25 x² - 10 x = 0
5 x ( 5 x - 2 ) = 0
x = 0  and
5 x - 2 = 0
5 x = 2
x = 2: 5 
x = 2/5
Answer: B ) x = 0 and x = 2/5

Answer:

B. x = 0 and x = 2/5

Step-by-step explanation:

To get the value satisfying the equation, we will need to simplify the given equation 25x²-10x = 0 to have:

First we will factor out '5x' which a common factor to have;

5x(5x - 2) = 0

5x = 0 and 5x-2 = 0

From 5x = 0, x =0

From equation 5x-2=0, 5x= 0+2

5x = 2

Dividing both sides by 5 which is the coefficient of x we have;

5x/5 = 2/5

x = 2/5

The solutions will give;

x = 0 and x = 2/5

If you earn $1200 per month and you expect your earnings to increase by 10% per year, what monthly salary would you be making in
Sergio [31]
So u turn the percent into a decimal.
0.10 
Now multiply 1200 * 0.10
1200*0.10= 120 ( 120 is the amount that is gonna increase)
So if it says 5 years, than your gonna multiply 120 * 5 
120*5 =600
So your gonna add 600 to 1200.
So in five years your gonna be making 1,800.
An easier way would be to use prt
Principle * rate * time
1200 * 0.10* 5
= 600
So now you just add 600 to 1200
= 1800

3. Suppose you were collecting data about dogs. Give at least two examples of discrete and two examples of continuous data you m
Mashutka [201]

Answer:

The discrete data can be number of legs, number of teeth.

The continuous data can be the length of tail, and the height of dog.

Step-by-step explanation:

Consider the provided information.

The discrete data is a data whose value is obtained by counting and they can be described by an integer value.

So, the discrete data can be number of legs, number of teeth.

A continuous data is a variable whose value is obtained by measuring.

The continuous data can be the length of tail, and the height of dog.

A local candy shop sells boxes of chocolate for $3.75 each. If a customer purchases six or more boxes, the cost is only $3.25 pe
blagie [28]

The piecewise function that models the scenario is:

c(x) = $3.75*x + $5   if x < 6

c(x) = $3.25*x + $5  if x ≥ 6.

<h3>How to write a piecewise function?</h3>

A piecewise function is a function that behaves differently in different intervals of the domain, like this one, where the cost per box changes depending on the number of box.

The function in this case, if we define x as the number of boxes bought, is:

  • c(x) = $3.75*x + $5   if x < 6
  • c(x) = $3.25*x + $5  if x ≥ 6.

Where the cost per box changes for x equal or larger than 6.
