Ok the answer is the 3rd one since when you see in the graph Y is going up by 2
2:1 means its by a factor of 1/2. Meaning you just use the original number and divide by 2. The answer is B

Is this Pizza hut or Papa Johns
Step-by-step explanation:
Answer:
x = 16°
4x-7 = 57°
3x+4 = 52°
5x-9 = 71°
Step-by-step explanation:
All angles of any triangle add up to 180°, so if we add up each equation and set it equal to 180 we can find x.
4x-7 + 3x+4 + 5x-9 = 180
Simplify by combining like terms.
12x-12 = 180
Then, do inverse operations to find x.
12x=192
x=16
Now that we found x, we can substitute 16 for x in each angle equation in the triangle.
4(16)-7 = 57
3(16)+4 = 52
5(16)-9 = 71
