Answer:

-5y + 8x

Step-by-step explanation:

$(-4y-x)-(y-9x)\\\\-4y-x-(y-9x)\\\\\rightarrow-(y-9x)*-1=-y+9x\\\\-4y-x-y+9x\\\\-4y-y+9x-x\\\\\boxed{-5y+8x}$

The function f(x) = 2 • 5x can be used to represent the curve through the points (1, 10), (2, 50), and (3, 250). What is the mul

Oksana_A [137]

For this case we have a function of the form:
$f (x) = 2 * 5 ^ x
$
We will evaluate the function for different values of x:

For x = 1:
$f (1) = 2 * 5 ^ 1 = 2 * 5 = 10
$

For x = 2:
$f (2) = 2 * 5 ^ 2 = 2 * 25 = 50
$

For x = 3:
$f (3) = 2 * 5 ^ 3 = 2 * 125 = 250
$

We note that for each value of x, the function is 5 times greater than the previous value.

Answer:
The multiplicative rate of change of the function is:
5
The function is 5 times greater for each value of x.

∀ set A:(A⊆A) Select one: True False

SashulF [63]

Answer:

True

Step-by-step explanation:

You're claiming that every set is a subset of itself.

That's trivially true, because

$A\subseteq A$

requires that every element of A is also an element of A, which is tautologically true.

Suppose you want to accumulate $25,000 as down payment on a house and the best you can do is to put aside $200 a month. If you d

Sunny_sXe [5.5K]

Answer:

It will take 88.2 months to accumulate the amount

Step-by-step explanation:

Given;

Future value of money, FV = $25,000

investment per compound period, P = $200

interest rate, i = 0.75% x 12 = 9%

The number of monthly installments required to amount to FV is given by;

$n = \frac{ln(FVi +cp)-ln(cp)}{ln(c+i)-ln(c)}\\\\ n = \frac{ln(25000*0.09 +200*12)-ln(200*12)}{ln(12+0.09)-ln(12)}\\\\n = \frac{8.4446 -7.7832}{2.4924-2.4849}\\\\n = 88.2 \ months$

Therefore, it will take 88.2 months to accumulate the amount.
