When a question is asking you for the y-intercept based on a graph, all you have to do is look to see at what point does the function cross/intersect the y-axis. The x-value will always be zero in a y-intercept. By looking at the graph you see that the function crosses the y-axis at the point (0, -1), which is your answer.
Answer: (0, -1)
It's looking for the measures
m<F + m<G = 180°
(4x)° + (8x)° = 180°
12x = 180°
÷12 ÷12
x = 15
check your work
m<F + m<G = 180°
(4x)° + (8x)° = 180°
4(15)° + 8(15)° = 180°
60° + 120° = 180°
Answer: A
Step-by-step explanation:

Answer: 5.8b
Step-by-step explanation:
Selling Price = $145
Charge on first $25 is 5.25%
5.25% of $25 =

Charge on rest is 3.25%
rest amount = $145 - $25 = $120
3.25% of $120 =
