1 1/4 + 1 1/2

First change the mixed fractions into improper fractions.
Do this by multiplying the denominator by the whole number, then adding that to the numerator, leaving the denominator the same.

5/4 + 3/2

Now change the fractions so that they have a common denominator.
Here, you can use 4 as the CD, so leave the first fraction alone and just change 3/2.
3/2 = 6/4

5/4 + 6/4 = 11/4

11/4 can be changed into 2 3/4.

So the answer is 2 3/4 or 2.75.

9. Given 8x+4y = 4, identify the slope and y-intercept.

Elden [556K]

Answer:

A) Slope = -2 and y-int = 1

Step-by-step explanation:

The easiest way to get the slope and y-intercept from an equation is to put it in slope-intercept form: y = mx + b, where m is the slope and b is the y-intercept.

So, let's subtract 8x from both sides, leaving 4y on the left side:

8x + 4y = 4 -> 4y = -8x + 4

Now, let's divide both sides by 4, so that we can have just y on the left side:

y = -2x + 1

-2 is the slope, and 1 is the y-intercept.
