Answer:

12−(−5) = 17

Step-by-step explanation:

The given expression is

12-(-5)

We need to find the value of given expression using a number line.

Two numbers are 12 and -5.

Plot these two numbers on the number line.

Now, start form -5 and jump up to 12 on the number line and count the jumps, then the number of jumps is the answer.

From below figure it is clear that the number of jumps between -5 and 12 is 17.

Therefore, the value of given expression is 17.

Find two positive numbers satisfying the given requirements. the product is 192 and the sum of the first plus three times the se
Zepler [3.9K]
<h3>Given</h3>

Two positive numbers x and y such that xy = 192

<h3>Find</h3>

The values that minimize x + 3y

<h3>Solution</h3>

y = 192/x . . . . . solve for y

f(x) = x + 3y

f(x) = x + 3(192/x) . . . . . the function we want to minimize

We can find the x that minimizes of f(x) by setting the derivative of f(x) to zero.

... f'(x) = 1 - 576/x² = 0

... 576 = x² . . . . . . . . . . . . multiply by x², add 576

... √576 = x = 24 . . . . . . . take the square root

... y = 192/24 = 8 . . . . . . . find the value of y using the above equation for y

The first number is 24.

The second number is 8.

Explain why each table determine if y is proportional to x .
lesya692 [45]

Answer:

see explanation

Step-by-step explanation:

If y is proportional to x then the equation relating them is

y = kx ← k is the constant of proportion

To find k divide both sides by x

k = \frac{y}{x}

This value must be constant for all ordered pairs, thus

k = \frac{4}{6} = \frac{2}{3}

k = \frac{6}{9} = \frac{2}{3}

k = \frac{8}{12} = \frac{2}{3}

k = \frac{2}{3}

Since k is constant for all ordered pairs then y is proportional to x
