Answer:

(2x - 4)(2x + 7) = 4x^2 +14x - 8x -28

= 4x^2 + 6x -28

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

(4x^2 + 6x - 28) - ( x^2 + 3x ) = 3x^2 + 3x -28

Which function has the same graph as x + y= 11?

leonid [27]

Answer:

f(x) = 11 - x

Step-by-step explanation:

We have to find a function that has a graph as x + y = 11.

Now, the equation given is

x + y = 11

⇒ y = 11 - x

So, if we consider x as an independent variable and y as a dependent variable whose values are dependent on the values of x, then er can write y = f(x) = 11 - x

So, the function f(x) = 11 - x has the same graph as x + y = 11. (Answer)

THE CORRECT ANSWER WILL GET BRANLIEST

zheka24 [161]

Answer:

k=11

Step-by-step explanation:

Slope is calculated by dividing the change in y over the change in x. The change in x for these points is 4. This leaves us with y/4 as the slope, which must equal 2. Divide both sides of the equation (y/4=2) by 4. y=8

Now add 8 to the y coordinate of (1,3) in order to get a y value of 11 for the second coordinate.

The data set below shows prices for concert tickets in 10 major cities. Find the interquartile range (IQR) of the set. How do t

Llana [10]

Answer: IQR = 16

Step-by-step explanation:

Given the following data:

Cost of concert :

CITY : Q, R, S, T, U, V, W, X, Y, Z

Price : 35,36,42,38, 24,29,25, 44,49, 26

Interquartile range (IQR) = Q3 - Q1

Where,

Q3 = the upper quartile

Q1 = lower quartile

Rearranging the data:

24,25,26,29,35,36,38,42,44,49

Q3 = 42

Q1 = 26

IQR = (42 - 26) = 16
