a line has a slope of -3 and a y intercept of 5 write the equation of the line in slope intercept form and explain how you would use the slope and y intercept to graph the equation

Answers

Answer:

y = -3x + 5

First plot the y-intercept on the graph, then you go down/up based on the slope, in this case the slope is -3, so you go down three units and to the right 1 unit and then you will get your next point.

Jim and his friends are going to the Del Mar Fair and find they have two ticket options. In one option each person could buy an admission ticket for $5 and then pay $0.25 for each ride. The other option is to buy an admission ticket for $2 and then pay $0.75 a ride. What do you think Jim should do?

Answers

Step-by-step explanation:

let the cost of the options be y

since they are two already we can model the cost as

For the first ticket option

y=5+0.25(2)

y=5+0.5

y=$5.5

For the second ticket option

y=2+0.75(2)

y=2+1.5

y=$3.5

They should go for the second ticket option since it is $2 less than the first option

A video game store allows customers to rent games for $4.75 each. Customers can also buy a membership for $54 each year, and video games would then only cost $2.50 each to rent. Write and solve an equation to find the number of video games a customer would have to rent in a year in order for the two options to be equal.

Answers

Answer:

Step-by-step explanation:

Cost of membership + game = 2.50x + 54

Cost of just games = 4.75x

The catch is, how do we make up the 54 dollars?

So equate the 2 costs

4.75x = 2.50x + 54 Subtract 2.50

4.75x - 2.50x = 54 Combine

2.25x = 54 Divide by 2.25

x = 54/2.25

x = 24

That means that 24 is the break even point.

There are 15 circles and 12 squares. What is the simplest ratio of squares to total shapes?

Answers

4:5
They both divide by 3 so 12 divided by 3 is 4 and 15 divided by 3 is 5

The simplest ratio of squares to total shapes is 4 : 9.

The question wants the ratio to the total number of shapes so first find the total number of shapes:

= Circles + squares

= 15 + 12

= 27 shapes

There are 12 squares and 27 shapes. The ratio is therefore:

= 12 : 27

Use the lowest common factor of both numbers to find the simplest ratio. That factor is 3:

= [tex]\frac{12}{3} : \frac{27}{3}[/tex]

= 4 : 9

Answers

Wdym can you give more information x and y are both variables

Answer:

A coordinate system is a two-dimensional number line, for example, two perpendicular number lines or axes. The center of the coordinate system (where the lines intersect) is called the origin. The axes intersect when both x and y are zero. The coordinates of the origin are (0, 0).

5/6y-9=1/6y-5

What’s y

Answers

Answer:

y=4/6

Step-by-step explanation:

Step 1: Add 9 to both sides.

5/6y -9 = 1/6y -5

5/6y = 1/6y +4

Step 2: Subtract 1/6 to both sides.

5/6y= 1/6+4

y=4/6

If you are confused still, 5/6 - 1/6 is 4/6. Remember signs matter, because if the original equation was 5/6y -9 = -1/6y -5 the answer would be y= 4!

Round 685,135 to the nearest ten thousand.

Answers

I believe the answer is:

690,000

Answer:
690,000

Process:
685,135
In the ten thousands place is the number 8. To round to the nearest ten thousand, we have to look at the place value right behind it, the thousands place.

If the number in the thousands place is greater than or equal to 5, we round 8 up to 9. If the number in the thousands place is less than 5, we leave 8 as it is.

We can see that in the thousands place is the number 5, meaning that we round up to 9.
