How does the graph of the transformed function g(x) = log7(3x-9) compare to the graph of its parent function f(x) = log7x

Answer:

your answer is C

Step-by-step explanation:

by elimination B is not possible as the graph shows a cubic shape B has no cubic terms, D is not possible because the graph shows a translation on X axis and D represents a translation in Y axis, and A is not possible because when X=0 the value of Y must be -64 and A doesn't comply to that.

Answer:

C

Step-by-step explanation:

the graph has 3 zero solutions (values of x with y = 0).

therefore it has to be of 3rd degree (3 is the max. exponent of x).

that eliminates B, because it is only of 2nd degree.

when x = 0, y is a little bit below -60 but above -80.

but y is negative.

that eliminates A, because when x = 0, y = +64.

for x = -8, y has to be 0 too.

that eliminates D, because for x = -8, y = -8³ - 64 = -512 - 64 = -576

and not 0.

so, C must be correct.

for x = 0, y = -64

for x = -8, y = -8³ + 6×-8² - 24×-8 - 64 =

= -512 + 6×64 + 192 - 64 =

= -512 + 384 + 192 - 64 = 0

for x = -2, y = -2³ + 6×-2² - 24×-2 - 64 =

= -8 + 6×4 + 48 - 64 =

= -8 + 24 + 48 - 64 = 0

for x = 4, y = 4³ + 6×4² - 24×4 - 64 =

= 64 + 6×16 - 96 - 64 =

= 64 + 96 - 96 - 64 = 0

all fits.

The domain can be best described using interval notation. The domain is [1,∞].

A continuous function is graphed here. The function is continuous only on  where it is defined. That is, the graph of the function does not have any discontinuities from 1 to infinity.

The domain of a function is the x-values for which the function is defined. That is for such x-values, the function will attain some y-value, which is called the function value. This function values corresponding to each x-value sketches the graph.

From the figure, the graph is started from x = 1 and is extended to infinity.

So it is better to express the domain in an interval form.

Graph of the function is a curve. So the domain is [1,∞].

A unit rate means a quantity at a rate of one of something.

The number of miles Sara can drive on 12.5 gallons of gas is 281.25 miles.

Option D is the correct answer.

A unit rate means a quantity at a rate of one of something.

It is written with a denominator of one. 

We have,

Sara drives 171 miles on 7.6 gallons of gas.

This can be written as:

171 miles = 7.6 gallons

Multiply 12.5/7.6 on both sides.

12.5/7.6 x 171 miles = 12.5/7.6 x 7.6 gallons

281.25 miles = 12.5 gallons

Thus,

The number of miles Sara can drive on 12.5 gallons of gas is 281.25 miles.

Answer: 25%

Explanation:

Probability is expressed as

number of favorable outcomes/number of total outcomes

From the information given, the spinner has 4 equal spaces. Thus,

number of total outcomes = 4

number of favorable outcomes = number of blue spaces = 1

Thus,

the probability of spinning the spinner and having it land on blue = 1/4 x 100

the probability of spinning the spinner and having it land on blue = 25%

The angle addition postulate is the best justification for m∠XPD + m∠DPE = m∠XPE.

An angle bisector is a line segment that divides an angle into two equal parts.

The angle addition postulate states, if a line segment is in between an angle sum of two smaller angles created by the line segment, is equal to the measure of the larger angle.

We have an ∠XPE that is divided by a line segment PD which creates two smaller angles ∠XPD and ∠DPE.

∴ By angle addition postulate m∠XPD + m∠DPE = m∠XPE.

The number of cheeseburgers sold was three times the number of hamburgers sold then 79 hamburgers and 237 cheeseburgers were sold on Sunday.

Let h be the number of hamburgers

c be the number of cheeseburgers

A local hamburger shop sold a combined total of 316 hamburgers and cheeseburgers. The number of cheeseburgers sold was three times the number of hamburgers sold.  

h + c = 316

c = 3h

h + 3h = 316

simplifying the above equation, we get

⇒ 4h = 316

Dividing both sides of the equation by 4, we get

⇒ 4h / 4 = 316 / 4

⇒ h = 79

Therefore, hamburgers were sold on Saturday is 79.

The number of cheeseburgers sold was three times the number of hamburgers sold then

c = 3h

substitute the value of h in the above equation, we get

⇒ c = 237

Therefore, 79 hamburgers and 237 cheeseburgers were sold on Sunday.

Given:

The graph shows the XY plane where x shows the number of T shirts bought and Y shows the number of stickers received.

The plotted points on the graph have the coordinates:

Clearly, we can see the y coordinate is double of x coordinate here, so the equation of graph shown will be : y = 2x

Now we will check the points given in tables in the options if they satisfy this equation or not.

Check option (F),we get:

Which doesnot satisfy the equation y=2x hence, option F is wrong.

Now chcek option G ,

These points clearly satisfy y= 2x, hence,

Option (G) is correct.

Similarly, if we check option (H) and (I) they will not satisfy the equation, Hence , option (G) is only correct.

Answer:

Step-by-step explanation:

g

u

Looking at f(x) and g(x), we can see that g(x) is made by f(x) multiplied by -6.

Since the function was multiplied by a negative value, that means we had a reflection over the x-axis.

Also, if the function was multiplied by a constant value, that means we had a vertical stretch by a factor equal to the absolute value of the constant.

Therefore the correct options are A and D.

The 28th term of the given arithmetic sequence is 219

any arithmetic sequence can be solved once we identify the aa1 term and the an term because then we have to simply find the common difference and solve further by substituting the value in the below mentioned equation.

Given the arithmetic sequence = 3,11, 19, 27

a₁ = 3

a₂ = 11

a₃ = 19

a₄ = 27

the common difference or d = a₂ - a₁

this implies d = 11 - 3 = 8

Therefore the 28th term of the given arithmetic sequence is

a₂₈ = a₁ + ( n - 1 ) d

a₂₈ = 3 + ( 28 - 1 ) 8

     = 3 + 27 × 8

     = 3 + 216

     = 219

First we need to look at the change of signal of the function (it changes from √x to -√x).

This change of signal means the function was reflected over the x-axis.

Then, the value of -3 was added to the function.

An addition of -3 in the function means a translation of 3 units down.

So the transformations from m(x) to p(x) are:

Recall the following:

A ∩ C (read as A intersection C) - are members that are common to both set A and set C.

A ∪ C (read as A union C) - are members that are in set A or set C or both, combining the members of all sets.

C' (read as C complement) - are members that are not in the universal set.

Since what we are about to find is A ∪ C', let's first determine the members of C'.

We get,

C' = {1, 2, 3, 4}

A = {1,2,3,4,5}

Therefore, AUC' = {1,2,3,4,5}.

The value of cos (A - B) will be 33/65.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The values are;

cos A = 24/25

And, sin B = 63/65

Now,

cos (A - B) = cos A cos B + sin A sin B

Since, cos A = 24/25

So, sin A = 7/25

And, sin B = 63/65

So, cos B = 16/65

Substitute all the values, we get;

cos (A - B) = cos A cos B + sin A sin B

               = 24/25 x 16/65 + 7/25 x 63/65

              = 384/1625 + 441 / 1625

              = 825 / 1625

              = 33/65

Given:

Since the bags are distributed according to the proportion of their ages, then, we say

5 bags x 16 candies =80 candies.

80 / 4 = 20 candies per child

Given that his 4-year-old sister gets 20 -12 = 8 candies, then:

8/4 = 2 candies per year for each child's age.

Given that Cameron will gain 20 + 2 =22 candies, then:

22 / 2 = 11 years is Cameron's age.

22 candies of Cameron + 8 candies for youngest sister=30

80 - 30 = 50 candies for the remaining older children.

Since Cameron is the 2nd youngest, it means the remaining 2 siblings must be 12 and 13 years respectively:

So that: 12 x 2 = 24 candies for the 3rd oldest

And 13 x 2 = 26 candies for the oldest child. So, the total allocations of all the candies would be:
