Find the slope of the line that passes through the points (1,-4) and (3,-1).
A)5/4
B)2/3
C)-3/2
D)3/2

Answers

Answer:

The slope of the line = m = 3/2

Hence, option D is correct.

Step-by-step explanation:

Given the points

(1,-4)(3,-1)

Determining the slope between  (1,-4) and (3,-1)

(x₁, y₁) = (1,-4)

(x₂, y₂) =  (3,-1)

Using the formula

Slope = m =  [y₂ - y₁] /  [x₂ - x₁]

               =  [-1 - (-4)] / [3 - 1]

               = [-1 + 4] / [2]

               = 3/2

Thus, the slope of the line = m = 3/2

Hence, option D is correct.

A tree in leilas backyard has been growing for 3 1/5 years. It is 3/4 meters tall how many meters per year?

Answers

Answer:

The tree grew 15/64 meters per year.                  

Step-by-step explanation:

Given

Length of a tree = 3/4 metersTotal time taken by the tree to grow 3/4 taller = 3 1/5 or 16/5 years

To determine

Per year growth of the tree in meters

Per year growth of the tree in meters can be determined by dividing the total length of a tree i.e. 3/4 meters by the total time taken by the tree to get 3/4 taller.

Per year growth of tree = Total Length  / Total time to grow

                                       = 3/4 ÷ 16/5

                                        = 3/4 × 5/16

                                        = [3×5] / [4×16]

                                        = 15/64 meters

Therefore, the tree grew 15/64 meters per year.                  

What is the value of x?
3 (-1 - 8x) = -3

Answers

Answer:

x = 0

Step-by-step explanation:

3 x -1 = -3 and 3 x -8x = -24x

-3 + 3( the opposite of the -3 given in the parentheses) = 0

-24x = 0

0/-24 (from -24x)= 0

Find the slope of the line that passes through the points. (-3, 5) and (1, 8).

Answers

Answer:

3/4

Step-by-step explanation:

To find slope, the equation is y(2)-y(1)/x(2)-x(1). So, your equation would look like: 8-5/1-(-3), which equals 3/4. Therefore, 3/4 is your answer.

lmk if it is right

Answer:

Step-by-step explanation:

In rectangle, diagonals bisect each other and diagonals are equal.

So, AE = DE

∠ADE = ∠DAE            {Angles opposite to equal sides are equal}

6x - 1 = 2x + 15

6x      = 2x + 15 + 1

   6x = 2x + 16

6x -2x = 16

4x      = 16

       x = 16/4

       x = 4

∠ADE = 6x - 1

         = 6*4 - 1

         = 24 - 1

        = 23

Lauren says that -3.5 is greater than -3 1/3. Do you agree? Explain.

Answers

Answer:

[tex]-3\frac{1}{2}<-3\frac{1}{3}[/tex]

Step-by-step explanation:

-3.5 means -(3 + [tex]\frac{1}{2}[/tex])

In other words, -3.5 = [tex]-3\frac{1}{2}[/tex]

When we draw two numbers [tex]-3\frac{1}{3}[/tex] and [tex]-3\frac{1}{2}[/tex] on a number line, [tex]-3\frac{1}{2}[/tex] comes first from left to right.

We know that all the numbers on a number line from left to right are in increasing order.

Therefore, [tex]-3\frac{1}{2}[/tex] is smaller than [tex]-3\frac{1}{3}[/tex].

[tex]-3\frac{1}{2}<-3\frac{1}{3}[/tex]

Lauren is not correct.

Answers

Isolate the variable by dividing each side by factors that don't contain the variable.

-6x-15+15=4x+35+15

-6x=4x+50
(Subtract 4 on both sides)

-10x=50
(Divide by 10 on both sides)

x=5

Answer:

x = -5

Step-by-step explanation:

-6x - 15 = 4x + 35

      + 15        + 15

-6x = 4x + 50

-4x   - 4x

-10x = 50

-10x/-10 = 50/-10

x = -5

Michelle compares 5.8 x 106and 2.32 x 107. What steps could she use to compare the two numbers?

Answers

Answer:

5.8 × 10^(6) is greater.

Step-by-step explanation:

The 2 numbers she wants to compare are;

5.8 × 10^(6) and 2.32 x 10^(7)

Now,for her to compare easily both numbers will need to have the same powers of 10.

To this effect, let's convert the power of ten of the second number to the power of 6.

We will divide by 10 to get it.

Thus; 2.32 x 10^(7) ÷ 10 = 0.232 × 10^(6)

Comparing 0.232 × 10^(6) to 5.8 × 10^(6), we can see that they have same power of 10 but the greater number that precedes the power of 10 is 5.8.

Thus, 5.8 × 10^(6) is greater.
