Which of the following represents a function?
(-1, 2), (-2, 1), (-1, -2), (-2, -1)
(3, 4), (-3, 2), (3, 8), (5, 5)
(2, 3), (4, 3), (-2, -3), (-4, -3)
(5, 1), (5, 2), (5, 3), (5, 4)

Answers

Answer 1

Step-by-step explanation:

If in any set, you can find 2 or more points that lie on the same vertical,

then it is NOT a function, that is, the same value of x yields 2 or more different

values of y, you don't have a function.

e.g. D is definitely not a function. You have (-2,4) and (-2,-4) , the same x of -2 giving you a y value of 4 and -4.

*PLEASE HURRY WILL GIVE BRAINLY* A company's profits (in dollars) are modeled by the function p(x) = —x^2+ 1100x - 300000, where x is the number of units produced. To determine the minimum number

of units that must be produced in order to earn profits of $590, the company plots the parabola of y = —x^2 1100x -- 300000 and the line x = 590, finds the intersection

of the two, and concludes that 900 units must be produced. Is the company correct? Explain, rounding values to the nearest whole number if necessary.

Answers

No, it’s not correct. The y-axis on the graph represents the profits p(x) so the minimum number of units produced should be when the a horizontal line at y = 590 first intersects the parabola drawn left to right, and not a vertical line at x = 590 because that represents the profit as 590 units are produced.

Answers

Answer:

(write this in the format your curriculum suggests, most are different)

Since BC is longer than AB, this means m<bcd is smaller than m<bad.

A way to prove it mathematically is to look at the triangle on the left. Since It's an isosceles triangle, m<cda and m<dac are equal. However, the triangle on the right does not have two proven congruent sides. All we know is BC is larger than the other side lengths. In a figure like that, the obtuse angle that meets the longest side would be the largest angle.

A. 2x + 2y = 4.75
3x + y = 7.75

If 134n = 54eight , calculate n​

Answers

sorry what does 54eight mean?

The value of 'n' is approximately 4.0896.

To calculate the value of 'n' in the equation 134n = 548, we can isolate 'n' by dividing both sides of the equation by 134.

134n = 548

Dividing both sides by 134:

n = 548 / 134

Evaluating the division:

n ≈ 4.0896

Therefore, the value of 'n' is approximately 4.0896.

The simplified expression is 7x- 2.

What is Expression?

A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression. In a mathematical expression, the following terms are used:

An absolute numerical number is referred to as a constant.Variable: A symbol without a set value is referred to as a variable.Term: A term can be made up of a single constant, a single variable, or a mix of variables and constants multiplied or divided.Coefficient: In an expression, a coefficient is a number that is multiplied by a variable.

Given:

−4x−2y+6 from 3x−2y+4.

So, subtraction will be as follows

3x - 2y + 4-( -4x  -2y + 6 )

or, 3x - 2y + 4  + 4x + 2y -6

or, 7x - 2

Hence, the simplified expression is 7x- 2.

The 6 elephants at the zoo have a combined weight of 11,894 pounds. About how much does each elephant weigh?

Answers

Answer:

1982.33 pounds

Step-by-step explanation:

If they all weigh the same amount then you can figure it out by division.

11894/6=1982.33

Answer:

TO find out how much each elephant weighs you simply have to do 11, 894 divided by 6. Since the answer is a decimal (1982.33333333), I would just round it to the nearest tenth as it dosent specify where we have to round it to. SO, 1982.33333333 rounded to the nearest tenth is 1982.3

The school let out because the storm was arriving, and it didn't have a cellar big enough to hold all the students of Nopali School. Since most of them lived nearby, the school allowed them to go home before the storm hit. The students' cheers and whistles could be heard over the thunder and whirring winds that whipped through the schoolyard. August, for just one second, watched them all cheer in glee and wanted so much to join them, but instead, she began running. As August ran home, she could feel every step in her lungs. It felt like a hundred little lightning bolts shooting down her mouth and into her chest. She wanted to stop. She wanted to catch her breath. She even wanted to turn around to see if the clouds were chasing her down, but all she could think about was her family and her dog Mutton. She wanted to get to them desperately and hoped to see an abandoned house with all of them in the cellar in the backyard. Behind her, the wind whipped up every bit of gravel and dust into the air. The dust and debris filled the air and clouded the air like cream being stirred into a cup of black coffee. The sky looked like an antique picture. The once blue sky was now a sepia tone that August had only seen in old pictures. It was beautiful in a way, like some sort of painting. The only problem with tornadoes was that in addition to all of the beauty they painted in the sky, they also brought about destruction. In fact, August's school had been rebuilt twice because tornadoes had brought it down twice in the last 5 years. August remembered the desks splintered into two, looking like broken bones, the brass bell twisted and tangled like a ball of twine, the roof with holes the size of tractors. She knew first-hand how a tornado could bend a town until it broke. This knowledge is what kept her running. This knowledge is what made it easy to forget about the lightning in her lungs.
