Answer:

x=10

Step-by-step explanation:

Make 2x the only variable on the left side of the equation. Do that by taking 3 and 5 to the left. Note: if you move/transpose any number the sign must change.

2x = 18+5-3

2x=20

Divide both sides of the equation by 2 to make x the only variable left.

x=10

Answer:

Step-by-step explanation:

Using the domain, it is found that x = -8 is excluded for the product.

The domain of a function is the set that contains all possible input values.

In this problem, there are two fractions, and the points outside the domain, that is, the roots of the denominators, are excluded.

For the first fraction, they are:

[tex]3x^2 + 6x = 0[/tex]

[tex]3x(x + 2) = 0[/tex]

[tex]3x = 0 \rightarrow x = 0[/tex]

[tex]x + 2 = 0 \rightarrow x = -2[/tex]

Hence, x = -2(not an option) is excluded.

For the second fraction, the roots of the denominator are:

[tex]x^2 + 11x + 24 = 0[/tex]

Which is a quadratic equation with coefficients [tex]a = 1, b = 11, c = 24[/tex], hence:

[tex]\Delta = b^2 - 4ac = 11^2 - 4(1)(24) = 121 - 96 = 25[/tex]

[tex]x_1 = \frac{-b - \sqrt{\Delta}}{2a} = \frac{-11 - 5}{2} = -8[/tex]

[tex]x_2 = \frac{-b + \sqrt{\Delta}}{2a} = \frac{-11 + 5}{2} = -3[/tex]

x = -3 can be factored with the numerator of the first fraction, so only x = -8 is excluded.

Answer:

1200

Step-by-step explanation:

A difference of 2 squares factors in general as

a² - b² = (a - b)(a + b) , then

103² - 97²

= (103 - 97)(103 + 97)

= 6 × 200

= 1200

The correct answer is 1200.

Where one perfect square is subtracted from another, is called a difference of two squares. It arises when (a − b) and (a + b) are multiplied together. This is one example of what is called a special product.

A difference of 2 squares factors in general is written as

a² - b² = (a - b)(a + b) , then

103² - 97²

= (103 - 97)(103 + 97)

= 6 × 200

= 1200

Answer:

r — 7.5 > -8

Step-by-step explanation:

r — 7.5 < —8 is r < - 0.5

—r — 7.5 > -8 is r < 0.5

—r — 7.5 > 8 is r < -15.5

r — 7.5 > -8 is r > -0.5

If you replace r with 17 the only that would be true is r — 7.5 > -8 cause 17 - 7.5 > -8 = 9.5 > -8 making the sentence true.
