Find the slope of the line passing through the points (-6,-5) and (4,4)

Answers

Answer:

m = [tex]-\frac{1}{10}[/tex]

Step-by-step explanation:

To find the slope you use the equation y2-y1 / x2 - x1. For this problem, it would be 4 - - 5/ 4 - - 6. If we simplify this you will get 9/10. Therefore, The slope of the line will be 9/10.

Relative Frequency
(A) 0.24
(B) 0.63
(C) 0.67
(D) 0.71
(E) 0.75

Answers

For the given table, the third quartile is given by:

(D) 0.71.

What are the median and the quartiles of a data-set?

The median of the data-set separates the bottom half from the upper half, that is, it is the 50th percentile.The first quartile is the median of the first half of the data-set, which is the 25th percentile.The third quartile is the median of the second half of the data-set, which is the 75th percentile.

Given a cumulative frequency table, the third quartile Q3 is the value when the sum of the frequencies is of 0.75.

From the frequency table, we have that:

A rate of 0.65 is the 30th percentile.A rate of 0.7 is the 57th percentile, as 0.3 + 0.27 = 0.57.A rate of 0.75 is the 80th percentile, as 0.57 + 0.23 = 0.8.

Hence the 75th percentile is between 0.7 and 0.75, meaning that option D is correct.

Maya spent her allowance on playing an arcade game a few times and riding the Ferris wheel more than once.

Write about what additional information you would need to create a two-variable equation for the scenario. What kind of problem could you solve with your equation?

HELP PLS

Answers

Answer:

Sample Response: To write a two-variable equation, I would first need to know how much Maya’s allowance was. Then, I would need the cost of playing the arcade game and of riding the Ferris wheel. I could let the equation be cost of playing the arcade games plus cost of riding the Ferris wheel equals the total allowance. My variables would represent the number of times Maya played the arcade game and the number of times she rode the Ferris wheel. With this equation I could solve for how many times she rode the Ferris wheel given the number of times she played the arcade game.

Hope this helps. :)

3x + 5 = 6x – 13
please please help!

Answers

Answer:

Simplifying

3x + -5 = 6x + -13

Reorder the terms:

-5 + 3x = 6x + -13

Reorder the terms:

-5 + 3x = -13 + 6x

Solving

-5 + 3x = -13 + 6x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-6x' to each side of the equation.

-5 + 3x + -6x = -13 + 6x + -6x

Combine like terms: 3x + -6x = -3x

-5 + -3x = -13 + 6x + -6x

Combine like terms: 6x + -6x = 0

-5 + -3x = -13 + 0

-5 + -3x = -13

Add '5' to each side of the equation.

-5 + 5 + -3x = -13 + 5

Combine like terms: -5 + 5 = 0

0 + -3x = -13 + 5

-3x = -13 + 5

Combine like terms: -13 + 5 = -8

-3x = -8

Divide each side by '-3'.

Movie tickets now cost seven dollars for adults over six years old. They cost six dollars a couple of years ago. What was the percent of increase?

Answers

Answer:

i think 3%

Step-by-step explanation:

Percent increase = (new value - initial value) / initial value
In this case, the new value is seven dollars, and the initial value is six dollars
So 7-6= 1. Divide by 6 will give u 0.16. The percentage increase is calculated by multiplying the answer by 100. So 0.16*100 = 16%. So 16% is the percentage increase.
In order to verify our answer. We find 16% of 6 and add it to 6. So 6 + 0.96 = 6.96 -> 7. So we are correct

f(x) = (x + 2)(2x^2 + 3)(x^2 + 4)

Evaluate f(x)=2x-7 when x=-2,0 and 3

Answers

Answer:

Step-by-step explanation:

A) y = 2x – 7  and f(x) = 7 – 2x

Incorrect. These equations look similar but are not the same. The first has a slope of 2 and a y-intercept of −7. The second function has a slope of −2 and a y-intercept of 7. It slopes in the opposite direction. They do not produce the same graph, so they are not the same function. The correct answer is f(x) = 3x2 + 5 and y = 3x2 + 5.

 

B) 3x = y – 2  and f(x) = 3x – 2

Incorrect. These equations represent two different functions. If you rewrite the first equation in terms of y, you’ll find the equation of the function is y = 3x + 2. The correct answer is f(x) = 3x2 + 5 and y = 3x2 + 5.

 

C) f(x) = 3x2 + 5 and y = 3x2 + 5

Correct. The expressions that follow f(x) = and y = are the same, so these are two different ways to write the same function: f(x) = 3x2 + 5 and y = 3x2 + 5.

 

D) None of the above

Incorrect. Look at the expressions that follow f(x) = and y =. If the expressions are the same, then the equations represent the same exact function. The correct answer is f(x) = 3x2 + 5 and y = 3x2 + 5.
