Answer:
Company A: 
Company B: 
Step-by-step explanation:
The initial fee is the y-intercept, as that is the cost at x = 0, or the cost before any time has passed. Afterwards, the rate the cost increases is the slope.
Linear equation in slope-intercept form:
where m is the slope and b is the y-intercept.
Company A charges $50 up front and $40 per hour afterwards, so the equation would be:
Company B charges $25 up front and $50 per hour, so:
Answer: is there a question for/to the numbers gjven
Answer:
Height of the building = 50.8 ft
Step-by-step explanation:
A person and a building are casting the shadows at the same time of the day.
Triangles formed by the person and his shadow and the building and its shadow will be similar.
Therefore, corresponding sides of the similar triangles will be proportional.
x = 
x = 50.75
x ≈ 50.8 ft
Answer:
1/2
Step-by-step explanation:
Let's pick two points and find the slope inbetween them.
I'll pick (2,1) and (0,0).
Remember that slope = change in y / change in x.
slope = 1-0 / 2-0 = 1/2
Answer:
E
Step-by-step explanation:
You can easily solve this by rearranging the ones that look alike. 7a^2-5a^2+10a-3a=5a^2+7a
