Answer: y = 4x - 11

Step-by-step explanation:

The point (0, 0) is not lie on the graph of this step function.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The fee for charging an electric car at station A is $2 to start and $4 for each hour or fraction of an hour.

Now,

Since, The fee for charging an electric car at station A is $2 to start and $4 for each hour or fraction of an hour.

Hence, We can formulate the function as;

⇒ y = 4x + 2

Substitute (x, y) = (0, 0), we get;

⇒ y = 4x + 2

⇒ 0 = 4 × 0 + 2

⇒ 0 ≠ 2

Thus, The point (0, 0) is not lie on the graph of this step function.

Answer:

x = 3 and x = -12

Step-by-step explanation:

To solve an absolute value equation, you create two equations, one where the right side is negated and one where the right side isn't:

| 2x + 9 | = 15 becomes:

2x + 9 = 15 and 2x + 9 = -15

2x = 6 and 2x = -24

x = 3 and x = -12

Why this works is that |-x| and |x| will both be equal to 0. Remember that absolute value is the distance a number is away from 0.

Answer:

finding slope: The slope will be the same for a straight line no matter which two points you pick as you know. All you need to do is to calculate the difference in the y coordinates of the 2 points and divide that by the difference of the x coordinates of the points(rise over run). That will give you the slope.

parallel: We can determine from their equations whether two lines are parallel by comparing their slopes. If the slopes are the same and the y-intercepts are different, the lines are parallel. If the slopes are different, the lines are not parallel. Unlike parallel lines, perpendicular lines do intersect.

hope this helps!

Answer:

The slope of a line is the rise/run of how far away the points are from each other. Say you have the equation y=3/4x-6, the slope is 3/4 so that means you plot your first point at -6 on the y-axis, because that is your y-intercept, and then you will go up 3, right 4. You will continue to do this until you have enough points to make a line. When two lines are parallel, they will always have the same slope. So the lines y=1/2x+4 and y=1/2x-3 are parallel because not only do they have the same slope, they do not intersect at all, which is a requirement for parallel lines. I hope this helps!!

Answer:

⁴√16³ˣ

Step-by-step explanation:

16³/⁴ ˣ

The above can be expressed as follow:

16³/⁴ ˣ = 16³ˣ/⁴

Recall:

Aᵐ/ⁿ = ⁿ√Aᵐ

Therefore,

16³ˣ/⁴ = ⁴√16³ˣ

Thus, 16³/⁴ ˣ is equivalent to ⁴√16³ˣ

Answer:

-19/9

Step-by-step explanation:

First, you would plug in the numbers for y and r. Therefore, your equation should now be 5 = 9x + 24. Now you would put like terms on the same side. It now then look like -19 = 9x. You divide by 9 to get the x by itself. The answer should be x = -19/9.

Answer:

Step-by-step explanation:

a) PQ' / PQ = 12/8 = 3/2

  Q'R' / QR = 15/10 = 3/2

  PR' / PR = 9/6 = 3/2

b) this means that triangle PQR is congruent to triangle PQ'R'. Because if we divide each side we get 3/2 (SSS)

c) because QR and Q'R' are parallel and they have same angles.

Answer: 72 ft^3

Step-by-step explanation:

When you fill the box with cubes you can plug in the numbers. The volume formula is length times width times height. With those cubes filled in the box the length is 3 the width is 6 and the height is 4. 3 times 6 times 4 is 72. I don’t know if it’s right but that’s what I think.

Answer: 18^3

Step-by-step explanation:

Once you find the volume (72) you have to multiply by 1/4 which makes it 18^3 ft - the guy above is wrong tbh

Answer: 6y=13.5

Step-by-step explanation:

just multiply 6 by 2.25

Answer:

y = [tex]\frac{3}{8}[/tex]

Step-by-step explanation:

Given

6y = 2 [tex]\frac{1}{4}[/tex] ← change into an improper fraction

6y = [tex]\frac{9}{4}[/tex] ( multiply both sides by 4 to clear the fraction )

24y = 9 ( divide both sides by 24 )

y = [tex]\frac{9}{24}[/tex] = [tex]\frac{3}{8}[/tex]

Answer: 1/4

Answer:

2y - 5 (read below)

Step-by-step explanation:

-8y + 10y = 2y

2 + (-7) = -5

Your expression could/would be:

2y - 5.

Hope this helps!

Answer:

you can combine -8y and 10y since 8 is negative it would be =2y

an you can do 2+-7=-5

Answer:2 1 4 then 3

Step-by-step explanation:

The option (3) 0.03, 0.3, 0.35 represents the order from least to greatest. Option (3) is correct.

A number is a mathematical entity that can be used to count, measure, or name things. For an example, 1, 2, 56, 0.3 etc. are the numbers.

We have decimal number:

0.35, 0.3, 0.03

Here, the smallest number is 0.03

And the greatest number is 0.35

So,

The order from least to greatest:

0.03 > 0.3 > 0.35

Thus, the option (3) 0.03, 0.3, 0.35 represents the order from least to greatest. Option (3) is correct.

Answer:

$17.65

Step-by-step explanation:

First you have to subtract $7.65 from the total cost, $42.95.

Now, you have $35.30. Since she bought 2 DVD's, you have to divid $35.30 by 2.

Your answer is now $17.65, meaning that each DVD cost $17.65.

Answer:

  (f×g)(2) = 3/4

Step-by-step explanation:

For each of the functions, put 2 where x is and evaluate the expression.

  f(2) = (3 -2)/(2² +4) = 1/8

  g(2) = 3×2 = 6

Then the product is ...

  (f×g)(2) = f(2)×g(2) = (1/8)×6 = 6/8

  (f×g)(2) = 3/4

Answer:

slope = [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y= intercept )

Given

2y - x = 4 ( add x to both sides )

2y = x + 4 ( divide all terms by 2 )

y = [tex]\frac{1}{2}[/tex] x + 2 ← in slope- intercept form

with slope m = [tex]\frac{1}{2}[/tex]
