Answer:

(1) 4x + 28 (2) 18x- 27

Step-by-step explanation:

the first question 4(x + 7) can be simplified by multiplying the number outside the parenthesis (4) by both of the values inside:

4x + 28 or the last answer choice

in the second question you can use the same method:

9 (2x) = 18x

9 ( -3) = -27

therefore the correct answer choice is 18x - 27

hope this helps :)

P ( x ) = | x | and the image I ( x ) = 1 2 ⋅ P ( x ) graph

Ivan

Answer:

The picture where the red image is the skinniest

Step-by-step explanation:

The graph P(x) denotes the graph of the parent graph for all the functions. And, It includes the vertex of (0,0) and points which are shown below:

x f(x)

-2 2

-1 1

0 0

1 1

2 2

Now as we can see in the attached figure i.e it changed the function points i.e given below for l(x) = 12P(x)

x f(x)

-2 24

-1 12

0 0

1 12

2 24

This depicts that it has a skinner graph that includes redish graph

How many solutions does the following system have?

ale4655 [162]

Answer:

Option D. No solutions

Step-by-step explanation:

we have

$3x+2y=1$ -----> equation A

$-9x-6y=3$ ----> equation B

Multiply by -3 both sides equation A

$-3(3x+2y)=-3(1)$

$-9x-6y=-3$ -----> equation C

Compare equation B and equation C

Equation B and equation C are parallel lines with different y-intercept

Verify

For x=0

Equation C

$-9(0)-6y=-3$ -----> $y=0.5$

The y-intercept is the point (0,0.5)

Equation B

$-9(0)-6y=3$ -----> $y=-0.5$

The y-intercept is the point (0,-0.5)

therefore

Lines do not intersect

The system has no solution

see the attached figure to better understand the problem

I NEED HELP ON THIS PROBLEM PLS

dedylja [7]

Answer:

only A

Step-by-step explanation:

A is correct because if a number is less than 7, the number under the square root will be negative, and that will yield an imaginary (or non-real number)

B is incorrect because even if you choose a number less than 7, the result will still yield a real number

C is incorrect due to the same logic as B

D is incorrect because you can take the cube root of a negative number without it being non-real.
