Answer:
10.8 meters
Step-by-step explanation:
1.2 times 9 minutes= 10.8
F(x) = 2/3x - 1......f(x) represents y
to find ur points, sub in any number for x and solve for f(x) or y
lets let x = 0
y = 2/3(0) - 1
y = -1
so when x = 0, y = -1......so (0,-1) is one point
let x = 3
y = 2/3x - 1
y = 2/3(3) - 1
y = 6/3 - 1
y = 2 - 1
y = 1.....so when x = 3, y = 1....(3,1) <== another point
let x = 6
y = 2/3(6) - 1
y = 12/3 - 1
y = 4 - 1
y = 3....so when x = 6, y = 3.....(6,3) <== another point
let x = 9
y = 2/3(9) - 1
y = 18/3 - 1
y = 6 - 1
y = 5.....so when x = 9, y = 5....(9,5) <== another point
let x = 12
y = 2/3(12) - 1
y = 24/3 - 1
y = 8 - 1
y = 7...so when x = 12, y = 7....(12,7) <== ur fifth point
=========================
f(x) = 2/3x - 1
y = 2/3x - 1....in y = mx + b form, ur b represents the y int. So ur y intercept(where the line cross the y axis) is (0,-1)
to find the x intercept, sub in 0 for y and solve for x
y = 2/3x - 1
0 = 2/3x - 1
-2/3x = -1
x = -1 * -3/2
x = 3/2.....so ur x int (where ur line crosses the x axis) is (3/2,0)
now just plot all the points we just found, connect them, and they should make a straight line
Answer:
I think B 82.3%
Step-by-step explanation:
Initial investment = $775
Monthly investments = $C
Period of investment = 1 year = 12 months
Total monthly investments = Monthly amount*12 = C*12 = 12C
Total investment after 12 months = Initial investment + Total monthly investments = 775 + 12C
The growth of the population can be expected to be about 3000 a year, so for the youer 2020 the figure 53 000 is the closest 33000 + 7 x 3000 = 54 000SHOW FULL ANSWER
