When f(3)

Then we have:

3=2x

Now we divide by 2 (on both sides)

and are left with

x = 1.5

Hope this helps :)

Answer:

Step-by-step explanation:

Given that f(3), x=3.

Since f(x) = 2x, we plug in 3 for x, and get 2 times 3. Therefore, the answer comes out to 6.

Angle A and B are supplementary angles. The measure of angle B is twice the measure of angle A minus 24. Find the measure of the

ivann1987 [24]

Answer:

A = 58

B = 112

Step-by-step explanation:

A + B = 180 Supplementary angles

B = 2A - 24 Given

Substitute for B in the first equation

A + 2A - 24 = 180

3A - 24 = 180 Add 24 to both sides

3A = 180 + 24 Combine the right

3A = 204 Divide both sides by 3

A = 204/3

A = 68

B = 2A - 24

B = 2*68 - 24

B = 136 - 24

B = 112

The image below shows two parallel lines cut by a transversal. What is the value of x?

Nina [5.8K]

Since the two lines are parallel and it is cut by a transversal,
75+X+5=180
=>80+X=180
=>X=180-80
==>X=100
Hope this helps u...!!!!!

Rewrite the following expression as a single logarithm. Which letter is the correct answer?

Pepsi [2]

Answer: OPTION B

Step-by-step explanation:

You need to remember the logarithms properties:

$log(a)+log(b)=log(ab)\\\\log(a)-log(b)=log(\frac{a}{b})\\\\log(a)^b=blog(a)$

Then, you can rewrite the expression as a single logarithm:

$log(x+3)^2+log(x-7)^3-log(x-2)^5-log(x^2)\\\\log((x+3)^2(x-7)^3)-log(\frac{(x-2)}{(x^2)})\\\\log(\frac{(x+3)^2(x-7)^3}{x^2(x-2)^5})$

This matches with the option B.
