Answer:

7

Step-by-step explanation:

(15x + 5) and (-2 + 16x) represents the measures of corresponding angles.

Measures of corresponding angles are equal.

Therefore,

- 2 + 16x = 15x + 5

16x - 15x = 5 + 2

x = 7

True or False?In Exercise,determine whether the statement is true or false given that f(x) = In x.if it is false,explain why or
EastWind [94]

Answer:

False

Step-by-step explanation:

This is false. We can disprove this by plugging in the number into the function f(x) = lnx

f(0) = ln0

Since e^{- \infty} = 0, ln0 = -\infty

This is not 0 so f(0) cannot be equal to 0, thus disproving the statement.

Identify an equation in point-slope form for the line perpendicular to
Alchen [17]

Answer:

y - 9 = \frac{1}{2}(x +3)

Step-by-step explanation:

Given

Function; y = -2x + 8

Required

Find an equation perpendicular to the given function if it passes through (-3,9)

First, we need to determine the slope of:  y = -2x + 8

The slope intercept of an equation is in form;

y = mx + b

<em>Where m represent the slope</em>

Comparing  y = m_1x + b to y = -2x + 8;

We'll have that

m_1 = -2

Going from there; we need to calculate the slope of the parallel line

The condition for parallel line is;

m_1 * m_2 = -1

Substitute m_1 = -2

(-2) * m_2 = -1

Divide both sides by -2

m_2 =\frac{ -1}{-2}

m_2 =\frac{1}{2}

The point slope form of a line is;

y - y_1 = m_2(x - x_1)

Where (x_1,y_1) = (-3,9) and m_2 =\frac{1}{2}

y - y_1 = m_2(x - x_1)becomes

y - 9 = \frac{1}{2}(x - (-3))

Open the inner bracket

y - 9 = \frac{1}{2}(x +3)

<em>Hence, the point slope form of the perpendicular line is: </em>

<em />y - 9 = \frac{1}{2}(x +3)<em />

If p(x)=2x^2 -4 and q(x)=x-3, what is (p*q)(x)
Natasha_Volkova [10]

Answer:

2x^3 - 6x^2 - 4x + 12.

Step-by-step explanation:

(p*q) (x)  = (2x^2 - 4)(x - 3)

= 2x^3 - 6x^2 - 4x + 12.

Identify the type of function represented by f(x)= 3/8(4)^x
Ludmilka [50]

Answer:

It is an exponential function

Step-by-step explanation:

We have the following function:

f (x) = 3/8 (4) ^ x

The function is of the form:

f (x) = A (b) ^ x

Where,

A: initial amount

b: growth factor (b> 1)

x: time variable.

Answer:

f (x) = 3/8 (4) ^ x

It is an exponential function of the form:

f (x) = A (b) ^ x
