Answer:

y=2x-1

Step-by-step explanation:

y=mx+b

insert Point (0,-1)

m = 2

Y=2x-1 is the correct answer

the cost of 2 quesadillas and 3 burritos at a local mexican restaurant is $32. The cost of 4 quesadillas and 2 burritos at the same restaurant is $34. what is the cost of one quesadilla and 1 burrito?

Answers

It’s 7 each quesdilla and 6 burrito

Answer:

1 quesadillas is $4.75 and 1 Burrito is $7.50

Step-by-step explanation:

This question is a form of simultaneous equation

1. Quesadillas represents x and Burrito represents y

2. Form an equation base on the problem, hence as written below.

2x+3y=32

4x+2y=34

3. Use the elimination method by minusing the first equation from the second equation to give y=2x-2

4. Then you substitute the y=2x-2 into one of the equations above to find the x value. Eg y value substituted which is 2x+3(2x-2)=32. Therefore x=4.75

5. To find y substitute x value into either of the equation to find the y value.

Eg: 2(4.75)+3y=32. Therefore, make Y the subject to find Y value. Y= 7.50

An oil company drilled several wells. Fifty wells, or 25%, produced oil. What is the total number of wells that were drilled? *

A-50
B-100
C-125
D-200

Answers

Answer:

I think it's D

Step-by-step explanation:

because if

50 = 25%

100 = 50%

200 = 100%

I think it’s D because if you reread the question it says what is the total number, and D is 200 rather than C (125), I don’t think this helps but it’s a choice

7) Desserts Dessert Probability Cheesecake 4 20 Macaroons 1 5 Lava Cake 1 4 Banana Pudding 2 10 Lemon Squares 3 20 A restaurant chain conducts a random survey of sales of desserts to determine which desserts will be on a new menu. Based on the results of the random survey, which two statements are TRUE? A) MOST LIKELY, Lava Cake will be on the new menu. B) MOST LIKELY, Banana Pudding will not be the menu. C) MOST LIKELY, Lemon Squares will be on the menu. D) MOST LIKELY, Macaroons will not be on the menu. Eliminate E) MOST LIKELY, Lemon Squares will not be on the menu.

Answers

Answer:

can you write it more clearly? give me the amount of desserts then i can help

Step-by-step explanation:

Based on the results of the random survey, the two statements that are TRUE are given by: Option A: MOST LIKELY, Lava Cake will be on the new menu.

What does more likely means in terms of probability?

Probability of an event is the measurement of its chance of occurrence. The more the probability of an event is, the more likely it is to come as outcome as the result of the considered random experiment.

For this case, the probabilities for selection of each dessert based on its count's comparison with total counts are given as:

For cheesecake = 4/20For macaroons = 1/5 = 4/20For Lava cake = 1/4 = 5/20For Banana pudding = 2/10 = 4/20For lemon squares = 3/20

Thus, most likely dessert to be putted in the menu is with highest probability which is 5/20 which is for Lava Cake.

Answer:

B

Step-by-step explanation:

The answer is B.
There are 5 slots in the circle 100%/5 = 20%
There are 2 B’s and 2 A’s so each will equal 40% or 20%+20%
So 40%+40%= 80
SO C= 20%

A= 0.40
B=0.40
C=20

Here’s the answer. The sum of the 3 angles should be equal to 180. So you just have to add up all the 3 equations and set it equal to 180, and then solve for X. Then in each one of the equations you’re going to substitute X for the result that you got from before

You are standing at the top of the mountain 1,500 feet above sea level and your brother is a scuba diving in the ocean 10 feet below sea level. Write an expression using absolute values to determine the difference between the 2 positions.

Answers

Answer:

To find the absolute value remove abt negative sign in front of a number and to think of all numbers as a positive

Step-by-step explanation:

The expression using absolute values to determine the difference between the two positions is → d = x + |y| , where : x = +1500 and y = -10.

What are expressions?

A mathematical expression is made up of terms (constants and variables) separated by mathematical operators

Given is that you are standing at the top of the mountain 1,500 feet above sea level and your brother is a scuba diving in the ocean 10 feet below sea level.

For 1500 feet above the sea level, we can write -

{x} = + 1500 ft

For 10 feet below the sea level, we can write -

{y} = - 10

Assume the difference between the two positions is equal to {d}. So, we can write -

d = x + |y|

d = 1500 + |- 10|

d = 1500 + 10

d = 1510 ft

Therefore, the expression using absolute values to determine the difference between the two positions is → d = x + |y| , where : x = +1500 and y = -10.
