Answer:

5x-1

Step-by-step explanation:

f(x) = 3x-2

Answer:

System 1

Step-by-step explanation:

Tbe elemination method of solving system of equation works on such a way that :

Given two set of equation (1) and (11) having two unknowns, the Coefficient are of one of the unknowns, either x or y is the same such that applying the addition or subtraction operation of the two equations eliminates one of the unknown variables leaving us with only one unknown variable to solve, and then using this solution to solve for the other variable.

In the question given. The variable setup for elimination is the x variable such that by using the addition operation, variable x is eliminated.

Answer:

A=4cm

ok to do this we do the formula

A=PiR^2

A=3.14*4^2

A=3.14*16

A=50.24

and the area of circle B is 4 times the area of a so

50.24*4=200.96

200.96=3.14*X^2

Since  r  is on the right side of the equation, switch the sides so it is on the left side of the equation. 3.14 ⋅ r 2 = 200.96  Divide each term by  3.14  and simplify.

r 2 = 64

r=8

CIRLCE A=50.24

CIRLCE B=8

Answer:

The number 1 and 47

or 13 and 59

Answer:

16 and 62

Step-by-step explanation:

Two variables x and y. x < y.

y - x = 46

y = 46 + x

4x = y + 2

y = 46 + x in 4x = y + 2

4x + y = x + y + 46 + 2

4x + y - y = x + y - y + 46 + 2

4x = x + 48

4x - x = x - x + 48

3x = 48

3x ÷ 3 = 48 ÷ 3

x = 16

y = x + 46

y = 16 + 46

y = 62

Answer:

0.563

Step-by-step explanation:

Probability is defined by the amount of desirable outcomes over the total number of outcomes. When rolling a 16 sided number cube, there are 16 different numbers you can roll, which means 16 total outcomes. There are 8 odd numbers that you can possibly roll:

1, 3, 5, 7, 9, 11, 13, 15

Now, an even prime numbers are included in the desirable outcomes too. The only even prime number is 2. Since the odd numbers and even prime numbers do not have common term, to get the total desirable outcomes, you can add the two: 8 + 1 = 9. From the basic probability formula you can say the probability is 9/16 or 0.5625. This rounds to 0.563.

If you were too lazy to calculate, you can realize that 0.563 is the only reasonable answer because it is close to 1/2 or 0.5 and half the numbers are odd and only one is even and prime which makes the amount a bit over 1/2.

Answer:

[tex]\frac{6x^3+40xy^2-45x^2y+30y^3}{60}[/tex]

Step-by-step explanation:

Primero que todo reescribiremos el problema como una ecuacion:

[tex]\frac{6}{5}x^{3}-x^{3}+\frac{4}{3}xy^{2}-\frac{3}{2}x^{2} y+y^{3}[/tex]

Ahora rompemos el parentesis cambiando el signo:

[tex]\frac{3}{5}x^{3}-\frac{1}{2}x^{3}+\frac{2}{3}xy^{2}-\frac{3}{4}x^{2} y+\frac{1}{2}y^{3}[/tex]

Ahora simplificamos los terminos con variables iguales:

[tex]\frac{1}{10}x^{3}+\frac{2}{3}xy^{2}-\frac{3}{4}x^{2} y+\frac{1}{2}y^{3}[/tex]

Ahora restamos los primeros dos terminos y los ultimos dos terminos:

[tex]\frac{3x^{3}+20xy^{2}}{30}-\frac{6x^2y+4y^3}{8}[/tex]

Y realizamos la ultima suma de fracciones:

[tex]\frac{24x^3+160xy^2-180x^2y+120y^3}{240}[/tex]

Y por ultimo podemos simplificar la espresion dividiento doto por 4:

[tex]\frac{6x^3+40xy^2-45x^2y+30y^3}{60}[/tex]

Answer:

Answer:

The number is 11

Step-by-step explanation:

From 32 you have to minus 10 because 10 is added for the number which we can say for example is X . from 32 when you minus 10 it is 22 . To find X it says that when 10 is added to twice the number , twice the number is 22 . 22 is twice the amount of X , so to find X we have to half 22 which is 11

Answer: $1,000

Step-by-step explanation:

We are trying to find 5% of 20,000. Always remember that the "of" can be changed to a multiplication, and that "percent" means per hundred.  So you will write (5/100) x 20,000 = 0.05 x 20,000 = $1,000.00
