Hello!
If By = 52 then m<BAY = 26
m<BAC = 90
m<BAC = m<BAY + m<YAC
Substitute the values we know
90 = 26 + m<YAC
Subtract 26 from both sides
64 = m<YAC
The answer is B
Hope this helps!
Let be the number of days spent at Tahoe and San Francisco, respectively.
We don't know the values of and yet, but we know that the holiday lasted 9 days:
We also know that each day spent in Tahoe costed 350 and each day spent in San Francisco costed 475. So, the total cost of the holiday is the sum of the number of days muliplied by their cost:
If we put the two equations together, we have the system
Which yields
Answer:
A) Yes, m=-3 and b = -3
Step-by-step explanation:
The m is the slope of the line and the b is the y-intercept. We can see that the y-intercept is at -3, so that means D and B are not the answer. This leaves us with A and C. The slope of the line is going down instead of up, meaning that the slope of the line is negative. This means that C is not the answer.
Therefore, the answer is A, m= -3 and b= -3.
