Answer:

total money = 50

money remained = 28

money can be used = 50 - 28 = 22

Max item that can be purchased = 22 ÷ 4 = 5

+ 2 remainder.

items buy = 5

total money left = 30

Answer:

5 gifts

Step-by-step explanation:

Given information:

  • Cost of one gift = $4
  • Total money = $50
  • Money left after purchasing gifts = at least $28

Let x = greatest number of gifts James can buy

Create an inequality with the given information:

⇒ 50 - 4x ≥ 28

<u>Solve the inequality</u>

Add 4x to both sides:

⇒ 50 - 4x + 4x ≥ 28 + 4x

⇒ 50 ≥ 28 + 4x

Subtract 28 from both sides:

⇒ 50 - 28 ≥ 28 + 4x - 28

⇒ 22 ≥ 4x

Divide both sides by 4

⇒ 22 ÷ 4 ≥ 4x ÷ 4

⇒ 5.5 ≥ x

⇒ x ≤ 5.5

We must <u>round down</u> to 5 as if James buys 6 gifts, he will only have $26 remaining.  Therefore, the greatest number of gifts James can buy is <u>5 gifts</u>.

How do you solve 1/3x = 20 to find x
Alex
1/3x=20

1st step do the opposite of 1/3x to get it by itself. So you would do 1/3x *3/1 than you would do 3/1 *20. What you do to that side you do to the other.

2nd step 20*3=60

3rd You can check your answer by doing 1/3 *60=20

I plugged the answer in the variable to Check it

HELP WITH MATHHHH PLEASE

The vertex is at the point (0,0) and the focus at the point (0, 1/8). This is given to us. Both the vertex and focus are separated by a vertical distance in the positive direction.

This means that the parabola opens upward. The vertex form of the equation for a parabola that opens upward is:

y = a(x - h)^2 + k, where the point

(h, k) is the vertex of the parabola.

Plug the vertex given into the above equation.

y = a(x - 0)^2 + 0

y = ax^2 + 0

y = ax^2

What is a?

Note: a = 1/(4f), where f is the distance from the vertex to the focus or simply as given in the focus point above 1/8.

Let f = 1/8

a = 1/4(1/8)

a = 1/(1/2)

a = 2

The equation we want is

y = 2x^2.

f(x) = 2x^2

Choice A is the answer.
