Nonlinear, linear, nonlinear(Please excuse my grammar)

Step-by-step explanation:

A is nonlinear because it is an exponential function. As we add more X inputs, the change is the Y coordinates increase by a greater and greater amount. As an example, X=1, then Y=3, X=2, then Y=9, etc. B is linear because it is a horizontal line. No matter the X input, Y will remain the same because it is given: y=-5. C is nonlinear because it is a quadratic function. In any quadratic function, the line reaches a vertex before changing directions therefore, not forming a line.

question: The Honor Society sold tickets to the school dance. The number of tickets sold is recorded on the histogram below. How many students sold twenty or less tickets?

Answers

75
Explanation: because you have to look at the first 2 parts which are 1-10 & 11-20 which are both 20 or below and in the first one you have 40 and in the second one you have 35 so you add them both and get 75

the answer would be d, 75.

Total
50
Also, please explain your answer.

Answers

Answer:

Two dogs: 30%

Two cats: 20%

Two dogs OR two cats: 50%

Step-by-step explanation:

Since the total is 50, we have to multiply all the numbers by two. The total will then 100, so one unit in each category will represent one percent. For example, 15 x 2 = 30, so the chance for two dogs is 30%.

If your question meant two dogs OR two cats as a single probability - not the individual probabilities of two dogs and two cat - then it is 50%, because 30 (two dogs) + 20 (two cats) = 50 (two dogs OR cats).

Answer:

10x+40

Step-by-step explanation:

To solve you must follow these steps:

1. Multiply the outside (5) by the first number on the inside (2x) and you get 10x

2. Multiply the outside (5) by the second number on the inside of the parenthesis (8) and you get 40

3. You are left with 10x and 40, so your answer is 10x+40

Hope this makes sense, have a wonderful day!

answer: 10x+40

This is because you will divide 5 by 2x and the 5 by 8 so once you divided your answer should look like 10x+40

Answer:

Option 3 3 1/8x - 6 3/10

Step-by-step explanation:

(3 1/2x - 4 1/10) - (3/8x + 2 1/5)

Divide it into parts:

(3 1/2x - 3/8x) + (-4 1/10 - 2 1/5)

3 1/2x - 3/8x = 3 4/8x - 3/8x = 3 1/8x

-4 1/10 - 2 1/5 = -4 1/10 - 2 2/10 = -6 3/10

So we get:

solve for x.
Find solutions that are greatest to least.

Answers

6x^2 -18x -240=0 is a quadratic equation. Therefore you can use the quadratic formula to find ‘x’.

The greatest solution will be 8 and least solution will be -5.

A polynomial equation is given which is 6x² - 18x - 240 = 0

We have to find out the solutions that are greatest to least.

What do you mean by the quadratic equation ?

Quadratic equation is a polynomial equation whose highest degree is two . It is expressed in the form of ax² + bx + c = 0.

As per the question ;

Equation is ;

6x² - 18x - 240 = 0

Let's take 6 as common ;

6 ( x² - 3x - 40 ) = 0

x² - 3x - 40 = 0

This can be written as ;

x² - 8x + 5x - 40 = 0

x ( x - 8 ) + 5 ( x - 8 ) = 0

( x + 5 ) ( x - 8 ) = 0

x + 5 = 0

and

x - 8 = 0

So ;

x = - 5 and 8

Thus , the greatest solution will be 8 and least solution will be -5.

Find the value of x and m∠HKL.

Answers

Answer:

x = 25 degrees ∠HKL = 102 degrees

Step-by-step explanation:

The whole thing equals 180, since it is a straight angle

The value of HKL is 180 - 78 = 102

So that means 4x + 2 = 102

Subtract 2 from both sides:

4x = 100

Divide both sides by 4:

x = 25
