I hope I am reading the problem right: The price of a mountain bike increased by 20% in the past year. The value is $150. What was the value of the mountain bike last year?
Let's simplify this. One year, there was this radical mountain bike that used to have an unsaid price, <em>x. </em>That year, that price of x increased by 20% more than it was before, or <em>120% times the original value</em>. Because of that, it's now $150.
We can equation this.
1.20x = 150
x = 150/1.2
x = 125
The bike, I believe, cost $125 last year. Hope this helps!
Answer: −10
Step-by-step explanation: 9^2−21/−6
81−21/−6
60/−6
−10
The function is the Sine Curve
y = sine (x)
Answer:
Slope is 40
Full equation: y=40x-586
Step-by-step explanation:
Slope is y2-y1/x2-x1
14 is x1
-26 is y1
15 is x2
14 is y2
14-(-26)/15-14
40
So the slope is 40
To find the equation
y=40x+b
14=15(40)+b
14=600+b
b=-586
Equation:
y=40x-586
