Answer:

h = 84

3 = 87 - h

h + 3 = 87 (Add h to both sides)

h = 84 (Subtract 3 from both sides)

Laney is ordering books while she is on summer vacation. Reader's Book Club charges $4.00 per book and requires a one-time membe

bonufazy [111]

Answer:

$12 + 4b < 7.50b$

Step-by-step explanation:

Given

Reader' Book Club

$Membership = \$12$

$Book = \$4.00$ per book

Perfect Page

$Book = \$7.50$ per book

Required

Write an inequality to represent the situation

Represent the number of books with b

First, we need to write an expression for Reader's book

This is:

= Membership + Books Read

$12 + 4b$

For Perfect Page

This is

= Books Read

$7.50b$

For Reader's club to be less than Perfect Page, we have:

$12 + 4b < 7.50b$

HELP DUE SOON! x = ?? degrees

rjkz [21]

Answer:

Step-by-step explanation:

Tricky. Very neat.

You are missing the minor arcAC and you need it, but don't fret. It can be found.

The formula for this is x = 1/2(Major Arc(235) - Minor Arc(see below) )

The minor arc is the supplement of x.

The minor arc is also equal to the the central angle

So the minor arc is 180 - x

x = 1/2 (235 - (180 - x) ) Remove the inside brackets

x = 1/2 (55 + x ) Remove the remaining brackets

x = 1/2 *55 + 1/2x Subtract 1/2x from both sides

1/2 x = 27.5 Multiply both sides by 2

x = 55

What is the maximum number of possible extreme values for the function, f(x) = х2 -7x – 6?

timama [110]

Answer:

Only one extreme value of f(x) is possible.

Step-by-step explanation:

We are given the quadratic function of independent variable x which is f(x) = x² - 7x - 6 ......(1)

Now. the condition for extreme values of f(x) is $\frac{df(x)}{dx} =0$

Hence, differentiating both sides of equation (1) with respect to x, we get

$\frac{df(x)}{dx} = 2x -7$ = 0

⇒ x = 3.5.

So there is only one value of x for which f(x) has extreme value which is x = 3.5.

Therefore, only one extreme value of the given function is possible. (Answer)
