Let S represent the cost of a small box, and L represent the cost of a large box.

Matt's sale can be represented by the equation
  3S +14L = 203
Ming's sale can be represented by the equation
  11S +11L = 220

There are a number of ways to solve a pair of equations. One is to graph them. The graph shows the costs to be ...
  The cost of a small box of oranges is $7.
  The cost of a large box of oranges is $13.

Maya spent her allowance on playing an arcade game a few times and riding the Ferris wheel more than once.
goldfiish [28.3K]
<span>To write a two-variable equation, you would first need to know how much Maya’s allowance was. Then, you would need the cost of playing the arcade game and of riding the Ferris wheel. You could let the equation be cost of playing the arcade games plus cost of riding the Ferris wheel equals the total allowance. Your variables would represent the number of times Maya played the arcade game and the number of times she rode the Ferris wheel. With this equation you could solve for how many times she rode the Ferris wheel given the number of times she played the arcade game.</span>

What is the value of the expression f(-3) + 2f(-1) - f (4)<br><br> PLEASE HELP NO LINKS
Bas_tet [7]

Answer:

22

Step-by-step explanation:

Find f(-3) :

f(x) = x² + 2x for x ≤ -3

That means for those values of x, less than or equal to -3, this is the function.

So, f(-3) = (-3)² + 2(-3) = 9 - 6 = 3

Now, f(-1) :

From the given data, we see it is: f(x) = 2 (\frac{1}{3} )^{2x}

We take this because -1 lies between -3 and 4.

Now, f(-1) = 2 (\frac{1}{3} )^{2(-1)}

 => f = (-1) = 2(3)^{2} = 2 (9) = 18

For f(4) :

Clearly, the function is: f (x) = \frac{2x - 5}{x-7}

f (4) = \frac{2(4)-5}{4-7} = \frac{3}{-3} = -1

Therefore, <u>f(-3) + f(-1) - f(4) = 3 + 18 - (-1) = 3 + 18 + 1 = 22.</u>

The surface area of the cube is 54 square feet. What is the length, in feet, of one edge of the cube?​
Brut [27]

Answer:

3 ft

Step-by-step explanation:

A cube is made of 6 equal faces each of which is a square with the same side length. The surface area of the cube is the surface area of one side multiplied by 6. We know the surface area is 54 so divide this by 6.

54/6 = 9 ft^2

Since the surface must be a square, take the square root of 9 which is 3 ft. The length of one edge of the cube is 3 ft.
