-4x-y=-5 what is the slope
ivolga24 [154]

Answer:

-4

Step-by-step explanation:

The slope is the number (& sign) attached to the variable x.

Remember to follow the slope-intercept form: y = mx + b.

Isolate the variable y. Note the equal sign, what you do to one side, you do to the other. ∴

First, add 4x to both sides:

-4x (+4x) - y = -5 (+4x)

-y = 4x - 5

Next, divide -1 from both sides (to make the variably y positive):

(-y)/-1 = (4x - 5)/-1

y = (4x - 5)/-1

y = -4x + 5

Slope intercept form: y = mx + b, in which m = slope, ∴ -4 is your answer.

What is 4 and 3/4 - 1 and 1/3? The answer is one of these: 2 and 2/7, 2 and 2/12, 3 and 5/12, or 3 and 5/7
nignag [31]

Answer:

3 and 5/12

Step-by-step explanation:

4 \frac{3}{4}   = \frac{19}{4}\\ \\1\frac{1}{3}  = \frac{4}{3}

\frac{19}{4} - \frac{4}{3} \\\\\frac{19(3) - 4(4)}{12} \\\\\frac{57 - 16}{12} \\\\\frac{41}{12} \\

This fraction is equivalent to,

3 and 5/12 = 3\frac{5}{12} = \frac{12*3 + 5}{12} = \frac{41}{12}
