Answer:

The correct answer option is D. (x - 7) + 2.

Step-by-step explanation:

We are to determine whether which of the given options best describe the English expression:

'two more than the quantity of a number minus seven'

We can break this expression into smaller chunks to make it easier to translate.

1. two more than ---> +2

2. the quantity of a number ---> suppose the number to be 'x'

3. number minus 7 ---> (x - 7)

Combining these, we get (x - 7) + 2 so the correct answer option is D.

<h2>Answer:</h2>

The correct option is (D) x-7 + 2

<h2>Step-by-step explanation:</h2>

let the quantity be x

Quantity minus 7 can be written as

x-7

Now

2 more means adding 2

So the final expression can be written as

(x-7) + 2

Please help I asked this question earlier and nobody answered! :(

Answer:

Step-by-step explanation:

One way to tell is to put both equations into slope-intercept form. That form is usually written $y=mx+b$ where m is the slope and b is the y-intercept.

Solve the first equation for y.

$6x+2y=5 \\ 2y=-6x+5 \\ y=-3x+5/2$

The slope of this line is -3, and its y-intercept is 5/2.

Solve the second equation for y.

$y+3x=2\\y=-3x+2$

The slope of this line is -3 and its y-intercept is 2.

The lines are parallel because they have the same slope and different y-intercepts. There is no solution to the system.

Describe the transformation from y= x + 4 to y= .5x + 4 Group of answer choices compresses stretches shifts right 4 shifts left

Nina [5.8K]

Answer:

This type of transformation is a horizontal stretch.

Step-by-step explanation:

Given

$y = x + 4$

$y = .5x + 4$

Required

Determine the type of transformation

The first function can be expressed as:

$f(x) = x + 4$

While the second function is:

$g(x) = f(0.5x)$

Solving f(0.5x), we have to substitute 0.5x for x in $f(x) = x + 4$

$f(0.5x) = 0.5x + 4$

So:

The second function is:

$g(x) = 0.5x + 4$

This type of transformation is a horizontal stretch.

i.e. f(x) stretched to g(x)

F(x) = 2x2 – 15 Find f(-2)

bogdanovich [222]

Wherever you see an x, replace it with -2,
So f(-2) = 2(-2^2) -15
= (2x4)-15
= -7
