Step-by-step explanation:

Use the slope formula so y2 - y1 / x2 - x1 [the numbers are subscripts]  

So -8 - (-3) / -2 - (-6) so -8+3/-2+6, therefore -5/4

The Vincent family played a game of basketball. For each game, Ben kept a record of the number of 2-point baskets he attempted, and the number of 3-point baskets he attempted. After the family played several games, he made a scatter plot of the data using the 2-point shots as the x-variable and the 3-point shots as the y-variable. The scatter plot has a line of best fit with the equation y=1.2x+3.1

A pizza with a diameter of 8 inches costs $10 and a pizza
with a radius of 5 inches costs $12. Which pizza is the
best buy (square inches per dollar)?

Answers

Answer:

8 inch is your best buy

Step-by-step explanation:

8inch diameter =10 dollars

5 inch radius = 12 dollars

so if we get each equal to the diameter it should be 10 inch and that would be 24 dollars vs . 8 in for 10 dollars. So best buy would be 8 inch

Two hamsters work together and move a pile of sunflower seeds in 7 1 2 minutes. How long would it take each hamster to move the same pile alone if one of the hamsters needs 8 more minutes to do the job than the other?

Answers

Answer:

Hamster 1: 12 minutes. hamster 2: 20 minutes

Step-by-step explanation:

The first hamster took 8 minutes while the second hamster tool 20 minutes.

Equation

An equation is an expression used to show the relationship between two or more numbers and variables.

Let x represent the time required for the first hamster and y the time for the second hamster.

x = y + 8    (1)

(1/x + 1/y)7.5 = 1

[1/(y + 8) + 1/y ]7.5 = 1

y = 12 minutes

x = 12 + 8 = 20 minutes

The first hamster took 8 minutes while the second hamster tool 20 minutes.

Describe fully the single transformation which takes shape A to shape B

Answers

Answer:
The single transformation that maps shape A onto shape B is a reflection across the line y = 2
Step-by-step explanation:
The coordinates of the A are A(-1, 3)
The coordinates of the corresponding point on B is (-1, 1)
Therefore, given that the x-coordinates of the pre-image A and the image B are the same, therefore, we have that image B is a reflection of image A
Also half the vertical distance between figure A and B = (3 - 1)/2 = 1
Therefore, figure A is obtained from figure B by reflection across a horizontal line, 1 unit below the lowest y-coordinate of figure A which is the line y = 3 - 1 = 2
Therefore, we have;
The single transformation that maps shape A onto shape B is a reflection across the line y = 2

You recycled a total of 30 cans and bottles and made $1.80. For cans you get $0.05 and for bottles
you get $0.15. How many cans did you recycle?

Answers

Answer:

27

Step-by-step explanation:

x + y = 30

0.05x + 0.15y = 1.80

x = 30 - y

1.5 - 0.05y + 0.15y = 1.80

0.10y = 0.30

y = 3 (bottles)

x = 27 (cans)

a coin is tossed 200 times, if the probability of getting a head is 5/8, how many times tail is obtained in all in tossing the coin?
​

Answers

Answer:

You would get tails 75 times, or 75:200

Step-by-step explanation:

5:8 = x:200

multiply 8 by 25 to get 200

multiply 5 by 25 to get x (125)

Probability to get heads is 125 so subtract 200 by 125

200 - 125 = 75
