The graph of y = f(x) has a maximum point at (-2, 4).

Answer:

(2,4).

Step-by-step explanation:

Graph of y = f(-x).

The values of x in f(-x) assume the values of -x in f(x).

For example, f(-2) in f(x) is f(2) in f(-x), and f(2) in f(x) is f(-2) in f(-x).

b) Write down the coordinates of the maximum point of the graph of y = f(-x).

In f(x), we have that x = -2. So in f(-x), it will be x = 2. y remains unchanged. So

(2,4).

What is the solution to the compound inequality 3x-8>-5 and 2x-7<5
-BARSIC- [3]

Answer:

<h2>1 < x < 6 ⇒ x ∈ (1, 6)</h2>

Step-by-step explanation:

3x - 8  > -5              <em>add 8 to both sides</em>

3x > 3        <em>divide both sides by 3</em>

x > 1

2x - 7 < 5            <em>add 7 to both sides</em>

2x < 12          <em>divide both sides by 2</em>

x < 6

From x > 1 and x < 6 we have the solution 1 < x < 6 ⇒ x ∈ (1, 6)

IT IS DUE AT 11:59PM. PLEASE HELP!!!!

Hello from MrBillDoesMath!

Answer:   b = 4, h = 13

Discussion:

For a triangle with base b" and height "h, the area formula is

A=  (1/2)bh.

In our case A = 26, h = 5b-7, so

26 = (1/2) b (5b-7).  Multiply both sides by 2:

26*2 = b(5b-7) =>

52 = b(5b-7)  =>

52 = 5b^2 - 7b =>           (subtract 52 from both sides)

5b^2 - 7b - 52 = 0.   This factors as follows:

(b - 4) (5 b + 13) = 0        (use quadratic formula to find this)

so b = 4 and h = 5b -7 = 5*4 - 7 = 13


Thank you,

MrB

Graph the line that has a slope of 1/4 and includes the point (0,8)
Alex787 [66]

Step-by-step explanation:

Equation of line:

y = mx + c

where m is the slope

and c is the y-intercept (the value of y when x = 0)

In this case, given the slope = 1/4

and y-intercept is 8 (from the point (0,8))

The equation of the following line is:

y =  \frac{1}{4} x + 8

Where are the asymptotes for the following function located? f(x)= 7/ x^2-2x-24
Zarrin [17]
Factor the demoniator:-

x^2 -2x - 24 = (x - 6)(x + 4)

the asymptotes occurs when denominator = 0

so here they are  the vertical lines x = 6 and x = -4
