Answer
X=96
Explanation
You have to add up the two interior angles, the angles inside the triangle, to equal the exterior angle.
- x-47+x=x+49 Combine like terms that would be the x's which would equal 2x
- 2x-47=x+49 Add 47 to both sides 49+47=96
- 2x=x+96 Subtract x on both sides 2x-x-x
- x=96
If you want to check the answer put 96 back in the x's spots. The interior angles would equal 145 and the exterior angles would equal 145 as well.
Answer:
x=14
y=30
Step-by-step explanation:
5x+25=3x+53
5x=3x+28
2x=28
x=14
2y+35=95
2y=60
y=30
(I assumed all of the angles are equal, correct me if I'm wrong.)
Answer:
Justification of step A: common denominator
Justification of step B: multliplication property of equality
Step-by-step explanation:
i got it right.
This is a composite. Another way to write them is f(g(x)). Take the function g(x) and stick it in for x in f(x). Like this:
. But we aren't done cuz there's some simplifying there to do.
and canceling out the 3's we get just a simple x as our answer. The choice is the last one above as your answer.
To find the y-intercept of the line represented by 6x - 7y = 12, we first need to rewrite the equation into standard form. Here is how you do it:
6x - 7y = 12
-7y = -6x + 12
y = 6/7x - 12/7
The y-intercept of the line represented by the equation 6x - 7y = 12 is (0, -12/7). Hope this helps and have a fabulous day!
