Answer:

En matemáticas, un número primo es un número natural mayor que 1 que tiene únicamente dos divisores distintos: él mismo y el 1. Por el contrario, los números compuestos son los números naturales que tienen algún divisor natural aparte de sí mismos y del 1, y, por lo tanto, pueden

factorizarse .

Answer:

Step-by-step explanation:

Prime numbers definition: A prime number is a natural number greater than 1 that cannot be formed by multiplying two smaller natural numbers. A natural number greater than 1 that is not prime is called a composite number. For example, 5 is prime because the only ways of writing it as a product, 1 × 5 or 5 × 1, involve 5 itself.

Odd numbers vs even numbers:

An integer is even if it is divisible by two and odd if it is not even. For example, 6 is even because there is no remainder when dividing it by 2. But, 3, 5, 7, 21 leave a remainder of 1 when divided by 2.

Solve the system by graphing. Write the solution as an ordered pair. y = 1/3x + 2 y = –x – 2

Dima020 [189]

ANSWER

The solution is where the two graphs intersect, which is
$(-3,1).$

EXPLANATION

The given system of equations are
$y = \frac{1}{3} x + 2$
and

$y = - x - 2$

We need to graph the two equations.

Let us graph

$y = \frac{1}{3} x + 2$
first.

We need at least two points.

You can choose any appropriate value for x and solve for y. Choosing zero makes our working easier. So let us plot the intercepts.

When
$x = 0$

$\Rightarrow \: y = \frac{1}{3} (0) + 2$

$\Rightarrow y = 0 + 2$

$\Rightarrow y = 2$

So this gives us the ordered pair,

$(0,2)$

When
$y = 0$
we get,

$0= \frac{1}{3} x + 2$

$\Rightarrow \: - 2 = \frac{1}{3} x$

$\Rightarrow \: - 2 \times 3= x$

$\Rightarrow \: -6= x$
This also gives the ordered pair

$(-6,0).$

We plot these two points and draw a straight line through them to obtain the blue graph in the attachment.

For the second line

$y = - x - 2$

We again find the intercepts and plot them.

When
$x = 0$

$y = - 0 - 2$

$\Rightarrow \: y = - 2$

This gives the ordered pair

$(0,-2)$

Also, when
$y = 0$

then we have,

$0 = - x - 2$

$2 = - x$

$x = - 2$

Then we again have the ordered pair,

$(-2,0)$

We plot these two points on the same graph sheet to obtain the red graph above.

The intersection of the two lines is
$(-3,1)$

You will get good grades so don't worry much.

X^2+10x-6=0.........

Georgia [21]

Puting it into the quadrait equation ((-b+-[b^2-4ac]^(1/2)/2a), we get that x= 31^(1/2)-5 or 31^(1/2)+5

A tree that is 3 feet tall is growing at a rate of 32% each year. How tall will it be in 3 years?

pashok25 [27]

Answer: 5.88 feet tall

Step-by-step explanation:

Using this formula

Interest =principal×rate×time/100

Principal is the actual growth=3ft

Rate is the 32%

Time is 3yrs

Interest =3×32×3/100

Interest =2.88

To get the value for 3yrs,add the interest to the principal value

Exact value in 3yrs=

3+2.88

=5.88 feet tall

babunello [35]

Answer:

50065

Step-by-step explanation:

5x500 is 2500, 5x80 is 400, 5x9 is 45. 80x500 is 40000, 80x80 is 640, 80x9 is 720. I split them all up and when you add them it makes 50065
