Solve the system using elimination. 2x + 18y = -9 4x + 18y = -27

Elan Coil [88]

First, let's cancel out the x by multiplying 2x + 18y = -9 by -2.

-2 ( 2x + 18y = -9) = -4x -36y = 18

Then, we combine the two equations.

-4x + 4x = 0

18y - 36y = -18y

-27 + 18 = -9

Our new equation is -18y = -9.

Now, divide both sides by -18.

-18y / -18 = y

-9/ -18 = 1/2

y = 1/2

We can plug in a value for y since y = 1/2 now.

Let's use 2x + 18y = -9

Plug in y.

2x + 18(1/2) = -9

2x + 9 = -9

Then, subtract 9 from both sides.

2x = -18

Divide by 2.

2x/2 = x

-18/2 = -9

x = -9

Lastly, we can plug in both x and y values to see it works.

2(-9) + 18(1/2) = -9

-18 + 9 = -9

Therefore, the values of x and y does work.

x = -9

y = 1/2

A line includes the points (9, -7) and (-6, -2). What is its equation in slope-intercept form?

Rus_ich [418]

Answer:

$y=\frac{-1}{3}x-4$

Step-by-step explanation:

Slope-Intercept Form: y = mx + b

m - slope

b - y-intercept

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Step 1: Define

Point (9, -7)

Point (-6, -2)

Step 2: Find slope m

$m=\frac{-2-(-7)}{-6-9}$

$m=\frac{-2+7}{-15}$

$m=\frac{5}{-15}$

$m=\frac{-1}{3}$

$y=\frac{-1}{3}x+b$

Step 3: Find y-intercept b

$-7=\frac{-1}{3}(9)+b$

$-7=-3+b$

$-4=b$

Step 4: Write linear equation in slope-intercept form

$y=\frac{-1}{3}x-4$

A toy store owner estimates that by charging x dollars each for a certain toy, he can sell 40−x toys each week. The quadratic eq

djyliett [7]

Answer:x=20

Step-by-step explanation:

Given

selling Price of Toy is x dollars

he can sell 40-x toys each week

Thus Revenue Generated from selling 40-x toys at x dollar can be given by

$R=-x^2+40x$

To get maximum Revenue differentiate R with respect to x and equate it to 0

therefore $\frac{\mathrm{d} R}{\mathrm{d} x}=-2x+40$

$-2x+40=0$

$x=20$

thus for maximum Revenue owner sells 20 toys each week

Max Revenue $R=-(20)^2+40\times 20=-400+800=$ 400$
