7. f(x) = 2x + 5 What is the value of x if f(x) = 25 ?

Answer:

The least common multiply of 4 and 5 is 20.

Step-by-step explanation:

Answer:

Y = 2x + 4

Step-by-step explanation:

y= mx +b

First, find m (aka the slope)

[tex]\frac{rise}{run}[/tex] = [tex]\frac{2}{1}[/tex] = 2

m = 2

Find b (aka the y-intercept)

The line touches the y-axis at (0,4). Therefore b = 4

Plug m and b into the slope-intercept equation

y = mx +b

y = 2x + 4

Answer:

A

Step-by-step explanation:

The volume (V) of a cylinder is calculated as

V = πr²h ( r is the base radius and h the height )

Here r = 6 and h = 8, then

V = π × 6² × 8 = π × 36 × 8 = 288π cm³ → A

Karl traveled 420 kilometers by the time he had 200 liters of fuel remaining in his truck.

Why it is and what is distance?

To determine the distance Karl traveled by the time he had 200 liters of fuel remaining in his truck, we need to examine the graph provided.

From the graph, we can see that when the fuel remaining in the truck tank is 200 liters, the corresponding distance driven is approximately 420 kilometers.

Therefore, Karl traveled 420 kilometers by the time he had 200 liters of fuel remaining in his truck.

Distance is the physical length between two points or objects. It is a scalar quantity that measures the amount of space between two locations, without regard to the direction of travel. Distance can be measured in various units such as meters, kilometers, miles, and so on.

In physics, distance is often distinguished from displacement, which is a vector quantity that measures the change in position of an object relative to its starting point.

Answer:

30

Step-by-step explanation:

Answer:

1.) B.) 30

2.) D.) 2.38

Step-by-step explanation:

1.) The answer is B because when the encyclopedia first went live there were 30 articles in it.

2.) The answer is D because the product first started out as $38⁰⁰ and each year it is decreasing half the amount of the year before it and it does this for 4 years:

Start:         Year 1:     Year 2:      Year 3:      Year 4:

$38⁰⁰ ÷ 2 = $19 ÷ 2 = $9⁵⁰ ÷ 2 = $4⁷⁵ ÷ 2 = $2³⁸ <--- I rounded up because 2.375 is closer to 2.38

Answer:

you will eliminate the y variable

Step-by-step explanation:

Answer:

True

Step-by-step explanation:

An asymptote is, essentially, a line that a graph approaches, but does not intersect. For example, in the following graph of y = 1x y = 1 x , the line approaches the x-axis (y=0), but never touches it. No matter how far we go into infinity, the line will not actually reach y = 0, but will always get closer and closer.

The statement is true.

Asymptote is a line that a curve approaches as it moves towards infinity. Asymptotes. The curves visit these asymptotes but never overtake them.

An asymptote is a line along which the values of a function approaches but never reach, such that one or both of the or coordinates tend to positive or negative infinity. Therefore, the graph of a rational function never intersects any of its asymptotes.

Hence, the statement is true.

Answer: -2

Step-by-step explanation:

Answer:

You have to write the number-line out man. However, the answer is -2

Step-by-step explanation:

When solving problems like these, knowledge or integers and whole numbers are important. First, find the absolute values of both numbers.

Absolute value of -6: 6

Absolute value of 4: 4

Subtract the values: 6 - 4 = (Positive 2)

THEN, look at the number with the Greater Absolute value. In this case, it is -6. Because -6 has the greater absolute value, your answer should be the connotation of that number. IN THIS CASE, the number with the greater absolute value, -6, has a negative sign. Therefore, your answer should be negative. Your answer is -2.

Arc KL [tex]=23[/tex]

Arc OM [tex]=113[/tex]

Step-by-step explanation:

We know that Angle NPM is equal to 90 degrees.

Therefore, Angle KPM is also equal to 90 degrees.

We are told that Arc LM is equal to 67.

Thus, the measure for Arc KL is equal to [tex]90-67=23[/tex]

We also know that Angle OPN is equal to Angle KPL.

Therefore, the measure of Arc ON[tex]=23[/tex]

Using that information, we know that Arc OM is equal to [tex]90+23=113[/tex]

Answer:

57 dollars

Step-by-step explanation:

1. Solving the 25% discount

25% = .25

80 x .25 = $20

80 - 20 = $60

** We subtracted 80 from 20 because 25% of 80 is 20 BUT We're taking 25% OFF of 80 because it was a discount.

2. Solving the 5% Tax

5% = .05

$60 x .05 = 3

$60 + 3 = $63

**Adding tax to the discounted price

Answer:

Courtney is bringing 8 snacks

Step-by-step explanation:

Chelsea's snacks are represented as 2x.

2x means 2 · (a number)

If Chelsea brought 16 snacks and the amount of snacks represented by 2x, we have to figure out what times 2 equals 16.

In order to find out, we have to divide.

16 ÷ 8 = 2

This means 2 · 8 = 16

Since the amount of snacks Courtney brings is represented as "x", she would have brought 8 snacks.

Hope this helped! :)

Answer:

Angle 1 is 58 and Angle 2 is 32 because all triangles equal to 180 and where the lines bisect creates a 90 degree angle in each triangle. Add 90 and 32 together, then minus 122 from 180 and you get angle 1 and the angle across from angle 1. For angle 2, add 58 and 90, then subtract that from 180. You'll end up getting 32

Answer:

x=10

Step-by-step explanation:

Simplifying

1.5x + 3 = 18

Reorder the terms:

3 + 1.5x = 18

Solving

3 + 1.5x = 18

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3' to each side of the equation.

3 + -3 + 1.5x = 18 + -3

Combine like terms: 3 + -3 = 0

0 + 1.5x = 18 + -3

1.5x = 18 + -3

Combine like terms: 18 + -3 = 15

1.5x = 15

Divide each side by '1.5'.

x = 10

Simplifying

x = 10
