Answer:
2. A = 30°
3. x = 12
Step-by-step explanation:
2.
The angle OPPOSITE of the angle "8x +4" is also same because they are vertical angles (makes a "cross").
The angle beside (adjacent) to the 130 degree angle is 50. Because a straight line is 180 degrees. So 130 ADDED to WHAT will make 180?
130 + WHAT = 180
WHAT = 180 - 13- = 50
Now, we have all the 3 angles of a triangle. We know sum of 3 angles in a triangle is 180, thus we can write:
3x - 6 + 50 + 8x + 4 = 180
Now, we can first, solve for x:
The value of "x" is 12. But we need measure of Angle A which is "3x - 6". So we plug in x = 12 in it.
A = 3x - 6
A = 3(12) - 6
A = 36 - 6
A = 30°
3.
The Square inside the triangle means the angle is a 90 degree angle. The other 2 angles are shown as algebraic expression.
We know sum of 3 angles in a triangle is 180 degrees. Thus we can write an equation in "x" and solve for x. Shown below:
Thus, the value of x is 12

If there are 5 fewer weeds, there will be 5 more roses
Step-by-step explanation:
The question states that the roses increase when the weeds decrease.
Answer:
Inverse of given function = log(x)/log(3)
Step-by-step explanation:
<u>How to find the inverse of any function?</u>
- <em>In the complete function, replace y with "x" and x with "y"</em>
- <em>Then, solve the obtained equation from step 2 for y</em>
- <em>And, then the value obtained for "y" is the inverse required i.e. = f^{-1}(x) </em>
Now, we solve the problem:
Given :- y = 3^x
replacing the value of "y" with "x", we get,
x = 3^y
to solve for "y" we should take the "logarithm" for both sides
log (x) = y log(3)
or y = log(x)/log(3)
or f^(-1) (x) = log(x)/log(3)
