3. Rewrite the expression as simply as you can:
3x + 11y - 2x - 4y

Answers

Answer 1

Answer:

Answer:

x+7y

Step-by-step explanation:

First off, lets split the question into both x and y.

3x - 2x for the x

11y - 4y for the y

You can solve both of them to get x + 7y

3x - 2x = x

11y - 4y = 7y

Then, add them back up and get x + 7y

Answer 2

Answer:

Answer:

x+7y

Step-by-step explanation:

3x + 11y -2x - 4y

(3x) + (11y) + (-2x) + (-4y)

(3x) + (-2x) = x

(11y) + (-4y) = 7y

3x + 11y -2x - 4y = x + 7y

k = 5 x 8 = 40
Therefore,
y = 40/14 = 2.86

What is the slope of the line represented by the equation y=4/5x-3

Answers

The slope of the line is 4/5 if the equation of the line is y = 4x/5 - 3 the answer is 4/5.

What is the slope?

The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).
