Answer:
Step-by-step explanation:
3x + x + 60 = 180.
first, we add the x's together.
4x + 60 = 180
then we see if they all have a common multiple. in this case, they do. they are all divisible by 4, so we can use that.
x + 15 = 45
then, just subtract 15 from both sides, that way we get the variable by itself.
x = 30
also, it is a right triangle. the top angle (3x) multiplied by 3 is 90. any triangle that has a 90 degree angle is automatically a right triangle.
Draw the parabola and see if the parabola matches the main curve
Answer:
m∠S = 29.5
Explanation:
Q
S 
R
In this triangle, QR = SQ, which means its an isosceles triangle, angle S and R is similar.
<u>Thus solve:</u>
m∠S = (180° - 121°)/2
m∠S = 29.5°
The function that is graphed is...
B.) y = |x - 3| - 4
Since the lines "|" in the function make it a V shape.
And when you graph the one point where the the 2 lines meet it is.
(-3, -4)
So this answer is correct. :P
Good Luck! :)
Answer:
5/12
Step-by-step explanation:
All of the other answers share at least one factor they can be divided by (the numerator in all cases). 5/12 however shares no factors and cannot be simplified anymore.
