Solve the equation for the specified variable.
Y = AD-5, for A
Help plzzzzz

The correct answer is d) f^(-1)(x) = x/3, as it represents the Inverse relationship of y = 3x.

To find the inverse of a function, we need to switch the roles of x and y and solve for the new y.

The given function is y = 3x.

To find its inverse, let's swap x and y:

x = 3y

Now, solve this equation for y:

Dividing both sides of the equation by 3, we get:

x/3 = y

Therefore, the inverse function of y = 3x is f^(-1)(x) = x/3.

Among the given options:

a) f^(-1)(x) = 1/3x

b) f^(-1)(x) = 3x

c) f^(-1)(x) = 3/x

d) f^(-1)(x) = x/3

The correct answer is d) f^(-1)(x) = x/3, as it represents the inverse relationship of y = 3x.

Yes they are equivalent.

Step-by-step explanation:

Find the least common denominator or LCM of the two denominators:

LCM of 4 and 20 is 20

Yes, we can say that the ratio 15 : 20 and 3 : 4 are equivalent.

The ratio is the number that can be used to express one quantity as a fraction of the other ones. The two numbers in a ratio can only be compared when they have the same unit.

Equivalent ratios are the ratios that are the same when we compare them.

Therefore, for ratios of 15 : 20 and 3 : 4, for them to be equivalent, they must have thesame value.

15 : 20 = 15/20

divide through by 5

= 3/4 = 3 :4

Therefore , we can say that ratios 15 : 20 and 3 : 4 are equivalent.

Answer:

5 hamburgers and 3 hot dogs

Step-by-step explanation:

D = number of hot dogs

H = number of hamburgers

D + H = 8    then  D = 8 - H

1.50D + 1.75H = 13.25

substitute for D

1.50(8-H) + 1.75H = 13.25

12-1.50H + 1.75H = 13.25

subtract 12 from each side

-1.50H + 1.75H = 1.25

0.25H = 1.25

divide both sides by 0.25

H = 5

D = 8-5

D = 3

Answer: Measure of angle 2 + measure of angle 3

Step-by-step explanation:

The expression is equivalent to is Measure of angle 4 is ''Measure of angle 2 + measure of angle 3''.

Given

A triangle has angles 1, 2, 3.

The exterior angle to angle 1 is 4, angle 2 is 5, to angle 3 is 6.

An exterior angle is an angle that is formed by one of the sides of any closed shape structure such as polygon and the extension of its adjacent side.

The,

The measure of the angle 4 is;

The expression f(x)=g(x) indicate the points in the graph where the two functions intersect, i.e. when they cross

In this graph, g(x) cuts f(x) in two points (-4,4) and (0,4)

Now f(x) is a contstant, it has no slope and is equal to 4, always.

Since g(x) cuts f(x) in point (-4,4), you can say that f(-4)= g(-4)

Second cut is in point (0,4), this means f(0)= g(0)

The correct option is number 2 f(-4)= g(-4) and f(0)= g(0)

Step-by-step explanation:

Ella has two 8 feet long boards, so in total, she has 16 feet of the boards.

Convert these 16 feet to inches. There are 12 inches in a foot, so multiply 16 by 12:

16(12)

= 192

So, there are 192 inches in the boards. Divide this by 15 to see how many 15 inch pieces she can cut:

192/15

= 12.8

We can only have a whole number answer, because the boards need to be a full 15 inches. So, round this down:

= 12

Ella can cut twelve 15 inch pieces.

The most likely mean for the sample distribution is option c. negatively skewed.

Based on the given information, we know that the mean (M) is less than both the median and the mode. This suggests that the distribution is skewed to the left (negatively skewed), with a long tail on the left side of the distribution.

The mean of a sample distribution is the average value of all the observations or measurements in the sample. It is calculated by adding up all the values in the sample and dividing the sum by the total number of observations in the sample.

A rectangle that is not a square has two pairs of sides of different lengths.

When it is rotated counterclockwise about its center, the longer sides will eventually become the shorter sides, and vice versa.

The minimum positive number of degrees it must be rotated until it coincides with its original figure is 180 degrees.

This is because after a rotation of 180 degrees, the longer sides will become the shorter sides and vice versa, and the rectangle will be in the exact same position and orientation as it was originally.

Any rotation less than 180 degrees will result in a mirror image of the original rectangle.

A major disadvantage of electron microscopes compared to light microscopes is that they cannot be used to view live specimens. Therefore, option B is the correct answer.

A major disadvantage of electron microscopes compared to light microscopes is that they cannot be used to view live specimens. This is because the electron microscope requires a vacuum environment to function properly, which would kill any live specimen. Additionally, electron microscopes can only see surface details and do not have a very high power of resolution. Lastly, electron microscopes can only be used by doctors or trained technicians, so they are not as widely available as light microscopes.

Therefore, option B is the correct answer.

Answer:

If you study for 2 hours, with 20-25 minutes of studying and a 5-minute break, you will study for approximately 80-100 minutes. This is because in one hour, there are three sets of 20-25 minutes of studying and two sets of 5-minute breaks. Therefore, in two hours, there will be six sets of 20-25 minutes of studying and four sets of 5-minute breaks. Thus, the total time spent on breaks would be around 20 minutes (4 x 5), leaving approximately 80-100 minutes for studying.
