Answer:

D. 2x^2 - 2x + 2

Step-by-step explanation:

(3x2 – 2x + 5) – (x2 + 3) add or subtract like terms

3x^2 - x^2 - 2x - 3 + 5 = 2x^2 - 2x + 2

3.) Write an inequality for the phrase "two more than three times a number is at
stiks02 [169]

Answer:

3x + 2 ≤ 53

Step-by-step explanation:

"2 more than" means that there will be a + 2 in the equation. "3 times a number" means that 3 is multiplied by an unknown number which can be represented by a variable such as x. "At most" means less than or equal to, since the number cannot be greater than.

So generally, you might want to write the equation as 2 + 3x ≤ 53, but 2 + 3x is not in y = mx + b form. Basically, you need to write it as 3x + 2 ≤ 53 because that's how math works.

Play room is 9 pounds of apples she needs 1 1/4 pounds to make one apple pie if she set aside 1.5 pounds of apples to make apple
kumpel [21]
Hi there!

I'm unsure if '11/4 pounds' meant '1/4', however, if it did, the answer is 6 pies in total.

Here's how I worked it out:
9 - 1.5 = 7.5 ( 1 )
7.5 - 1.5 = 6 ( 2 )
6 - 1.5 = 4.5 ( 3 )
4.5 - 1.5 = 3 ( 4 )
3 - 1.5 = 1.5 ( 5 )
1.5 - 1.5 = 0 ( 6 )

<em>Hope I helped! (:</em>

The graph of f(x) = 2x. The graph of g(x) = ()x is the graph of f(x) = 2x reflected over the y-axis. Which graph represents g(x)
AfilCa [17]

For this case we have transformation of functions:

Reflection is the mirror image of a figure. It can also be defined as the turning of points and graphs around the axes.

So, we have:

To graph y = f (-x), the graph of y = f (x) is reflected on the y-axis. (Horizontal reflection)

If f (x) = 2x, to obtain g (x) as a horizontal reflection, we evaluate

g (x) = f (-x)

Thus:

g (x) = f (-x) = 2 (-x)g (x) = - 2x

Answer:

g (x) = - 2x
