Answer:

Number of Solutions

Most linear systems you will encounter will have exactly one solution. However, it is possible that there are no solutions, or infinitely many. (It is not possible that there are exactly two solutions.) The word unique in this context means there is a solution, and it's the only one.

Given:

I'm 3 times younger than my mom but 3 times older than my younger brother.

Mom is older than my younger brother by 40 years.

To find:

How old am I.

Solution:

Let x be the age of the younger brother.

I'm 3 times older than my younger brother. So, my age is 3x.

I'm 3 times younger than my mom. So, she is 3 times older than me and her are is 3(3x)=9x.

The difference between the age mother and younger brother is 40 years.

[tex]9x-x=40[/tex]

[tex]8x=40[/tex]

Divide both sides by 8.

[tex]x=\dfrac{40}{8}[/tex]

[tex]x=5[/tex]

Now,

My age [tex]=3x[/tex]

            [tex]=3(5)[/tex]

            [tex]=15[/tex]

Therefore, I'm 15 years old.

Answer:

To graph a linear equation in slope-intercept form, we can use the information given by that form. For example, y=2x+3 tells us that the slope of the line is 2 and the y-intercept is at (0,3). This gives us one point the line goes through, and the direction we should continue from that point to draw the entire line.

Answer:

Step-by-step explanation:

7C10 = 10!/(7!)(10-7)!

7C10 = 10!/(7!)(3!)

7C10 = (10 x 9 x 8 x 7)/(7 x 6 x 5)(6)

7C10 = (10 x 9 x 8)/6

7C10 = 720/6

7C10 = 120

Answer:

6.25% I think

Step-by-step explanation:

If Kiara sells car at $7500 and it is of $8000 then she is having a loss of 6.25%.

A percentage is the number or ratio which is expressed as a fraction of 100.

We have been given the buying value=$8000

Selling value=$7500

Loss=Buying value- selling value

=8000-7500

=$500

Percentage of loss=loss/ buying value*100

=500/8000*100

=6.25%

If we want to check our answer then we can multiply our percentage with the buying value.

=8000*6.25%

=500

Hence if Kiara sells car at $7500 and it is of $8000 then she is having a loss of 6.25%.

Step-by-step explanation:

Answer:

Step-by-step explanation:

how many shapes of size A are in B ?  

I counted 9.5

then just multiply the count * the size of A

got it?

Step-by-step explanation:

area of shape A = 3cm²

number of A shape in shape B = 9 and half

1 shape A = 3cm²

9 shape A = 3×9 = 27cm²

1 half shape A = 3 ÷ 2 = 1.5cm²

area of shape B = 27cm² + 1.5cm² = 28.5cm²

Answer:

[tex](a)[/tex] [tex]P(x) = 0.02x^2 +50x - 100[/tex]

[tex](b)[/tex] [tex]Average = 0.02x + 50 - \frac{100}{x}[/tex] and [tex]Marginal = 0.04x + 50[/tex]

[tex](c)[/tex] [tex]Average = 59.8[/tex] and [tex]Marginal = 70[/tex]

(d) See Explanation

Step-by-step explanation:

Given

[tex]p(x) = 100[/tex]

[tex]C(x) = -0.02x^2 +50x +100[/tex]

Solving (a) Profit function; P(x)

[tex]P(x) = xp(x) - C(x)[/tex]

This gives:

[tex]P(x) = x*100 - (-0.02x^2 + 50x + 100)[/tex]

[tex]P(x) = 100x + 0.02x^2 - 50x - 100[/tex]

Collect like terms

[tex]P(x) = 0.02x^2 - 50x +100x - 100[/tex]

[tex]P(x) = 0.02x^2 +50x - 100[/tex]

Solving (b): Average profit function and Marginal profit function

[tex]Average = \frac{P(x)}{x}[/tex]

This gives:

[tex]Average = \frac{0.02x^2 + 50x - 100}{x}[/tex]

Break down the fraction

[tex]Average = \frac{0.02x^2}{x} + \frac{50x}{x} - \frac{100}{x}[/tex]

[tex]Average = 0.02x + 50 - \frac{100}{x}[/tex]

[tex]Marginal = \frac{dP}{dx}[/tex]

[tex]P(x) = 0.02x^2 +50x - 100[/tex]

Differentiate

[tex]\frac{dP}{dx} = 2 * 0.02x + 50 - 0[/tex]

[tex]\frac{dP}{dx} = 0.04x + 50[/tex]

Hence:

[tex]Marginal = 0.04x + 50[/tex]

Solving (c): Average profit and Marginal profit if x = a

[tex]a = 500[/tex]

So:

[tex]x =500[/tex]

Substitute 500 for x

[tex]Average = 0.02x + 50 - \frac{100}{x}[/tex]

[tex]Average = 0.02 * 500 + 50 - \frac{100}{500}[/tex]

[tex]Average = 59.8[/tex]

[tex]Marginal = 0.04x + 50[/tex]

[tex]Marginal = 0.04*500 + 50[/tex]

[tex]Marginal = 70[/tex]

Solving (d): Interpret the values in (c)

[tex]Average = 59.8[/tex]

They make a profit of 59.8 for the first 500 items

[tex]Marginal = 70[/tex]

From the 501st item, the profit is 70

Answer:

x=0 or x=3

Step-by-step explanation:

Since it is a geometric sequence, that means term divided by previous term is the same number. Let's call that number, r.

That means we have:

(3x+1)/(2x-1)=r

(7x-1)/(3x+1)=r

Since both of the ratios are the same, then we have

(3x+1)/(2x-1)=(7x-1)/(3x+1)

Cross multiply:

(3x+1)(3x+1)=(2x-1)(7x-1)

Distribute:

9x^2+3x+3x+1=14x^2-2x-7x+1

Combine like terms:

9x^2+6x+1=14x^2-9x+1

Subtract 1 on both sides:

9x^2+6x=14x^2-9x

Subtract 14x^2 on both sides

Add 9x on both sides

-5x^2+15x=0

Factor -5x:

-5x(x-3)=0

-5x=0 when x=0 since -5(0)=0

x-3=0 when x=3 since 3-3=0
