Answer: Choice C
The pink equation is y = 2x-3
The yellow equation is y = -2x+1
Notice how the pink equation crosses the y axis at (0,-3) or at -3 on the y number line. This tells us that the pink equation has a y intercept of -3. So b = -3
This only happens with the equation y = 2x-3. The other equations do not have a y intercept of -3. So this quickly rules out the other choices leaving C as the only answer.
An alternative is to find two points on the pink line, such as (0,-3) and (1,-1). Then find the slope of the line through those points. You should find the slope to be m = 2. So m = 2 and b = -3 leads to y = 2x-3. Follow similar steps for the yellow line as well.
For this case, we must find the equation of the line.
The generic equation of the line is:

The slope of the line is:

Substituting values we have:

Rewriting:

We now choose an ordered pair:
(xo, yo) = (0, 12)
Substituting values we have:

Rewriting the equation:

For 20 visits, we evaluate the equation when x = 20.
We have then:
Answer:
The discounted entrance fee is 1.5$. The total cost is 42$ after 20 visits
adding the 2 equations eliminates x and gives:-
5y = 60
y = 12
Plug y = 12 into the first equation:-
2x + 3(12) = 40
2x = 40 - 36 = 4 so x = 2
Answer is x = 2 and y = 12.
Answer:
4m/s
Step-by-step explanation:
Velocity = ds/dt
= (change in displacement) ÷ (change in time)
= slope of the function
= 4
