Answer:

<h2><u><em>The function basically returns the same objects (= does nothing). This could also be written explicitly as a named function. new Function <- function(x) { x } which would then be. cross val <- function(data, lambda=0, y trans = new Function) This is the default value, like in lambda=0, except the default value is a function itself.</em></u></h2><h2><u>brainlist plz </u></h2>

Area of sector = PI x r^2 x (angle/360)

area = PI x 10^2 * (45/360)

area = PI x 100 * 45/360

Area = 25/2x PI

Area = 25PI/2

My first expression answer is y=5 -2x How do I plug it into x-y=1 ?? The Y
Lemur [1.5K]

Answer:

All you need to do is make sure the first expression is solved for y (which it is), and then substitute it into the second expression in place of any occurrences of y:

given the second expression:

x - y = 1

We'll replace y with it's value in the first expression:

x - (y) = 1

x - (5 - 2x) = 1

Now we can expand the resulting equation:

x - 5 + 2x = 1

So <em>neither</em> of the answers provided are correct.

You can then solve for x:

x - 5 + 2x = 1

x - 5 + 5 + 2x = 1 + 5

x + 2x = 6

3x = 6

3x/3 = 6/3

x = 2

After that, you can find y by plugging x into either of the two original equations:

y = 5 - 2x

y = 5 - 2(2)

y = 5 - 4

y = 1

Peter deposited $8,975 into a savings account 21 years ago. The account has an interest rate of 3.8% and the balance is currentl
Alexus [3.1K]
The formula for the future value of the account is
  A = P(1 + r/n)^(nt)
where you have
  A = 19909.20
  P = 8975
  r = 0.038
  t = 21

The resulting equation is not one that can be solved by algebraic means, but we can use a graphing calculator to find n. This graph shows us n = 12, so

the interest compounds monthly.

Y= -3+ 2x<br><br> 3x+2y=2<br><br> I need help ASAP <br> What the solution for this someone pls
Delvig [45]
Substitute the 1st equation in the 2nd, we get:

3x + 2(-3 + 2x) = 2
3x -6 +4x = 2

7x = 8
x = 8/7

Replace x = 8/7 in equation 1,

y = -3 + 2(8/7) = -3 +16/7 = -5/7
