Answer:

Step-by-step explanation:

Given

Required

Determine CD

Since Point C is on segment BD, then we have

Substitute x + 4 for BC; 5x for CD and 5x + 7 for BD

Collect Like Terms

Multiply both sides by -1

Substitute 3 for x in  

Hence, the length of CD is 15 units

Answer:

CD = 15

Step-by-step explanation:

Given

BC = x + 4

CD = 5x

BD = 5x + 7

Required

Determine CD

Since Point C is on segment BD, then we have

BD = BC + CD

Substitute x + 4 for BC; 5x for CD and 5x + 7 for BD

5x + 7 = x + 4 + 5x

Collect Like Terms

5x - 5x - x = 4 - 7

- x = -3

Multiply both sides by -1

x = 3

Substitute 3 for x in CD = 5x

CD = 5(3)

CD = 15

<em>Hence, the length of CD is 15 units</em>

The linear function has the domain (-2, -1, 0, 1, 2). Find the range or output of. h(x) = 2x + 3
lisov135 [29]

If the linear function has the domain (-2, -1, 0, 1, 2). Then the range of the function h(x) = 2x + 3 will be (-1, 1, 3, 5, 7).

<h3>What are domain and range?</h3>

The domain means all the possible values of x and the range means all the possible values of y.

The function is given as

h(x) = 2x + 3

The linear function has the domain (-2, -1, 0, 1, 2).

For x = -2

h(-2) = 2 (-2) + 3

h(-2) = -1

For x = -1

h(-1) = 2 (-1) + 3

h(-1) = 1

For x = 0

h(0) = 2 (0) + 3

h(0) = 3

For x = 1

h(1) = 2 (1) + 3

h(1) = 5

For x = 2

h(2) = 2 (2) + 3

h(2) = 7

More about the domain and range link is given below.

What is the value of x in the equation 1/3x − 2/3 =− 18?
Klio2033 [76]

Answer:

x = -52

Step-by-step explanation:

\frac{1}{3}x-\frac{2}{3}=-18

Let us solve for x.

\frac{1}{3}x=-18+\frac{2}{3}

\frac{1}{3}x=-\frac{18*3}{1*3} +\frac{2}{3}

\frac{1}{3}x=-\frac{54}{3} +\frac{2}{3}

\frac{1}{3}x=\frac{-54+2}{3}

\frac{1}{3}x=\frac{-52}{3}

Use cross multiplication to find the value of x.

\frac{1x}{3}=\frac{-52}{3}

3*1x=3*-52

3x=-156

Divide both sides by 3.

x = - 52
