Answer:

False.

Step-by-step explanation:

The formula of a slope is

$\frac{y_2-y_1}{x_2-x_1}$

However, the question says the wrong formula. This makes the answer false.

Find the measure of the exterior angle.

MaRussiya [10]

Answer:

$120 \degree$

Step-by-step explanation:

The exterior angle in a triangle is equal to the sum of the interior opposite angles in a triangle

Therefore,

$90 + x = 4x$

Now solve for x

$90 + x = 4x \\ 90 = 4x - x \\ 90 = 3x \\ \frac{90}{3} = \frac{3x}{3} \\ 30 \degree = x$

Now let's solve for the exterior angle

$4x \\ 4 \times 30 \\ 120 \degree$

Hope this helps you.

Let me know if you have any other questions :-)

|x+3|, if x>5

bearhunter [10]

Answer:

Step-by-step explanation:

Suppose x+3 < 0. Subtract 3 from both sides of the inequality.

x < -3

So, x+3 is negative when x < -3. When x>5,

x+3 > 8, which is positive, so the absolute value function has no effect.

|x+3| > 8

Which is equivalent to x^3 y^-7

PilotLPTM [1.2K]

For this case we must find an expression equivalent to:

$x ^ 3 * y ^ {- 7}$

By definition of power properties we have to meet:

$a ^ {-1} = \frac {1} {a ^ 1} = \frac {1} {a}$

Then, we can rewrite the expression as:

$x ^ 3 * \frac {1} {y ^ 7} =\\\frac {x ^ 3} {y ^ 7}$

Answer:

$\frac {x ^ 3} {y ^ 7}$

Please help me solve the expression for “n”

Bingel [31]

Answer:

n = 2

Step-by-step explanation:

In order for the ratio to have a value of 1, the sum of exponents in the numerator must equal the sum of exponents in the denominator:

n + 7 = 9

n = 9 -7 . . . . . . subtract 7 from both sides of the equation

n = 2

___

Alternatively, you can simplify the given expression:

$\dfrac{9^n(9^7)}{9^9}=1=\dfrac{9^n}{9^2}$

Hopefully, it is clear to you that the value of n must be 2 in order to make the numerator equal to the denominator.
