If f(x) = 5x – 2 and g(x) = 2x + 1, find (f+9)(x). A)3x-1 B)7x-1 C)7x-3 D)4x-3
1 answer:
<h3>Answer:</h3>
B) 7x - 1
<h3>Step-by-step explanation:</h3>In this question, you're going to solve by adding both f(x) and g(x) together.
You're finding (f+g)(x), meaning that you will be adding both of the equations to get your answer.
What (f+g)(x) looks like:
(5x - 2 + 2x + 1)(x)
What you would do is solve to get your answer. You're going to be combining like-terms and adding.
When you're done solving, you should get 7x - 1
This means that B) 7x - 1 would be the correct answer.

Answer:
The answer to your question is: x = - 102
Step-by-step explanation:
-x = 17 x 6
-x = 102
x = -102
Answer:
10x+2
Step-by-step explanation:
First we work on the paranthesis. We will times 5 and 2x to get 10x
and then we times 5 and 3/4 to get 3
So now we have 10x+3-1.75
Next, we subtract 3-1.75 which is 2
Lastly we look at the equation as a whole!
10x+2
Diagram of two triangles
The two triangles are similar because they are both right triangles, meaning that one angle is 90° and the other two are acute (less than 90°).
The diagram on the left is missing its hypotenuse - the variable <em>c</em><em>.</em><em> </em>The hypotenuse is opposite of the right angle. The diagram on the right side is missing one of its legs.
Note: The hypotenuse is the <em>longest</em><em> </em>side of a right triangle.
Word Problen
The legs are 21 blocks and 20 blocks because they are by the right angle. Use the Pythagorean theorem to find the diagonal path's length, which is the hypotenuse.
Standard form of Pythagorean theorem.
Equation with the legs substituted and the missing hypotenuse value - <em> </em><em>c</em><em>.</em>
Square the legs and add.
Take the square root and simplify. The square root of 841 is 29 and -29, but distance is positive.
Thus the diagonal distance is 29 blocks.
Check by substituting.
