Answer:

A. three planes intersecting at a point

Step-by-step explanation:

Whenever three planes intersect at a point, then we have an ordered triplet (x,y,z) that is a solution to the associated system of equation.

This is a unique solution and it is finite.

However three planes intersecting at a line gives infinitely many solutions.

Three or two parallel planes may have no solution or or infinitely many solutions when they coincide.

Which of the following statements best describes the effect of replacing the graph of y = f(x) with the graph of y = f(x − 9)? T

egoroff_w [7]

Answer:

The graph of y = f(x) will shift to the right 9 units.

Step-by-step explanation:

Despite some lack of clarity, because usually this equality is in terms of x and y. Let's do it.

Taking f(x) as its parent function in other words

$y=f(x)$

Testing some values:

x|y

0|0

1|1

2|2

Adding to the function -9 units is to shift it to the right

$y=f(x-9)$

Testing some values to certify:

x|y

-9|0-9

-8|1-9

-7|2-9

Find the scale factor that was used to create the dilaton below

Ne4ueva [31]

Let:

$k\cdot IW=I^{\prime}W^{\prime}$

Where:

k = scale factor

IW = 12

I'W'= 8

so, solving for k:

$\begin{gathered} k=\frac{I^{\prime}W^{\prime}}{IW} \\ k=\frac{8}{12}=\frac{2}{3} \end{gathered}$

Which number is NOT in the solution set of x − 9 > 3?<br> A) 11 <br> B) 13 <br> C) 15 <br> D) 17

densk [106]

Answer:

Step-by-step explanation:

Given

x - 9 > 3 ( add 9 to both sides )

x > 12

13, 15 and 17 are all greater than 12

However, 11 is less than 12 and is not in the solution set → A

Answer:

emmainna [20.7K]

Let the numbers be n, n+2, n+4

Sum equals too= 13+2(n+4), which is 2n+21

a) Equation--> n+n+2+n+4= 2n+21

b) Solution--> 3n+6= 2n+21

=> n= 15

c) Second number--> 17 (15+2)

Third number--> 19 (15+4)

d) 15+15+2+15+4=30+21

=> 51= 51

So, the equation is true.

And pls mark me brainliesttt :)))
