Hello : let

A(5,22) B(2,13)

the slope is : (YB - YA)/(XB -XA)

(13-22)/(2-5) = -9/-3

an equation is : y=ax+b a is a slope

y = 3x +b

the line through point A (5,22) :

22 = 3(5)+b

b = 7

the equation is : y =3x+7

Y = mx + b

Find m first

m = 22 - 13 / 5-2
m = 9/3
m = 3

find b

Y = 3x + b

Substitute for x and y coordinates

13 = 3(2) + b

13 = 6 + b

7 = b

Y = 3x + b

In the function f(x) = 4(x2 − 6x + ____) + 20, what number belongs in the blank to complete the square?

grandymaker [24]

The right answer for the question that is being asked and shown above is that: In the function f(x) = 4(x2 − 6x + ____) + 20, what number belongs in the blank to complete the square?

x2 - 6x + 9

So the answer on the blank space is 9. It should be a perfect square.
= 6/2
= 3^2
= 9

Zander was given two functions: the one represented by the graph and the function f(x) = (x + 4)2. What can he conclude about th

Svetradugi [14.3K]

The conclusion about the functions is they have the same y-intercept.

<h3>How to make conclusion about the functions?</h3>

The complete question is added as an attachment

The function is given as:

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

From the attached graph, the graph has a y-intercept at:

y = 16

This can be represented as:

(0, 16)

Next, we set x = 0 in f(x) = (x + 4)^2

f(0) = (0 + 4)^2

Evaluate

f(0) = 16

This means that the y-intercept of f(x) = (x + 4)^2 is (0, 16)

So, the functions have the same y-intercept

Hence, the conclusion about the functions is they have the same y-intercept.
