Answer:

A. 4x² - 2x + 11

Step-by-step explanation:

(4x² + 6) - (2x - 5) =

Drop the first set of parentheses since it is unnecessary.

= 4x² + 6 - (2x - 5)

To drop the second set of parentheses, you must change every sign inside the parentheses.

= 4x² + 6 - 2x + 5

Now combine like terms.

= 4x² - 2x + 11

7.RP.A.1 3. If 1 1/2 cups of something fills 2/3 of a container, how many cups fill the container?

Andreas93 [3]

Answer:

Hi there!

Your answer is:

2 & 1/4 OR 2.25 cups fills the container!

Step-by-step explanation:

If 1 & 1/2 (aka 3/2) fills 2/3 of the container, then:

we know that half of 3/2s fills 1/3 of the container

To find half of 3/2, we multiply 3/2 by the inverse of 2, which is 1/2.

3/2÷2

3/2×1/2 = 3/4 ths

Now that we know 3/4ths fills 1/3 of the container, we add that to 1& 1/2.

3/4+ 1&1/2 = 2 & 1/4

Check your work!

3/4 × 3 should equal 2&1/4 if we are correct

3/4 × 3/1 = 9/4.

Simplify!

9/4 = 2&1/4

That tells us that we are correct!

Hope this helps!

What are the corresponding steps used to find the product of (2x+1)(x+1) ?

expeople1 [14]

You would distribute the 2x to the x and 1= 2x^2+2x
then you would distribute the 1 to the x and 1= 1x+1
then you would add it all together to get
2x^2+3x+1

I need help fast pleasee

trapecia [35]

Answer:

y = - cos ( $\frac{3}{4}$ x + $\frac{\pi }{4}$ )

Step-by-step explanation:

y = A cos ( Bx + C) + D

Vertical shift D = 0

A = - 1

Compression / Stretching B

Period of given function is $\frac{8\pi }{3}$

Period of cos x is 2π

$\frac{8\pi }{3}$ = $\frac{2\pi }{B}$ ⇒ B = $\frac{3}{4}$

Horizontal shift is C ÷ B

Horizontal shift of given function is $\frac{\pi }{3}$

$\frac{\pi }{3}$ = C ÷ $\frac{3}{4}$ ⇒ C = $\frac{\pi }{4}$

So, the equation of given function is

y = - cos (  $\frac{3}{4}$  x +  $\frac{\pi }{4}$  )

Assume f(x) = g(x). Which of the following pairsof functions may be used to represent theequation 3^x+^2 = 7x + 6?

Aloiza [94]

Functions and equations

We have that:

$3^{x+2}^{}=7x+6$

Let's name each side of it with f(x) and g(x):

Then, we have that:

$\begin{gathered} f(x)=3^{x+2} \\ \text{and} \\ g\mleft(x\mright)=7x+6 \end{gathered}$

Then, the answer is C
