Answer:
43°
Step-by-step explanation:
80°-37°= 43°
Answer:
angle 2=120°
angle 1=60
Step-by-step explanation:
70+50=120
or
180-(70+50)=60
angles on a straight line add up to 180°
180-60=120

The functions ranked from least to greatest based on their axis of symmetry: h(x), f(x), g(x).
Answer: y = 3x + 1
<u>Step-by-step explanation:</u>
The equation is in Slope-Intercept format: y = mx + b where
- m is the slope <em>(difference in y's over difference in x's)</em>
- b is the y-intercept <em>(value of y when x = 0)</em>

b = 1 <em>refer to the table that shows y = 1 when x = 0</em>
Now input m = 3 and b = 1 into the Slope-Intercept formula:
y = 3x + 1
