Finding what a number is diviseble by or finding multiples of a number
Answer:
y = 3x - 9
Step-by-step explanation:
We first need to find the slope (m)
m =
=
=
= 3
y = mx + b
y = 3x + b
(4, 3)
y = 3x + b
3 = 3(4) + b
3 = 12 + b
-12 -12
-9 = b
(1, –6)
y = 3x + b
-6 = 3(1) + b
-6 = 3 + b
-3 -3
-9 = b
y = 3x - 9
To check: (1, –6)
y = 3x - 9
-6 = 3(1) - 9
-6 = 3 - 9
-6 = -6
Hope this helps!
In simplified form it is 5x+5
Answer:
- After 17 years and 3 months
Step-by-step explanation:
<u>Given function:</u>
We are looking for the value of x at f(x) < 2000
<u>Solve the equation:</u>
- 2000 = 18000(0.88)^x
- (0.88)^x = 2000/18000
- (0.88)^x = 0.1111
- log (0.88)^x = log 0.1111
- x = log 0.1111 / log 0.88
- x = 17.18
After 17 years and 3 months the car value drops below $2,000
Answer:
Step-by-step explanation:
<u>Use trigonometry:</u>
- tangent = opposite / adjacent
- tan x = 34/54
- x = arctan (34/54) ≈ 32.2°
