Help me please thanks

Answer:

y=4/5x

Step-by-step explanation:

If you multiply the x value of 10, substitute it into the equation. Using the equation y=4/5x, you will get the y value of 8.

When you substitute the x value of 5 into the equation. You will get 4.

You do this for the rest of the x values and will get the correct y values.

Answer:

Step-by-step explanation:

Y = k1/x

4 = k 1/2.5

2.5 x 4 = k

10 = k

Now using this equation we will find the other answers

A) find y when x = 20

Y = k 1/x

Putting values

= 10(1/20) = 1/2 = 0.5

B) find x when y = 5

Y = k 1/x

Putting values

5 = 10 1/x

5x = 10

x = 10/5 = 2

Step-by-step explanation:

g(x)=5/4(2)^x

Make a table of points. Choose any 5.

X. Y

0 5/4. 5/4*2^0

1. 5/2. 5/4*2^1

2. 5. 5/4*2^2

3. 10. 5/4*2^3

4. 20. 5/4*2^4

The x, y table above are x, y coordinates to plot. To the right is just solving the equation with different values for the power of 2

Answer:

y = [tex]\frac{9}{x^2}[/tex]

Step-by-step explanation:

Given y is inversely proportional to x² then the equation relating them is

y = [tex]\frac{k}{x^2}[/tex] ← k is the constant of proportion

To find k use an ordered pair from the table

Using x = 3 when y = 1 , then

1 = [tex]\frac{k}{3^2}[/tex] = [tex]\frac{k}{9}[/tex] ( multiply both sides by 9 )

9 = k

y = [tex]\frac{9}{x^2}[/tex] ← equation of proportion

**If the picture is sideways, use the rotate button at the top right.

Answer:

12

Step-by-step explanation:

Essentially, 60 and the 5 us must be equal:

60=5u

Divide both sides by 5 to solve for u but keep the equation balanced.

12=u

Answer:

the answer is 12

Answer:

Kendra will put 7 games on each of the 5 shelves, 35 in total. 2 of the games will be put into the box.

Step-by-step explanation:

Answer:

First since 2 of the options ask for the width of BM lets solve for it using the Pythagorean theorem for both sides of point L:

a² + b² = c²

30² + b² = 50²

b² = 50² - 30²

b² = 1600

b = 40    Line BL = 40 ft

Since the ladder is 50 feet it is the same length on the other side as well

a² + b² = c²

40² + b² = 50²

b² = 50² - 40²

b² = 900

b = 30        line LM is 30 ft

SO line lm + line bl = 30 + 40 = 70 ft

A is true because ^

B isn't true because as we solved for earlier, BL is 40

C is true because line LM is in fact 30 ft as we solved for

D is not true because as we said earlier BM is 70

E is true because the same ladder was used on both sides of the street

Step-by-step explanation:

The width of the street, BM, is 70 feet. The ground distance of the ladder from building M is 30 feet. The length of KL is 50 feet.

Pythagoras's theorem states that in a right-angled triangle, the square of one side is equal to the sum of the squares of the other two sides.

First, because two of the possibilities require the width of BM, let us solve for it using the Pythagorean theorem for both sides of point L.:

a² + b² = c²

30² + b² = 50²

b² = 50² - 30²

b² = 1600

b = 40  

So, Line BL = 40 ft

So because the ladder is 50 feet long, it is also the same length on the other side.

a² + b² = c²

40² + b² = 50²

b² = 50² - 40²

b² = 900

b = 30        

So, line LM is 30 ft

So line lm + line bl = 30 + 40 = 70 ft

Hence, the true statements are options (A), (C), and (E).

Answer: Line 3

Step-by-step explanation:

Answer:

3

Step-by-step explanation:

The  f^-1 notation indicates you need to find the inverse of the function

y=2x+1

x=2y+1

Exchange the x & y variables. Note this is what accomplishes that reflection across the line y = x

7=2y+1

-2y=1-7

-2y=-6

Divide both side of the equation by -2

negative divide negative is positive so

y=3

Answer:

a) 216 b)1.5 c) 2.25

Step-by-step explanation:

The form is y = kx

Replace y and x:

50 = k(5)

Solve for k by dividing both sides by 5

K = 10

Answer:

The mass of the meat when thawed is 7.72 kg (0.28 kg is lost)

Step-by-step explanation:

From the question, we are told that the weight loss amount is 8% of its initial weight

The mass lost here when thawed will be;

8/100 * 3.5 = 0.28 kg

So the mass of the joint will be;

8-0.28 = 7.72 kg
