If you graph out y = x^2 - 1, you'll see that it is a curved parabola. It is not a straight line. So visually this shows the equation is not linear. It's considered nonlinear.

Algebraically, the given equation does not fit the form y = mx+b which is slope intercept form. So this is more confirmation that we do not have a linear function.

Nataly_w [17]

Answer:

first of all, the graphs are so poorly plotted,even kn computer...

anyways,

since the blue one ending at x=5 on the x axis,

while actual log ends at x=0 this means

X=x-5

and since, log1=0 but it's 5 in blue graph,

the graph is moved up by 5

hence,

y=5+log(x-5)

On average, a pair of bike tires can last 18 months if used every day. The length of time bike tires can last is exponentially d
aleksandr82 [10.1K]

Answer:

We conclude that eighty percent of bike tires last at most 14.4 months.

Step-by-step explanation:

We know that a pair of bike tires can last 18 months if used every day.

We calculate how much eighty percent of the tire will last in months.

We have the following proportion:

18:100\%=x:80\%\\\\100x=18\cdot 80\\\\100x=1440\\\\x=\frac{1440}{100}\\\\x=14.4

We conclude that eighty percent of bike tires last at most 14.4 months.

I would appreciate if someone could explain this to me , thanks
gizmo_the_mogwai [7]

Answer: 0.001389

Step-by-step explanation:

Since you have 6 probabilities that it could be red, you get 1/6. Now, you took 1 probability out of 6, so now you only have 5. So you multiply 1/6 by 1/5. Now you have only 4 cards. Multiply 1/ 6 * 1/5 * 1/4 and keep going (e.g 1/6 * 1/5 * 1/4 * 1/3 * 1/2 * 1). This comes out to 0.00138888888, or rounded to six decimal places, 0.001389.

If my answer was helpful, please mark it as brainliest. The other dude's answer was WRONG.
