Answer: The ratio is 18:3

Step-by-step explanation:

Answer:  6 to 1

Step-by-step explanation:

A ratio refers to a fraction. In this case the question asks how many players to coaches there are.

The word "to" means that is where the fraction bar goes.

Players/Coaches

There are 18 players and 3 coaches.

18/3

18 can be divided by 3, 6 times so the fraction can be simplified to

6/1 meaning there are 6 players for every coach.

Kevin goes to a restaurant that offers 4 appetizer choices, 4 different meats, 6 vegetables, 4 desserts, and 7 drinks. Assuming he gets one of each, how many different meals could he order? Responses A 184 B 25 C 2688 D 672 E 504

Answers

Kevin has 4 choices of appetizers, 4 choices of meats, 6 choices of vegetables, 4 choices of desserts, and 7 choices of drinks. To find the total number of different meals he can order, we need to multiply the number of choices for each category:

4 appetizer choices × 4 meat choices × 6 vegetable choices × 4 dessert choices × 7 drink choices = 2,688

Therefore, Kevin can order 2,688 different meals. So the answer is option C.
the correct answer is 2688 because if you do 4 x 4 x 6 x 4 x 7, it’ll equal to 2,688.

Which statements describe one of the transformations performed on f(x) = x^2
to create g(x) = -(x - 2)^2 +5?
O A. A reflection about the y-axis
B. A translation of 2 units to the left
c. A translation of 5 units up
D. A reflection about the x-axis

Answers

Answer:

The correct options are C and D

C. A translation of 5 units up

D. A reflection about the x-axis

Step-by-step explanation:

We have been given as function of the graph:

f(x) = x²

Which is transformed into the function

g(x) = -(x-2)² + 5

Consider the graph of y = x²

To convert it into the graph of given transformed function.

First reflect the graph over x-axis, the equation becomes

y = -(x)²

Then translate the graph 2 units to the right

y = -(x - 2)²

Then translate the graph 5 units up.

y = -(x - 2)² + 5

Thus, the correct statements are C and D

Help pls. Also wdym this is to short yk why so long >:/

Answers

Answer:

Y= mx + b

so Y = 1/3x + 2

just substitute

Due to the answer requesting slope intercept form, one shall use the points (3,2) in order to substitute for b. Slope intercept form is formatted in y = mx + b, which m would be your slope, which in this particular problem was given; therefore, y = 1/3x +b.


Now, we shall use points (3,2) as the substitutes for the solution for b, which 3 would be the input and 2 would be y.


Therefore, 2 = 1/3(3) + b
2 = 1 + b, therefore, one would be subtracted from 2 which would give us the answer of b equaling to one. Thus, y = 1/3x + 1
