20/24

Step-by-step explanation:

let the variable be x and x-4

5/6 = x-4/x

cross multiply

5x = 6x - 24

24= x

thus, x is 24 and x-4 is 20

For a parabola with a minimum point at (3,-1), determine the equation for the function's axis of symmetry

algol [13]

Answer:

x=3

(Do not write a character less than what I have written; 3 is not the answer but x=3 is the answer.)

Step-by-step explanation:

Parabolas have a axis of symmetry; this is the line they are symmetrical about.

The line of symmetry will always go through the vertex.

Since your question says it is a function the line will be vertical and will be of the form x=a number.

The number is determine by the x-coordinate of the vertex.

I know the vertex of your problem is (3,-1) because it says that is the minimum point of the graph. The vertex of a parabola will always be it's maximum (this parabola is open down) or minimum (this parabola is open up).

So the axis of symmetry is just:

x=3.

You must actually write x=3.

3 is not the answer.

x=3 is the answer.

Little note down here:

(If it had said the parabola wasn't a function, the axis of symmetry would have been horizontal and therefore of the form y=a number where the number was the y-coordinate of the vertex.)

Chelsea and Ming are selling pies for a school fundraiser. Customers can buy blueberry pies and lemon pies. Chelsea sold 7 blueb

riadik2000 [5.3K]

Answer:

The cost of 1 blueberry is $7

The cost of 1 lemon pie is $17

Step-by-step explanation:

Given as :

The number of blueberry sold by Chelsea = 7

The number of lemon pie sold by Chelsea = 10

The number of blueberry sold by Ming = 5

The number of lemon pie sold by Ming = 1

The total selling amount of Chelsea = $219

The total selling amount of Ming = $52

Let The cost of 1 blueberry = b

And The cost of 1 lemon pie = l

Now, According to question

For Chelsea

7 b + 10 l = $219 ..................1

For Ming

5 b + 1 l = $52 .................2

Solving both equations

10×(5 b + 1 l ) - (7 b + 10 l) = 10×52 - 219

Or, 50 b + 10 l - 7 b - 10 l = 520 - 219

Or, (50 b - 7 b) + (10 l - 10 l) = 301

Or, 50 b - 7 b+ 0 = 301

Or, 43 b = 301

∴ b = $\frac{301}{43}$

I.e b = $7

So, The cost of 1 blueberry = b = $7

Put the value of b in eq 2

So, 5 × 7 + 1 l = $52

or, 35 + l = $ 52

Or, l = 52 - 35

∴ l = $17

So, The cost of 1 lemon pie = l = $17

Hence The cost of 1 blueberry is $7

And The cost of 1 lemon pie is $17 Answer
