HURRY PLEASE I WILL GIVE BRAINLIEST AND LOTS OF POINTS
Mrac [35]

Answer:

m =  \dfrac{3}{4}

Step-by-step explanation:

We would like to find the <u>s</u><u>l</u><u>o</u><u>p</u><u>e</u><u> </u> of the line of the given equation .

\longrightarrow y =\dfrac{3}{4}x -1

We know that <u>s</u><u>l</u><u>o</u><u>p</u><u>e</u><u> </u><u>i</u><u>n</u><u>t</u><u>e</u><u>r</u><u>c</u><u>e</u><u>p</u><u>t</u><u> </u><u>f</u><u>o</u><u>r</u><u>m</u><u> </u> of the line is given by ,

\longrightarrow y = mx + c

where ,

  • m is the slope
  • c is y intercept

Now we can compare the given equation with the slope intercept form to find the slope . You will see that 3/4 is present at the place of m .Therefore ,

\longrightarrow \underline{\underline{m=\dfrac{3}{4}}}

Hence <u>o</u><u>p</u><u>t</u><u>i</u><u>o</u><u>n</u><u> </u><u>C</u><u> </u> is correct choice .

Solve for |2x + 4|-1=7
Rudik [331]

Answer:

x = - 6 or x = 2

Step-by-step explanation:

The absolute value function always returns a positive value. However, the expression inside can be positive or negative.

Given

| 2x + 4 | - 1 = 7 ( add 1 to both sides )

| 2x + 4 | = 8, thus

2x + 4 = 8 ( subtract 4 from both sides )

2x = 4 ( divide both sides by 2 )

x = 2

OR

-(2x + 4) = 8

- 2x - 4 = 8 ( add 4 to both sides )

- 2x = 12 ( divide both sides by - 2 )

x = - 6

As a check

Substitute these values into the left side of the equation and if equal to the right side then they are the solutions.

x = 2 → | 4 + 4 | - 1 = | 8 | - 1 = 8 - 1 = 7 ← True

x = - 6 → | - 12 + 4 | - 1 = | - 8 | - 1 = 8 - 1 = 7 ← True

Hence the solutions are x = - 6 or x = 2
