Eileen drove for 85 minutes. This is 21 more minutes than one third the number of minutes Ethan drove. How do I put this into an

Lapatulllka [165]

So let's start out by labeling Ethan as X

Since 85 is 1/3 of what Ethan drove, that means Ethan drove 3 times of 85.

85= (3x) -21
85 -21 = 3x
60=3x
20 = x

Virty [35]

Answer:

$\int\limits^1_0 \int^1_0{z} \, dA$

Step-by-step explanation:

$\int\limits^1_0\int^1_0 {9-4x^2-5y^2dy} \, dx$

$\int\limits^1_0 {9y-4x^2y-\frac{5y^3}{3}|_0 ^1 } \, dx$

$\int\limits^1_0 {22/3 -4x^2} \, dx$

You finish the leftover.

Given the function f(x) = x3 + x2 − 2x + 1, what is the resulting function when f(x) is shifted to the left 1 unit?

irga5000 [103]

For this case we have the following function:

$f (x) = x ^ 3 + x ^ 2 - 2x + 1$

We apply the following function transformation:

Horizontal translations:

Suppose that h> 0

To graph y = f (x + h), move the graph of h units to the left.

We have then for h = 1:

$f (x + 1) = (x + 1) ^ 3 + (x + 1) ^ 2 - 2 (x + 1) + 1$

Rewriting we have:

$f (x + 1) = (x ^ 3 + 3x ^ 2 + 3x + 1) + (x ^ 2 + 2x + 1) + (-2x - 2) + 1$

Rewriting we have:

$f (x + 1) = x ^ 3 + 4x ^ 2 + 3x + 1$

Answer:

The resulting function when f (x) is shifted to the left 1 unit is:

$f (x + 1) = x ^ 3 + 4x ^ 2 + 3x + 1$

(05.05)<br> What is the rate of change of the linear relationship modeled in the table? (4 points)

Valentin [98]

Answer:

-1

Step-by-step explanation:

all you gotta do is do rise over run which is just y over x so you get -1/+1 which equals -1

hope this helps!

have a good one!!

God bless you!
