Answer:

y=1.5x+2

Step-by-step explanation:

Step 1, find slope

(20-8)/(12-4)

12/8 = 1.5

slope = 1.5

Step 2, find the y-intercept

y = 1.5x+b

use point (4,8)

8 = 1.5(4)+b

8 = 6+b

-6 -6

2 = b

Step 3, put it all in slope-intercept form (y = mx+b)

y = 1.5x+2

Answer: y = 1.5x+2

If ST = 12 and RT = 50 find RS. Use number line below

Inga [223]

Answer:

I believe RS is 38.

Step-by-step explanation:

RT is 50, which is the total length of the number line. ST is 12, which is one part of the line. To find RS. I believe you have to subtract 50-12 to get the length of the missing part. which is RS.

50-12 = 38

Solve for x 3(5x + 4) - 20 - 13x = -4

Strike441 [17]

3(5x + 4) - 20 - 13x = -4
first use the distributive property with 3(5x + 4)

15x+12-20-13x=-4
combine like terms

2x-8=-4
add 8 to both sides

2x=4
divide both sides by 2

x=2

The table shows the ratio of caramel corn to cheddar corn in a bag. What is the constant of proportionality?

Anit [1.1K]

For proportionality constant problems, set up the equation as,

$x=Ky$ ,

Where x and y are the two variables you are comparing and K is the proportionality constant. If we take Caramel Corn values as x and Cheddar Corn values as y, and then solve for K for each ratio lines, we will get the same answer. Let's check.

$15=K(10)\\K=\frac{15}{10}= \frac{3}{2}$ ,
