/10 = -3/2

C

12 ÷ -18 =

12/1 ÷ -18/1 =

12/1 × -1/18 = -12/18 = -2/3

D

-3/4 ÷ 1/2 =

-3/4 × 2/1 = -6/4 = -3/2

E

-8/9 × 3/4 = -24/36 = -2/3

Which number line represents the solutions to [X-5]=1

andreyandreev [35.5K]

we have

$\left|x-5\right|=1$

<u>Find the first solution (case positive)</u>

$(x-5)=1$

Adds $5$ both sides

$(x-5)+5=1+5$

$x=6$

<u>Find the second solution (case negative)</u>

$-(x-5)=1$

$-x+5=1$

Adds $(x-1)$ both sides

$-x+5+x-1=1+x-1$

$x=4$

therefore

the answer in the attached figure
