Answer:
<u>Create a function representing number of published articles per month:</u>

Where:
- a = total number of articles published
- m = number of months
- 12 = slope = number of articles published per month
- 60 = y-intercept = number of published articles at the start (month 0)
<u>Now substitute in the values of m to get the a-value:</u>
- m = 1 → a = 12(1) + 60 = 72
- m = 3 → a = 12(3) + 60 = 36 + 60 = 96
- m = 4 → a = 12(4) + 60 = 48 + 60 = 108
- m = 9 → a = 12(9) + 60 = 108 + 60 = 168
Answer:
6F
Step-by-step explanation:
Let x be the temperature at noon
dropping means we subtract
The temperature at 9 pm was -4. That goes on the right hand side of the equals
x-10 = -4
Add 10 to each side
x-10+10 = -4+10
x = 6
The temperature at noon was 6 F
Answer:
(5,-3)
Step-by-step explanation:
9x+2y=39
6x+13y=-9
---------------
117x+26y=507
12x+26y=-18
----------------------
105x=525
x=5
Substitution
9(5)+2y=39
45+2y=39
2y=-6
y=-3
Answer:
Step-by-step explanation:
to find x we can use tangent function
tan 31= x/9
0.60=x/9
x=0.60*9=5.4 choice B
