Check all the equations that apply to meet the Segment Addition

Mathematics
1 answer:
Jlenok [28]3 years ago
7 0

Answer:

Options (2) and (5)

Step-by-step explanation:

Given in the question,

Length of OQ = 45

OP = (6x + 5)

PQ = 4x

By segment addition postulate,

Length of a segment OQ = length of segment OP + length of segment PQ

45 = 6x + 5 + 4x

10x + 5 = 45

10x = 45 - 5

10x = 40

x = \frac{40}{10}

x = 4

Therefore, Option (2) and Option (5) are the correct options.

Help would be great thank you!
Reil [10]

Answer:

I think 3x doesn't belong because it is the only positive number.

I think -5x doesn't belong because it is the only one without a 3.

I think -3 doesn't belong because it is the only one without an x.

I think -3x² doesn't belong because it is the only one with an exponent.

Step-by-step explanation:

Just use one of the ones above!

(hope this helps!)

The graph of the function B is shown below. If B(x) = -1, then what is x?
Schach [20]

Answer:

"(1.) 2"

Step-by-step explanation:

Whenever we are given a notation such as:

A(x) = z

We can say that for the value of x, we get a value of z

The x value is the x-coordinate and the z value is the y-coordinate that corresponds to it in the graph.

We are given,

B(x) = -1

So, we can say:

at a certain x value the y-value is -1

Now, we look at y = -1 line and find the point.

This is the "lowest" point on the graph shown that corresponds and falls on y = -1. Now, which x-value does it correspond to??

<em>It corresponds to x = 2, because it is located at 2 units in x-direction and down 1 unit (which is y = -1).</em>

<em />

<em>So x value is x = 2</em>

<em>Answer choice 1 is right.</em>

<em>(1.) 2</em>

What is | -7.9 ?<br> help
Tamiku [17]
I think you mean |-7.9| which is the absolute value of 7.9
Absolute value just means how far away it is from zero on a number line.
So the value is always positive. So the positive of -7.9 is 7.9
|-7.9|= 7.9
Good luck!

What is the slope of a line that is perpendicular to the line represented by the equation x – y = 8?
Kay [80]

Answer:

the slope would be equal to -x or -1

Step-by-step explanation:

First rewrite the equation in correct slope intercept form. Subtract x from both sides and then divide both sides by a negative sign.

  x - y = 8

-x            -x

\frac{-y}{-} =\frac{-x+8}{-}

y= x +8

A perpendicular slope is the inverse of the original slope. If the original slope is 2 then the perpendicular slope would be -1/2. In this problem the original slope is 1. The inverse of 1 is -1

Drag and drop numbers into the equation to complete the equation of the line in slope-intercept form.
lara31 [8.8K]

Answer:

y = 4x - 15

Step-by-step explanation:

Find slope (m) using of the line that passes through (7, 13) and (4, 1).

slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{1 - 13}{4 - 7} = \frac{-12}{-3} = 4

Find y-intercept (b) by substituting x = 4, y = 1, and m = 4 in y = mx + b.

Thus:

1 = (4)(4) + b

1 = 16 + b

Subtract 16 from each side

-15 = b

b = -15

substitute m = 4, and b = -15 in y = mx + b, to get the equation.

The equation of the line would be:

✅ y = 4x + (-15)

y = 4x - 15
