Answer:
Step-by-step explanation:
The series is an arithmetic series with first term (a1) -9 and common difference (d) 5. Then the general term (an) is ...
an = a1 +d(n-1) = -9 +5(n-1) = -14 +5n
The summation notation indicates the sum of "n" of these terms.
If x+y=5, let y = 0 to find the x-intercept: x=5. The x-int. is at (5,0).
Let x = 0 to find the y-int: y=5. The y-int is (0,5).
Plot (5,0) and (0,5), and then draw a straight line thru both points.
If x+y=5, solving for y results in y = -1x + 5
Comparing this to y = mx + b, m=-1 and b= 5. Again, the y-int. is (0,5).
Answer:
61
Step-by-step explanation:
all angles of a triangle adds up to 180
180-77-42=61
Answer:
4. option A ---> m = 65h
Step-by-step explanation:
According to the question it states that,
- m --> number of miles traveled.
- h --> <u>over</u> hours
Now if we look at the table we need to find the starting point, or in other words, how much distance traveled in 0 hours. So we would divide miles / hours.
*Four hours, the variable in the question and in the table says n, but the answer choices says h, so I am saying h for hours just if you were wondering on it.*
distance (m) / hours (h)
130 / 2 = 65
195 / 3 = 65
325 / 5 = 65
455 / 7 = 65
So, our starting point, or numbers of miles traveled in 0 hours was 65. Now let us form an equation.
m = 65h
I would appreciate if you give me the brainlist or not. Hope this helps and stay safe, happy, an healthy, thank you :) !!
