Solve the system of equations below.
5.1 – 2y=18
3.x+3y=15

Answer:

y = 80+ 15*x

members = initial membership + growth* months

y = 80+ 15*x

Answer:

y = -6

Step-by-step explanation:

To simplify this equation as much as possible, we have to get the variable y by itself.

To do this, we would do the inverse operation of subtraction and add 7 to the left and right side of the equation.

-7 + 7 + 5y = -37 + 7

The 7s cancel out on the left side because -7+7 = 0 and so we are left with,

5y = -30

Then we would do the inverse operation of multiplication and divide by 5 on the left and right side of the equation.

5y/5 = -30/5

y = -6

So,

m<1=45, m<2=135

So the right answer is of option D.

The product of two rational numbers is always rational

Proof:

Let a = p/q and b = r/s be two rational numbers. We will have p,q,r,s be integers where denominators q and s are nonzero. We cannot divide by zero.

Multiplying a and b gives

a*b = (p/q)*(r/s) = (p*r)/(q*s)

Due to the closure property of integer multiplication, the expressions p*r and q*s are integers. The result we get is in the form of integer/integer. Basically we have two integers being divided. Furthermore, q*s is nonzero as neither q nor s is zero.

Therefore, if a and b are rational, then a*b is also rational as well.

Answer:

Joey sold 6 cars

Step-by-step explanation:

Joey earns $350 per week + $200 per car he sells

The number of cars that he sold last week is unknown, so represent it with a variable, x.

Write an equation

$350 + $200x = $1,550

Subtract $350 from both sides of this equation

$200x = $1200

Divide both sides of the equation by 200

x = 6

Answer:

280

Step-by-step explanation:

each of those squares are 100 and each bar is 10

add up the squares and you have 200

add up the bars and you have 80

add 200 and 80 and you have your answer. 280

Answer:

D

Step-by-step explanation:

Well, the bars, if you count them are ten for each column.

There are 8 bars on the right, so that is 280 - 80 = 200

There are two squares that are ten by ten, so that is 200 - 100 * 2 = 0

Step-by-step explanation:

10mm is 1cm

100mm is 10cm

200mm is 20cm

300mm is 30cm

400mm is 40cm

450mm is 45cm

So 45cm equals 450mm

Answer:

The answer is 45cm = 450mm.

Step-by-step explanation:

Given that 1cm = 10mm so for this question :

[tex]1cm = 10mm[/tex]

[tex]45cm = 10mm \times 45[/tex]

[tex]45cm = 450mm[/tex]

Answer:

$64

Step-by-step explanation:

Since the store buys the racket for $40 then marks it up, the store is selling it for 160% of the wholesale price. X is the price we are looking for - the price after it was marked up.

40 / x = 100/160

(40/x) * x = (100/160) * x      

40 = 0.625 * x  

40/0.625 = x

64 = x

x = 64

The equation of the newly translated graph is y = 5x².

A mathematical statement that has an "equal to" symbol between two expressions with equal values is called an equation. The equation in mathematics is the relationship between the variables and the number and establishes the relationship between the two or more variables.

A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.

The translated graph is represented by the equation y = 5x². The graph of the two equations is attached with the answer below.

Therefore, the equation of the newly translated graph is y = 5x².

best food to eat is a mixture of non diary and diary like avocado toast

Step-by-step explanation:

Answer:

f(x) = 2x³ - 12x² - 2x + 60

Step-by-step explanation:

Given that the zeros are x = - 2, x = 3, x = 5 , then the factors are

(x + 2), (x - 3), (x - 5)

The polynomial is then the product of the factors, that is

f(x) = a(x + 2)(x - 3)(x - 5) ← a is a multiplier

To find a substitute (6, 48) into the polynomial

48 = a(8)(3)(1) = 24a ( divide both sides by 24 )

a = 2 , thus

f(x) = 2(x + 2)(x - 3)(x - 5) ← expand the last 2 factors using FOIL

     = 2(x + 2)(x² - 8x + 15) ← distribute the parenthesis

     = 2(x³ - 8x² + 15x + 2x² - 16x + 30)

     = 2(x³ - 6x² - x + 30) ← distribute by 2

     = 2x³ - 12x² - 2x + 60

Using the factor theorem, it is found that the polynomial function is given by:

[tex]p(x) = 2(x^3 - 6x^2 - x + 30)[/tex]

-----------------------------

Factor theorem:

Given a polynomial f(x), this polynomial has roots [tex]x_{1}, x_{2}, x_{n}[/tex] such that it can be written as: [tex]a(x - x_{1})*(x - x_{2})*...*(x-x_n)[/tex], in which a is the leading coefficient.

-----------------------------

The polynomial is given by:

[tex]p(x) = a(x - x_1)(x - x_2)(x-x_3)[/tex]

[tex]p(x) = a(x - (-2))(x - 3)(x - 5)[/tex]

[tex]p(x) = a(x + 2)(x - 3)(x - 5)[/tex]

[tex]p(x) = a(x^2 - x - 6)(x - 5)[/tex]

[tex]p(x) = a(x^3 - 6x^2 - x + 30)[/tex]

-----------------------------

[tex]p(x) = a(x^3 - 6x^2 - x + 30)[/tex]

[tex]48 = a(6^3 - 6(6)^2 - (6) + 30)[/tex]

[tex]24a = 48[/tex]

[tex]a = \frac{48}{24}[/tex]

[tex]a = 2[/tex]

Thus, the polynomial is given by:

[tex]p(x) = 2(x^3 - 6x^2 - x + 30)[/tex]

Test

Answer:

0.5

Step-by-step explanation:

The probability that the first mouse turns left and the second mouse turns right is 0.5 × 0.5 = 0.25.

The probability that the first mouse turns right and the second mouse turns left is 0.5 × 0.5 = 0.25.

So the probability that only one mouse turns left is:

P =  0.25 + 0.25

P = 0.5

Another way of looking at it: the probability that only one mouse turns left is 1 minus the probability that both turn left or both turn right.

P = 1 − (P(both left) + P(both right))

P = 1 − (0.5 × 0.5 + 0.5 × 0.5)

P = 0.5

The variable is the main part, it is the base of the whole thing

The variable is the main part, it is the base of the whole thing that shows all the critical points for the inequality ? , x = 1, and x = 2 x = –6 and x = 2 x = –4 and x = 2 x = 2.

Solve a rational inequality.

Determine the critical points–the points where the rational expression will be zero or undefined. Use the critical points to divide the number line into intervals. Test a value in each interval. Above the number, the line shows the sign of each factor of the rational expression in each interval.

To find the critical points of a function y = f(x), just find x-values where the derivative f'(x) = 0 and also the x-values where f'(x) is not defined. These would give the x-values of the critical points and substituting each of them in y = f(x) will give the y-values of the critical points.
