5x+y=8 equation 1

x+2y=5 equation 2

Subsitute (1,3) in bothe equations if the right side is equal to.the left side of the equation then (1,3) is a solution

5(1)+3=8

1+2(3)=7

7 isn't equal to 5 so 1,3 is NOT a solution for this system of equations

Answer:

No, because substituting the given ordered pair doesn't yield two true expressions

Answer:

Hypotonic = More water outside a cell than inside

The amount of substance in a certain place = Concentration

Hypertonic = More water inside a cell than outside

Moves water into and out of cells = Osmosis

Isotonic = Equal amounts of water inside a cell as outside

Moves particles live oxygen into cells = Diffusion

step by step:

if its f(2) then u replace x with 2 so it would look like

f(2) = 3(2) - 5

3 times 2 is 6

6-5 is 1

thats how u solve it

Yes you are correct. It equals 1

Answer:

x = 20

Step-by-step explanation:

You can use Pythagorean theorem which is [tex]a^2 + b^2 = c^2[/tex]

a = 12

b = 16

and c would be x.

12^2 + 16^2 = c^2

144 + 256 = c^2

400 = c^2

square root

c = 20 or x = 20

Answer:    9.2

Step-by-step explanation:

Answer:

x = -36

Step-by-step explanation:

Distribute 1/2 to x - 12 first to get 1/2x - 6.  Combine -6 and 4 together to get -2.  Your equation should now be 1/3x - 8 = 1/2x - 2.  Subtract 1/3x on both sides to get 1/6x.  Add 2 on both sides to get -6.  Since you are dividing a fraction number, you want to do the opposite and instead multiply 6 on both sides to get your x value which is -36.

Answer:

x = -36.

Step-by-step explanation:

1/3x - 8 = 1/2(x - 12) + 4

multiplying through by the LCM 6;

6 × 1/3x - 6 × 8 = 6 × 1/2(x - 12) + 6 × 4

2x - 48 = 3(x - 12) + 24

2x - 48 = 3x - 36 + 24

2x - 48 = 3x - 12

-48 + 12 = 3x - 2x

-36 = x

hence x = -36.

Answer:d

Step-by-step explanation:

The function which represents the number of tickets remaining after x hours is b. y = -3,000x + 12,000.

A function can be defined as the values of the inputs for which the output is defined. The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.

From the given graph we can observe that every hour 3000 tickets were sold.

Assuming hours to be x and tickets remaining at any time is represented

by y and as the tickets were sold we can denote it with a negative sign.

∴ The function which represents the number of tickets remaining after x hours is,

y = -3000x + 12000.

To check whether our function is correct or not we can put any value of x from 1 to 4 in our function.

Answer:

  R = -500x^2 +9500x +126000

Step-by-step explanation:

The revenue is the product of number of members and membership fee. For a price increase of x, the number of members is said to be ...

  14,000 -500x

For a price increase of x, the membership fee will be ...

  9 +x

Then the revenue is ...

  R = (14000 -500x)(9 +x)

  R = -500x^2 +9500x +126000

Answer:

Alecia would have sold 400 boxes.

Kendra would have sold 100 boxes.

Step-by-step explanation:

First we have to find the unit rate of each girl's cookie sale.

Kendra: 50 ÷  20 = 2.5

This mean Kendra sold 2.5 cookies each day.

If Alecia sold twice as many boxes, that would be 100 boxes. And if it was in half amount of days, that would be 10 days.

Alecia sold 100 boxes in 10 days.

100 ÷ 10 = 10

She sold 10 boxes each day.

Alecia: 10 × 40 = 400

Kendra: 2.5 × 40 = 100

Answer:

in 40 days Kendra will have sold 100 boxes and her sister sold 160

Step-by-step explanation:

set up proportions for each sister

Kendra:  50/20 = b/40        cross-multiply to get 20b = 200

Alecia:  40/10 = b/40        cross-multiply to get 10b = 1600

Answer:

it's answer is 90 percent

Answer:

y=4^x −1

x intercept is the point when y = 0, so you sub in 0 for y:

0 = 4^x - 1

4^x = 1

Any number excluding 0 that is raised to the the exponent 0 always equals 1, 0^0 is undetermined.

x = 0

x intercept = (0,0)

If the x intercept is at the origin (0,0) than the y intercept is also (0,0)

s is the only line that passes through (0,0)
