Step-by-step explanation:

a) The inequality showing the number of push-ups Jada needs to do each day for the rest of the week to meet her goal of 100 push-ups for the week is 30 + 6x ≥ 100.

b) The solution to the inequality shows D. Jada needs to do at least 12 push-ups each day for the rest of the week to meet her goal

Inequality is a mathematical statement that two or more mathematical expressions are unequal and not equivalent.

Inequalities are depicted in the following ways:

The total number of full push-ups for the week = 100

The number of push-ups done on Sunday = 30

The remaining number of push-ups for 6 days = 70 (100 - 30)

30 + 6x ≥ 100

6x ≥ 70

x ≥ 12

The answer to the system of equations 3x-2y=3 and -4x+5y=-11 is (6, 7). An equation is a proposition that has two equal sides as well as an equal sign .

what is equation ?

It is thought that a number's simplest form is represented by its smallest equivalent fraction. finding the simplest form: what to do. For shared factors, look into the numerator and denominator. Examine a fractional integer to determine if it is a prime number. An equation is a proposition that has two equal sides as well as an equal sign in the middle. In the general form of any equation, the degrees of all the variables are listed in descending order. The common representation of a system of equations is an x + b = 0. x + b y + c = 0 is the general form of a two-variable linear equation (or something similar). Identity or conditional equations are the two categories under which equations fall. An identity holds true regardless of how the variables are valued.

given

Equation substitution is another name for combining the equations. When one variable is added to another equation, this is done.

-8x - 5y = -13

-4x - 5y = 11

Let's make the second equation a one-variable-on-each-side equation.

-5y = 4x + 11

y = -4/5x - 11/5

Put this into your first equation right now.

-8x - 5(-4/5x - 11/5) = -13

Give out the -5 symbol.

-8x + 4x + 11 = -13

Stack similar phrases.

-4x + 11 = -13

-4x = -24

Divide both sides by -4 to isolate x.

x = -24/-4

x = 6

Reintroduce this to either equation now.

y = -4/5(6) - 11/5

Multiply.

y = -24/5 - 11/5

Subtract.

y = -35/5

Simplify.

y = -7

Answer:

48 sq cm

Step-by-step explanation:

The smaller square is 3' x 3' = 9 square feet.

The larger square is 9' x 9' = 81 square feet.

9 goes into 81 exactly 9 times (81 / 9 = 9), so we could just multiply the 54 cm by 9 and get your answer in centimetres.

Answer: 5

Step-by-step explanation: To solve f(x), g(x), or f(g(x)) problems, we place the value of x in the functions with the value that we are given. This value will be f(g(5)) or g(3) or f(27). We plug in the number in the parentheses.

In this problem, we have to first plugin 5 to g(x) then plug g(5) into f(x).

First, we do g(5)=sqrt((5^2)+2). This gives us 3. Then we plug in 3 which is g(5) into f(x). This gives us f(g(5)) or f(3)=sqrt((3^3)-2) which is 5.

Answer: a. To find the age of a shark that is 200 centimeters long, we can set the function equal to 200 and solve for t:

L = 266 - 219e^(-0.05t)

200 = 266 - 219e^(-0.05t)

Solving this equation for t, we get t ≈ 2.11 years.

b. To find the length of a shark that is twice as old as the shark in part (a), we can substitute 2.11*2= 4.22 for t into the function:

L = 266 - 219e^(-0.05(4.22))

This will give us the length of the shark that is twice as old as the shark in part (a) in centimeters.

Proportionately, the number of cups of strawberries that Maria needs to use is 3¹/₈ cups.

Proportion refers to a part of a whole.

Proportion is a ratio of one value to another.

Proportions are depicted as decimals, fractions, or percentages.

Thus, we can multiply the fraction of strawberries against the combined value of the other fruits to determine the number of cups of strawberries needed.

Kind of Fruit       Amount

Grapes               3²/₃ cups

Melon                 2¹/₄ cups

Pineapple          2³/₄ cups

a. The function, (f + g)(x), is evaluated as: (f + g)(x) = 5x + 11

b. The function (f + g)(5) = 36

c. (f + g)(5) = 36 means in 5 months, the total number of animals adopted at the two shelters is 36.

We can evaluate functions just as we solve normal algebraic equations when we plug in the given value of a variable.

Given the following:

f(x) = 4x + 9 [number of animals at one shelter]

g(x) = x + 2 [number of animals at another shelter

Part A: Find (f + g)(x)

(f + g)(x) = f(x) + g(x) = 4x + 9 + x + 2

Combine like terms:

(f + g)(x) = 5x + 11

Part B: Find (f + g)(5)

Substitute the x = 5 into the function (f + g)(x)

(f + g)(5) = 5(5) + 11

(f + g)(5) = 25 + 11

(f + g)(5) = 36

If the two graphs are mirror images of one another across the line y = x, then they are inverse functions.[tex]$f(x)=\frac{x}{3}+10$ \\[/tex] and [tex]$g(x)=3 x-10$[/tex]

As for looking at the graphs, we already knew that. You should keep in mind that inverse functions are represented by two graphs that are mirror images of one another over the line y = x. The broadest definition of an inverse function is one that "reverses" another function.

The inverse, for instance, must take b to an if a function goes from a to b. When the first and second elements of each pair in the original function are switched, a set of ordered pairs is obtained that is known as the inverse of the function. The act of switching the x and y coordinates is known as obtaining an inverse. They aren't opposites. The output of the first function is sent through an inverse function, which then generates an output whose input was the first function.

Answer:

Step-by-step explanation:

To find the percentage of men who are over 70.5 inches tall, we need to use the standard normal distribution table, which gives the proportion of observations that fall within a given range of standard deviation from the mean.

We first need to standardize the height of 70.5 inches by subtracting the mean (68 inches) and dividing by the standard deviation (2.5 inches) to get (70.5 - 68) / 2.5 = 0.8

This tells us that 70.5 inches is 0.8 standard deviations above the mean.

We can then look up the proportion of observations that fall within this range in the standard normal distribution table, which is approximately 0.1587 or 15.87%. So, the answer is (1-0.1587) = 84.13 or 84.13%.
