Answer:
240
Step-by-step explanation:
Answer:
1st: 22, 2nd: 27, 3rd: 88
Step-by-step explanation:
Make an equation
If she recieved x calls the 1st evening, then the 2nd evening she recieved x+5, and the 3rd evening she recieved 4x.
x+x+5+4x=137
Combine like terms
6x+5=137
Subtract 5 from both sides
6x=132
Divide by 6 on both sides
x=22
First:
22 calls
Second:
x+5
22+5
27 calls
Third:
4x
4*22
88 calls
Hope this helps!
Answer:
1) The correct option is C. (2) The correct option is D. (3) The correct option is B. (4) The correct option is D. (5) The correct option is D.
Step-by-step explanation:
The slope formula is

(1)
Two points are (-2,5) and (1,4).
![m=\frac{4-5}{1-(-2)}=\frac{-1}{3}tex]Therefore option C is correct.(2)Use the above mentioned formula for each pair of coordinates.[tex]m=\frac{10-13}{17-12}=\frac{-3}{5}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B4-5%7D%7B1-%28-2%29%7D%3D%5Cfrac%7B-1%7D%7B3%7Dtex%5D%3C%2Fp%3E%3Cp%3ETherefore%20option%20C%20is%20correct.%3C%2Fp%3E%3Cp%3E%282%29%3C%2Fp%3E%3Cp%3EUse%20the%20above%20mentioned%20formula%20for%20each%20pair%20of%20coordinates.%3C%2Fp%3E%3Cp%3E%5Btex%5Dm%3D%5Cfrac%7B10-13%7D%7B17-12%7D%3D%5Cfrac%7B-3%7D%7B5%7D)



Therefore option D is correct.
(3)
The pair of points (6, y) and (10, -1). The slope is
.




Therefore option B is correct.
(4)
For vertical line the x coordinates always remains the same. Therefore when we subtract the same number we get zero in the denominator, therefore the value of slope is undefined for a vertical line.
Therefore option D is correct.
(5)
Two points from the table are (2,110) and (3,165).

Therefore option D is correct.
Answer:
The coefficient of the term 13a is, 13
Step-by-step explanation:
Coefficient term are the numbers that multiply the variables or letters
In the given expression: 
13a means 13 times a , and a is the variable,
so 13 is the coefficient .
6b means 6 times b , and b is the variable ,
so 6 is the coefficient .
therefore, the coefficient of the term 13a in the given expression is, 13.
