Two numbers whose sum is 44 and whose product is a maximum
Mashcka [7]

Answer:

x = y = 22

Step-by-step explanation:

It would help to know your math course. Do you know any calculus? I'll assume not.

Equations

x + y = 44

Max = xy

Solution

y = 44 - x

Max = x (44 - x)                    Remove the brackets

Max = 44x - x^2                   Use the distributive property to take out - 1 on the right.

Max = - (x^2 - 44x )               Complete the square inside the brackets.

Max = - (x^2 - 44x + (44/2)^2 ) + (44 / 2)^2 . You have to understand this step. What you have done  is taken 1/2 the x term and squared it. You are trying to complete the square. You must compensate by adding that amount on the end of the equation. You add because of that minus sign outside the brackets. The number inside will be minus when the brackets are removed.

Max = -(x - 22)^2 + 484

The maximum occurs when x = 22. That's because - (x - 22) becomes 0.

If it is not zero it will be minus and that will subtract from 484

x + y = 44

xy = 484

When you solve this, you find that x = y = 22 If you need more detail, let me know.

(2, 7) and (-4,1)<br> In point slope form
GREYUIT [131]

Answer:

First you need to find the slope with this equation.

<h3>m=\frac{y2-y1}{x2-x1}  m=slope</h3><h3>m=\frac{1-7}{-4-2}</h3><h3>m=\frac{-6}{-6}</h3><h3>m=1</h3>

So the point slope form formula is:

<h3>y-y1=m(x-x1)</h3><h3>y-7=1(x-2)</h3><h3>y-7=x-2</h3>

y=x-2+7\\y=x+5This is the point slope form.I hope this help.

Please give me the brainliest

Solve the inequality
wariber [46]
6y+1>=10
Subtract 1 from both sides
6y>=9
Divide 6 on both sides so that the only thing remaing on the left side is the variable y.
Final Answer: y>= 1.5 or 1 1/2

If - 7 = 9 + x, then -3x + 5 = ?
Vikentia [17]

Answer:

53

Step-by-step explanation:

At first,

- 7 = 9 + x

By subtracting 9 from both sides, we get

-7-9=9+x-9

-16=x

Now,

By substituting the value of x in -3x + 5 , we get

-3x + 5

-3×(-16)+5

48+5

53
