Max car holds 18 gallons of gasoline driving on the highway the car uses approximately 2 gallons per hour. let H represent the number of hours max has been riding on the highway. write an expression that shows how many gallons of gasoline Max has left after driving H hours. then find the number after max drives 3.5 hours on the highway.

Answers

y= 18 gallons-2(h)
y is what you're trying to find out and since there are 18 gallons in the tank after every hour you would have 2 less gallons. So, you can multiply how many hours he's been driving by the 2 gallons and subtract it from 18

Answer:

21 square feet

Step-by-step explanation:

To find out the area of this irregular figure, divide it into two rectangles and add their areas.. This can be done in two ways.

Version 1: 6 * 2 rectangle and 3 * 3 square

(6 * 2) + (3 * 3)

12 + 9

21 sq. ft.

Version 2: 5 * 3 rectangle + 2 * 3 rectangle

(5 * 3) + (2 * 3)

You could really just do 7 * 3 here.

7 * 3

21 sq. ft.

Either way, you still get 21 square feet as your answer.

Which expression has the same value as 8 – (-1)?

Answers

Answer: 9

Step-by-step explanation:

Two negatives make a positive. So the expression 8-(-1) is equal to 9, because the two subtraction signs the equation create an addition sign, and the equation becomes 8 + 1.

Therefore, 9 has the same value as 8-(-1).

-15=3x divide by 3 on both sides

Which of the following equations are equations of a direct variation? Choose all that apply.
(a) x=−2y
(b) x+2y=12
(c) 3x−2y=0
(d) 5x^2+y=0
(e) y =0.3x +1.6
(f) y−2=x

Answers

Answer:

(a) x = -2y

Step-by-step explanation:

You can tell if an equation is a direct variation equation if it can be written in the format y = kx.

Note that there is no addition and subtraction in this equation.

Let's put these equations in the form y = kx.

(a) x = -2y

y = x/-2 → y = -1/2x This is equivalent to multiplying x by -1/2, so this is an example of direct variation.

(b) x + 2y = 12

2y = 12 - x y = 6 - 1/2x This is not in the form y = kx since we are adding 6 to -1/2x. Therefore, this is NOT an example of direct variation.

-2y = -3x y = 3/2x This follows the format of y = kx, so it is an example of direct variation.

(d) 5x² + y = 0

y = -5x²This is not in the form of y = kx, so it is NOT an example of direct variation.

(e) y = 0.3x + 1.6

1.6 is being added to 0.3x, so it is NOT an example of direct variation.

(f) y - 2 = x

y = x + 2 2 is being added to x, so it is NOT an example of direct variation.

The following equations are examples of direct variation:

x = -2y 3x - 2y = 0

Answer:

(a) x = -2y

Step-by-step explanation:

You can tell if an equation is a direct variation equation if it can be written in the format y = kx.

Note that there is no addition and subtraction in this equation.

Let's put these equations in the form y = kx.

(a) x = -2y

y = x/-2 → y = -1/2x

This is equivalent to multiplying x by -1/2, so this is an example of direct variation.

(b) x + 2y = 12

2y = 12 - x

y = 6 - 1/2x

This is not in the form y = kx since we are adding 6 to -1/2x. Therefore, this is NOT an example of direct variation.

-2y = -3x

y = 3/2x

This follows the format of y = kx, so it is an example of direct variation.

(d) 5x² + y = 0

y = -5x²

This is not in the form of y = kx, so it is NOT an example of direct variation.

(e) y = 0.3x + 1.6

1.6 is being added to 0.3x, so it is NOT an example of direct variation.

(f) y - 2 = x

y = x + 2

2 is being added to x, so it is NOT an example of direct variation.

The following equations are examples of direct variation:

x = -2y

3x - 2y = 0

There are 7 ted marbles. 7 blue marbles, and 7 green marbles.If a person randomly selects 1 marble from the bag, what is the probability that the person selects a blue marble.

Answers

Answer:

there are an equal amount of all three colors of marbles in the bag, so the probability of selecting a blue marble is just 1/3.

Let me know if this helps!

1/3
There is 21 marbles and if you divided by 3 it gets 7.

7/21 is equal to 1/3

Therefore the possibility of picking a blue marble is 1/3.

Step-by-step explanation:

Common Ratio of a Geometric sequence, R is calculated as

=a2/a1 = -40/100=-0.4

or a3/a2=16/ -40 = -0.4

such that the next three terms are

5th term = -6.4 x -0.4=2.56

6th term= 2.56 x -0.4 =-1.024

7TH term= -1.024 x -0.4=0.4096
