Given that the function is given by:
f(x)=2x+x
when x=3, then:
f(3)=2(3)+3
f(3)=6+3
f(3)=9
b] The zero of the function will be given by:
f(x)=2x+x=3x
When x=0 then f(x)=0, hence the zero of the function will be at x=0
Answer:
C.
Step-by-step explanation:
Before graphing this equation we first need to isolate y on one side like so...
y + 2 = 3(x+1) ... distribute the 3 to both values inside the parenthesis
y + 2 = 3x + 3 ... subtract 2 on both sides
y = 3x + 1
Now that we have the y variable isolated we see that the slope of the function is 3, meaning that for every 1 unit right the line needs to move 3 units up. We also have the value where the line needs to cross the y-axis and that is 1. Using this information we see that the correct graph is C.
Answer:
52
Step-by-step explanation:
I'm pretty sure the answer is 52.
In Jim and Dave each got 5 and David got 4 then :
65/5 = 13
65 - 13 = 52
or
5 4 5
10 8 10
15 12 15
20 16 20
25 20 25
30 24 30
35 28 35
40 32 40
45 36 45
50 40 50
55 44 55
60 48 60
65 52 65
