What is the multiplicative rate of change for the exponential function graphed to the left?

The true statement about the function which is represented by this graph is: D. the function has an inverse because it passes the horizontal line test.

The horizontal line test states that if the graph of function (f) is intersected by any horizontal line more than once, then, the function (f) doesn't have an inverse.

Conversely, if the graph of function (f) isn't intersected by any horizontal line more than once, then, the function (f) has an inverse.

By critically observing the graph of the given function (f) shown in the image attached below, we can logically deduce that it has an inverse because it passed the horizontal line test.

Answer: The values are a = 4, b = 2, c = 16, d = 9

simplified further

c = 16

d = 9

The option that represents the answers for 6, 8, 10, and 14 is the second option-   31, 41, 51, 71

From the question, we are to determine the option that represents the answer for pictures 6, 8, 10, and 14

In the given diagram,

The first picture requires 6 matches

The 2nd picture requires additional 5 matches

the 3rd  picture requires additional 5 matches

and so on

That is

1 → 6

2 → 6 + 5 = 11

3 → 11 + 5 = 16

4 → 16 + 5 = 21

5 → 21 + 5 = 26

6 → 26 + 5 = 31

7 → 31 + 5 = 36

8 → 36 + 5 = 41

9 → 41 + 5 = 46

10 → 46 + 5 = 51

11 → 51 + 5 = 56

12 → 56 + 5 = 61

13 → 61 + 5 = 66

14 → 66 + 5 = 71

Hence, the option that represents the answers for 6, 8, 10, and 14 is the second option-   31, 41, 51, 71

A midpoint of a line segment implies a point on the line that is equidistant to its two ends. So that the required proof is shown below:

Given: line segment MN

           x, the midpoint of MN

           MX = RX

Then;

MX = XN (midpoint property of a line)

So that,

MN = MX + XN

      = MX + MX (since XN = MX)

MN = 2MX

Thus,

MX = XN = RX (given that MX = RX)

Therefore, it can be concluded that;

XN = RX

The rectangle's area decreased by 19%.

Length = L

Breadth = B

Original area = L x B

New area = A = L x (1 + 25%) x B x (1 - 25%)

A = L x B x 0.25 x 0.75 = L x B x 1.05

Therefore the area of the rectangle has decreased by 19%.

To find the location of a rectangle, multiply its width by means of its height. If we understand the sides of the rectangle which are different lengths, then we have each the height and the width.

The perimeter P of a rectangle is given through the system, P=2l+2w, wherein l is the period and w is the width of the rectangle. The area A of a rectangle is given by means of the method, A=lw, in which l is the duration and w is the width.

Step-by-step explanation:

the equation of parabola in vertex form is

y = a(x - h)² + k

where (h, k ) are the coordinates of the vertex and a is a multiplier.

here (h, k ) = (3, 1 ) , then

y = a(x - 3)² + 1

to find a substitute any other point on the graph into the equation.

using (0, 7 )

7 = a(0 - 3)² + 1 ( subtract 1 from both sides )

6 = a(- 3)² = 9a ( divide both sides by 9 )

[tex]\frac{6}{9}[/tex] = [tex]\frac{2}{3}[/tex] = a

y = [tex]\frac{2}{3}[/tex] (x - 3)² + 1 ← in vertex form

------------------------------------------------------

the equation of a parabola in factored form is

y = a(x - a)(x - b)

where a, b are the zeros and a is a multiplier

here zeros are - 1 and 3 , the factors are

(x - (- 1) ) and (x - 3), that is (x + 1) and (x - 3)

y = a(x + 1)(x - 3)

to find a substitute any other point that lies on the graph into the equation.

using (0, - 3 )

- 3 = a(0 + 1)(0 - 3) = a(1)(- 3) = - 3a ( divide both sides by - 3 )

1 = a

y = (x + 1)(x - 3) ← in factored form

Hello,

   3x - 11 > 7x + 9

⇔ -11 - 9 > 7x - 3x

⇔ - 20 > 4x

⇔ -20/4 > 4x/4

⇔ - 5 > x

⇔ x < - 5

The solution to the inequality 3x - 11 > 7x + 9 is x ∈ (-∞, 5) the graph is shown in the picture.

It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.

It is given that:

The inequality is:

3x - 11 > 7x + 9

After simplification:

3x - 7x > 9 + 11

-4x > 20

-x > 5

Multiplying by a negative sign on both sides:

x < -5

The number line can be defined as the representation of the numbers on a straight line that goes infinitely on both sides.

After plotting on the number line:

x ∈ (-∞, -5)

Thus, the solution to the inequality 3x - 11 > 7x + 9 is x ∈ (-∞, 5) the graph is shown in the picture.

Explanation:

[tex]\sf \rightarrow log(3x) + log(x + 4) = log(15)[/tex]

Rule: log(a) + log(b) = log(ab)

[tex]\sf \rightarrow log(3x(x + 4)) = log(15)[/tex]

cancel out log on both sides

[tex]\sf \rightarrow 3x(x + 4) = 15[/tex]

relocate constant variable

[tex]\sf \rightarrow 3x^2 + 12x -15 = 0[/tex]

take 3 as a common factor

[tex]\sf \rightarrow 3(x^2 + 4x -5) = 0[/tex]

divide both sides by 3

[tex]\sf \rightarrow x^2 + 4x -5 = 0[/tex]

middle term split

[tex]\sf \rightarrow x^2 + 5x -x-5 = 0[/tex]

factor common terms

[tex]\sf \rightarrow x(x + 5) -1(x+5)= 0[/tex]

collect into groups

[tex]\sf \rightarrow (x-1)(x+5)= 0[/tex]

set to zero

[tex]\sf \rightarrow x-1 = 0 , \ x+5= 0[/tex]

relocate variables

[tex]\sf \rightarrow x = 1, \ x = -5[/tex]

There must be a positive solution for log, so the solution is only x = 1

Answer:

[tex]x=1[/tex]

Step-by-step explanation:

Given:

[tex]\log (3x)+\log(x+4)=\log (15)[/tex]

As the logs have no base, assume that the base is 10.

[tex]\textsf{Apply log Product law}: \quad \log_ax + \log_ay=\log_axy[/tex]

[tex]\implies \log_{10} (3x)+\log_{10}(x+4)=\log_{10} (15)[/tex]

[tex]\implies \log_{10} \left(3x(x+4)\right)=\log_{10} (15)[/tex]

Expand the brackets:

[tex]\implies \log_{10} \left(3x^2+12x\right)=\log_{10} (15)[/tex]

[tex]\textsf{Apply the log Equality law}: \quad \textsf{if }\: \log_ax=\log_ay\:\textsf{ then }\:x=y[/tex]

[tex]\implies 3x^2+12x=15[/tex]

Subtract 15 from both sides:

[tex]\implies 3x^2+12x-15=0[/tex]

Factor out the common term 3:

[tex]\implies 3(x^2+4x-5)=0[/tex]

Divide both sides by 3:

[tex]\implies x^2+4x-5=0[/tex]

Split the middle term:

[tex]\implies x^2+5x-x-5=0[/tex]

Factorize the first two terms and the last two terms separately:

[tex]\implies x(x+5)-1(x+5)=0[/tex]

Factor out the common term (x + 5):

[tex]\implies (x-1)(x+5)=0[/tex]

Therefore:

[tex]x-1=0 \implies x=1[/tex]

[tex]x+5=0 \implies x=-5[/tex]

As logs cannot be taken of negative numbers, [tex]x=-5[/tex] is an extraneous solution.  Therefore, the only valid solution is:  [tex]x=1[/tex]

Step-by-step explanation:

First draw a line. I will put it in an attachment so you can see the line.

Now choose to points on the line to use the slope formula.

(0,15) and (3,13).

Slope formula: [tex]\frac{y2-y1}{x2-x1}[/tex]

Plug in the information needed using the two points chosen.

[tex]\frac{13-15}{3-0}=\frac{-2}{3}[/tex]

The slope is [tex]\frac{-2}{3}[/tex].

Now use point-slope formula.

Point-slope formula: y-y1=m(x-x1)

y-15=[tex]\frac{-2}{3}[/tex](x-0)

y-15=[tex]\frac{-2}{3}[/tex]x-0

Subtract 15 from both sides.

Answer:

y = - 2x + 3

calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, 3 ) and (x₂, y₂ ) = (1, 1 )
