Answer:

C. -2, 1, 1, and 3 only

Answer: Below

Step-by-step explanation:

24% is basically 0.24. Since we want to find the original price we make the equation:

x * (1 - 0.24) = 665

For x is the original price. Simplify:

x * (0.76) = 665

x = 665/0.76

x = 875

Our answer is 875

Answer:

3.50= 1x + i dont know B

Step-by-step explanation:

the equation is y=mx + b

The equation in slope-intercept form to model the cost in dollars, y, for x refills is 3.50= 1x + b.

An equation is an expression that shows the relationship between two or more numbers and variables.

We have been given that movie theater sells popcorn in a reusable bucket for $3.50. They offer refills for $1.00 each.

The value of y  is popcorn cost = $3.50

The slope will be $1.00

Therefore, the equation is y=mx + b

Plug the values;

3.50= 1x + b

Hence, the equation in slope-intercept form to model the cost in dollars, y, for x refills is 3.50= 1x + b.

Answer:

y=5

Step-by-step explanation:

9y+6 = 3y+3+7+26

arrange the equation so all values with y are on one side, and all regular numbers are on the other side. Make sure you change the sign when changing sides.

9y - 3y = 3 + 7 + 26 -6

6y / 6 = 30 / 6

Now divide both sides by 6 in order for y to be alone.

y = 5

Answer: 9:4

Step-by-step explanation: Total is 30. Add 18 and 4 to see how many students were already surveyed, (22) and then subtract that from 30. Then you get 8, so the ratio is 18:8. Then simplify by dividing both numbers by 2, so you get 9:4. Hope that helps :)

Answer:

y = 4/5 x - 2

Step-by-step explanation:

Find for slope first:

m = (y2 - y1) / (x2 - x1)

= [(-6) - 2] / [(-5) - 2]

= -8/-10

= 4/5

Solve for b. Use (5, 2)

y = mx + b

2 = 4/5 (5) + b

2 = 20/5 + b

2 = 4 + b

2 - 4 = b

-2 = b

Substitute the value of m and b.

y = mx + b

y = 4/5 x + (-2)

y = 4/5 x - 2

Answer:

39 visits.

Step-by-step explanation:

In order to solve, we must add the cost of the membership and the cost of the visits to get the sum of 46.

$7 is the cost of the membership, so thats going to be the first number we add. If you revist the museum, you will need to pay $1. Now to save time and space, I will not continusely write $1 until we get to 46, but instead, subtract 46 from 7. The difference we get will be the number of visits. I will be using the variable v to represent the difference/maximim number of visits a member of the science museum can make for a total cost of $46.

Current Equation: 7+1v = $46.

46 - 7 = 39.

7+1(39) = 46

I agree with the previous answer. It indeed is 39.

46-7=39 (7 - price of the membership)

39/1=39 (1 - price of the tickets)

Answer:

C on edg

Step-by-step explanation:

[tex]y = - \frac{4x}{9} + 3[/tex]

Move the expression to the left-hand side and change its sign

[tex]y + \frac{4x}{9} = 3[/tex]

Multiply both sides of the equation by 9

[tex]9y + 4x = 27[/tex]

Use the commutative property to reorder the terms

[tex] \underline{ \underline{4x + 9y-27 = 0}}[/tex]

Standard form of a line:-

[tex]\\ \rm\Rrightarrow y=\dfrac{-4x}{9}+3[/tex]

[tex]\\ \rm\Rrightarrow y=\dfrac{-4x+27}{9}[/tex]

[tex]\\ \rm\Rrightarrow 9y=-4x+27[/tex]

[tex]\\ \rm\Rrightarrow 4x+9y-27=0[/tex]
