Answer:

C.

Step-by-step explanation:

A line is straight, and a segment is a part of a line.

A and D and lines because they have the arrows on the side, meaning they keep going and are not a segment.

B is not a line, it curves.

So that leaves C to be the answer because it is the only straight one with no arrows.

Answer:

[tex] \huge \boxed {29}[/tex]

Step-by-step explanation:

[tex]24 + |x - 4| - y[/tex]

Given x = 2 and y = -3. Therefore, substitute x = 2 and y = -3 in the expression.

[tex]24 + |2 - 4| - ( - 3) \\ 24 + | - 2| + 3[/tex]

Multiplying the negative with negative equal positive. All negative numbers in the absolute will become positive.

[tex]24 + 2 + 3 = 24 + 5 = 29[/tex]

Therefore the answer is 29.

Answer:

29

Step-by-step explanation:

Note that the absolute value function always give a positive value, that is

| - a | = | a | = a

Given

24 + | x - 4 | - y ← substitute x = 2, y = - 3 into the expression

= 24 + | 2 - 4 | - (- 3)

= 24 + | - 2 | + 3

= 24 + 2 + 3

= 29

Answer:

The measure of the larger is [tex]133^{\circ}[/tex].

Step-by-step explanation:

Given:

The measure of an angle is [tex]8[/tex] degrees less than three times the measure of another angle.

The two angles are supplementary.

To find: The measure of the larger angle.

Solution:

Let the measure of the smaller angle be [tex]x^{\circ}[/tex].

Then the measure of the larger angle be [tex]3x^{\circ}-8^{\circ}[/tex].

The two angles are supplementary, so their sum is [tex]180^{\circ}[/tex].

So, [tex]x^{\circ}+3x^{\circ}-8^{\circ}=180^{\circ}[/tex]

[tex]\Rightarrow 4x^{\circ}-8^{\circ}=180^{\circ}[/tex]

[tex]\Rightarrow 4x^{\circ}=180^{\circ}+8^{\circ}[/tex]

[tex]\Rightarrow 4x^{\circ}=188^{\circ}[/tex]

[tex]\Rightarrow x^{\circ}=\frac{188^{\circ}}{4}[/tex]

[tex]\Rightarrow x^{\circ}=47^{\circ}[/tex]

So, the measure of the smaller angle is [tex]47^{\circ}[/tex].

And, the measure of the larger angle is [tex]3\times47^{\circ}-8^{\circ}=133^{\circ}[/tex].

Hence, the measure of the larger is [tex]133^{\circ}[/tex].

Answer:

5(x+1)

Step-by-step explanation:

So factor is to make it simplified like x(y+c) {I made up random variable for an example but almost all factored problems look like this}

So first find the Greatest Common Factor or GCF for short

The GCF between 5x and 5 is 5

So you divide the whole thing by 5

5x+5/5

you’d get x+1

Now for the 5 just put it around X+1 but with parenthesis

5(x+1)

Answer:

Step-by-step explanation:

Answer:

1.000

Step-by-step explanation:

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

y-(-3+x)=0

STEP1:

Equation of a Straight Line

1.1     Solve   y-x+3  = 0

Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).

"y=mx+b" is the formula of a straight line drawn on a Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y-axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line  y-x+3 = 0 and calculate its properties

Graph of a Straight Line :

Calculate the Y-Intercept :

Notice that when x = 0 the value of y is -3/1 so this line "cuts" the y axis at y=-3.00000

 y-intercept = -3/1  = -3.00000

Calculate the X-Intercept :

When y = 0 the value of x is 3/1 Our line therefore "cuts" the x-axis at x= 3.00000

 x-intercept = 3/1  =  3.00000

Calculate the Slope :

The slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is -3.000 and for x=2.000, the value of y is -1.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of -1.000 - (-3.000) = 2.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

   Slope     =  2.000/2.000 =  1.000

Geometric figure: Straight Line

Slope = 2.000/2.000 = 1.000

x-intercept = 3/1 = 3.00000

y-intercept = -3/1 = -3.00000

Hope this helps!

Answer:

∠A=30°

Step-by-step explanation:

let's call the angle at the bottom B and the one next to the 130 C

∠A=3x-6

∠C=180-130= 50°

vertical angles are equal∠B =8x+4

∠A+∠C+∠B=180°

find x:

3x-6+50+8x+4= 180°

11x+48=180°

11x= 132

x=12

find ∠A

∠A=3x-6= 3(12)-6 =30°

Answer:

f=60 , c=30

Step-by-step explanation:

there are 2f and 2c in the graph and f=2c

So

f+f+c+c=180

2c+2c+c+c=180

6c=180

c=180/6

c=30

f=2c

f=2×30

f=60

If the measures of two complementary angles are in the ratio 7:3. The measure of the smaller and larger angle will be 27.02 and 62.9 respectively.

When two lines or rays converge at the same point, the measurement between them is called an "Angle."

It is given that, The measures of two complementary angles are in the ratio 7:3.

The angle is referred to as be complimentary angle when the total of two angles is 90 degrees. For instance, the angles of 30 degrees and 60 degrees complement one another.

Suppose the smaller angle is x and the larger angle is y,

x+y=90 -------(1)

If the measures of two complementary angles are in the ratio of 7:3.

y:x=7:3

7x=3y

y=7/3x

Substitute the value of y in equation 1 as

x+2.333x=90

3.333x=90

x=90/3.33

x=27.02

The measure of the smaller angle is 27.02. The measure of a larger angle is obtained as,

y=90-x

y=90-27.02

y=62.9

Thus, if the measures of two complementary angles are in the ratio 7:3. The measure of the smaller and larger angle will be 27.02 and 62.9 respectively.

Work Shown:

To find the average price, we will add up the 9 values in column 2 to get

120+272+358+328+406+392+530+592+610 = 3,608

Then divide that total by 9 since there are 9 values we added up

We get the average to be (3,608)/9 = 400.888 which is approximate. This rounds to 400.89

Side note: It's a bit strange how your teacher mentions "charge in pounds" but then uses a dollar sign.

Step-by-step explanation:

To find the mean, you add all the numbers together then divide by the number of numbers.

Charge : 120+272+358+328+406+392+530+592+610=3608/9=400.888888 =400.89 dollars

Answer:

180 cm³

Step-by-step explanation:

A glass is 1/3 full. Then 75cm³ of orange juice is poured in. The glass is now 3/4 full. What is the total volume of the glass?

Let

x = total volume of the glass

1/3x + 75 = 3/4x

75 = 3/4x - 1/3x

75 = 9x-4x/12

75 = 5/12x

x = 75 ÷ 5/12

x = 75 × 12/5

= 900/5

= 180 cm³

x = 180 cm³

Answer:

700 = 2² × 5² × 7

Step-by-step explanation:

We need to find 700 as a product of its prime factors in index form.

Prime factors of 700 =2 x 2 x 5 x 5 x 7

= 2² × 5² × 7

So, 700 is equal to 2² × 5² × 7.

Hence, 700 is expressed as a product of its prime factors in index form.
