Answer:

3(7j + 2 + 4j)

Step-by-step explanation:

We have to write an expression that looks like Sarah’s expression: 5(2j + 3 + j). We habr Replace the coefficients so that our expression is not equivalent. Also We may use any number that we choose to replace the coefficients ensuring to leave the variables the same.

Example, 3(7j + 2 + 4j) looks like Sarah’s expression but is not equivalent.

Choose the best graph that represents the linear equation:<br> 6x = y + 8

Agata [3.3K]

For this case we have that by definition, the equation of a line in the slope-intersection form is given by:

$y = mx + b$

Where:

m: It is the slope

b: It is the cut point with the y axis

We have the following equation:

$6x = y + 8\\y = 6x-8$

Thus, the cut point with the y axis is -8. Therefore, we discard options C and B.

It is observed that the slope is positive so the correct graph is option B.

Answer:

Option B

What is the equation of the line in the following graph? 1)y=x+2

Levart [38]

The slope-intercept form:

$y=mx+b$

m - slope

b - y-intercept

The formula of a slope:

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

We have two points (2, 0) and (-2, -4). Substitute:

$m=\dfrac{-4-0}{-2-2}=\dfrac{-4}{-4}=1$

Therefore we have the equation of a line

$y=1x+b\to y=x+b$

Put the coordinates of the point (2, 0) to the equation:

$0=2+b$ <em>subtract 2 from both sides</em>

$-2=b\to b=-2$

Answer: $\boxed{y=x-2}\to\boxed{3)}$

What is 5/7*w=40 1/2

sukhopar [10]

Answer:

56 7/10

Step-by-step explanation:

convert 40 1/2 to a fraction 40 1/2 = 81/2

multiply both sides by 7/5

this gets w by itself on the left

81/2 x 7/5 = 567/10 = 56 7/10
