Solve the equation for x by graphing.

Mathematics
1 answer:
olchik [2.2K]3 years ago
6 0
Answer:
x ≈ -0.24

Explanation:
Using a graphing tool to graph the given equation, we will end up with the graph shown in the attached image.

Now, to solve the equation means to find the x-intercept.

Taking a look at the graph, we would find that the x-intercept is somewhere between the -0.2 and the -0.3

This means that the best choice is x ≈ -0.24

We can check using algebraic substitution:
-3x + 2 = -3(-0.24) + 2 = 2.72
4ˣ +2 = 4⁻⁰.²⁴ + 2 = 2.7169
We can note that the two values are almost equal.

Hope this helps :)

Answer:

  y = 15·2.1599^x

Step-by-step explanation:

We know that the number changed by the ratio 1523/15 = 101.5333... in 6 days, so the daily multiplier is the 6th root of this:

  b = 101.5333...^(1/6) = 2.1599 . . . rounded to 4 dp

Of course, the coefficient 'a' in the equation is the initial number, 15.

Your exponential equation is ...

  y = 15·2.1599^x

  a = 15

  b = 2.1599

jason cycled for 3 hours. He cycled 7 1/2 miles each hour for the first 2 hours and the distance he cycled for the 3rd hour was
11111nata11111 [884]
7 1/2 * 2 = 15

The 3rd hour was 1/4 of the total distance in 3 hours. 

1/4 = 0.25 as a decimal, and 25% as a percent. 

15 (0.25) = 3.75
15 + 3.75 = 18.75

0.75 = 3/4 as a fraction.

So, he cycled 18 3/4 miles in 3 hours. 

I hope this helps, and I am sorry if I get this question wrong. (which is in all likelihood)
