Jack is wrong because he used the distributive property wrong. On the top equation, you see 2(4k - 3). The 2 multiplies into the (), so basically you have

2 x 4k - 2 x 3

which gives you

8k - 6

Answer:

Taniyah

Step-by-step explanation:

Taniyah is correct because you need to:

diistribute : 8k - 6 - 6k = 14

combine like terms : 2k - 6 = 14

add 6 to both sides : 2k - 6 + 6 = 14 + 6

simplify : 2k = 20

divide both sides by the same factor : 2k/2 = 20/2

simplify : k = 10

Determine the slope for the line that meets each condition stated. Show your work. Passes through the points ( 3 , 5 ) and ( − 1

Kamila [148]

Answer:

The slope of the line that passes through (-1, -7) and (3, 5) is 3

Explanation:

The slope of the line is calculated using the following rule:

$Slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

We are given the following points:

(3 , 5) representing (x₁ , y₁)

(-1 , -7) representing (x₂ , y₂)

To get the slope, we will simply substitute with the givens in the above equation

This is done as follows:

$Slope = \frac{-7-5}{-1-3}=3$

You haven't attached the table for the second part. However, follow the same procedure. Pick two points from the table, substitute with them in the above equation and you'll get the slope

Hope this helps :)

The sum of two numbers is 89. Three times the smaller

Ymorist [56]

Answer:

The numbers are 40 and 49

Step-by-step explanation:

Smaller number = x

Larger number = y

Let's write our system of equations:

x + y = 89

3x = y + 71

***************************

x = 89 - y

Substituting x in the 2nd equation and solving for y:

3 (89 - y) = y + 71

267 - 3y = y + 71

-3y - y = 71 - 267 (Like terms)

-4y = - 196

y = -196/-4

y = 49

Solving for x in the 1st equation:

x + y = 89

x + 49 = 89

x = 89 - 49

x = 40

The numbers are 40 and 49
