Answer:

x=50

Step-by-step explanation:

Since Line AB and Line CD are parallel, Angle AFG is supplementary to Angle CGF. So then x+3x-20=180. Then you just solve for x.

Combine like terms-> 4x-20=180

Add 20 to both sides-> 4x=200

Divide both sides by 4-> x=50

Hope this helps!

Feel free to ask if you still don't understand something

Is 3a + 3B equivalent to 3 (a + 2B) <br>true or false

natulia [17]

Hi there!

»»————-　★　————-««

I believe your answer is:

The expressions given are not equivalent.

»»————-　★　————-««

Here’s why:

We can check if the expressions are equivalent by simplifying one of them.

⸻⸻⸻⸻

$\boxed{3(a+2B)}\\\\---------\\\rightarrow3*a = 3a\\\\\rightarrow3 * 2B = 6B\\\\\text{Therefore:}\\\\3(a+2B)=\boxed{3a+6B}\\\\\text{and}\\\\\boxed{3(a+2B)\neq 3a+3B}$

⸻⸻⸻⸻

You can also say that they are not equivalent because it was not completely distributed.

Hope this helps you. I apologize if it’s incorrect.

Given f(2) = 12, which of the following could be an equation of the function?

Viktor [21]

The equation of the function would be:
B. f(x)=4x+4, because if x=2, and if the answer is 12, 12 divided by 2 is 6, so f=6 4 multiplied by 2 is 8 added by 4 is 12. The equation in numbers would be 6(2)=12 or 6(2)=4(2)+4 which ends up being 12=12.

Find the exponential function that satisfies the given conditions: Initial value = 37, increasing at a rate of 5% per year

beks73 [17]

The required function is:

Option 3: $f(t) = 37. (1.05)^t$

Step-by-step explanation:

The initial value and rate is used to write exponential function

Here

Given

Initial value = 37

Rate = r = 5%

When the rate is 5%, the next year the quantity will be 1+0.05 = 1.05 time of the current quantity.

So,

The function can be written as:

$f(t) = 37. (1.05)^t$

For initial value, put t=0

$f(t) = 37. (1.05)^0\\f(t) = 37 * 1\\f(t) = 37$

Hence,

The required function is:

Option 3: $f(t) = 37. (1.05)^t$
