Can someone show how to do this step by step with a graph?

The given equation y = -3x + 5 has infinitely many solutions.

We have linear equation y = -3x + 5

We need to encounter how many solutions can satisfy the given equation. 

We know that,

y = -3x + 5 is a linear equation in two variables in the form ax + by + c = 0

For x = 0, y = 0 + 5 = 5. Therefore, (0, 5) is one solution.

For x = 1, y = -3 × 1 + 5 = 2. Therefore, (1, 2) is another solution.

For y = 0, -3x + 5 = 0, x = 5/3. Therefore, (5/3, 0) is another solution.

Clearly, for different values of x, we get different values for y. Thus, any value substituted in the place of x in the given equation will form another solution for the given equation. So, there is no limitation to the number of different solutions obtained by substituting real values for x in the given linear equation. Thus, a linear equation in two variables can have infinitely many solutions.

Thus, y = -3x + 5 has infinitely many solutions.

The graph that depicts a function is graph when the vertical line test is used (b).

By visually counting the number of times the curve crosses vertical lines, the vertical line test is a graphical approach for verifying whether a curve in the plane accurately depicts the graph of a function. the graph of a function can only be intersected by any vertical line in the plane once as a result.

A graph must satisfy the vertical line test in order to be considered a function representation. The vertical line test requires that the line from the x-axis only once crosses an associated y-value.

Graphs (a), (c), and (e) fail the vertical line test, indicating that they do not reflect a function.

So, graph is the name of the graph that represents a function (b)

The solution to log base 7 of 1 is x=0, which is the value of the power to which 7 must be raised to get the value 1.

The logarithm function is an inverse function of the exponential function, and it is defined as log_b(x) = y means b^y = x. In other words, it represents the power to which the base b must be raised to get the value x.

In this case, we are solving log_7(1), which means we are looking for the power to which 7 must be raised to get the value 1.

Since any number raised to the power of 0 is 1, we can say that 7^0 = 1, which means that log_7(1) = 0.

To solve log base 7 1, you need to find the value of x that satisfies the equation log_7(x) = 1.

Using the definition of logarithm, log_b(x) = y means b^y = x.

So to solve log7(1), we can set 1 = 7^x and get x = log7(1) = 0

So the solution to log base 7 of 1 is x=0.

Possible way in which two consecutive odd numbers are added to sum of 2023 is by evaluation using the formula (2n - 1) + (2n + 1) = 2023, so that we have 1010.5 + 1012.5 = 2023

Consecutive odd numbers are a sequence of numbers that are separated by a difference of 2 and are all odd numbers. For example the first four odd numbers are: 1, 3, 5, and 7. Odd numbers can be generated using the formula 2n -1.

We shall represent the first odd number with (2n - 1) so that the two consecutive odd numbers will be expressed as:

(2n - 1) + (2n + 1) = 2023

2n + 2n = 2023

4n = 2023

n = 2023/4 {divide through by 4}

n = 505.75

Therefore the two consecutive odd numbers added to sum of 2023 are derived as:

2(505.75) - 1 = 1010.5 and 2(505.75) + 1 = 1012.5

Answer: Well, let’s consider a number, [math]n[/math], it could be even or odd, it doesn’t ...

Step-by-step explanation:

Complex fractions are called complex because they contain one or more fractions within the numerator and/or denominator of the fraction. These fractions within the fraction make the fraction more complex or difficult to simplify than a regular fraction, which only has a single numerator and denominator.

The term "complex" in mathematics often refers to something that is composed of multiple parts or layers, and that requires more steps or understanding to work with or solve.

In this case, the presence of one or more fractions within the fraction makes it more complex than a regular fraction, hence the name "complex fraction."

Another reason for the term complex is that the fractions in the numerator and denominator may have different or even the same variables, making it difficult to cancel them or simplify the expression.

On solving the exponential function A(t) = 80 (0.965)^t, the number of animals will drop to 15 after 47 years.

What is an exponential function?

The formula for an exponential function is f(x) = a^x, where x is a variable and a is a constant that serves as the function's base and must be bigger than 0.

The number of animals studied for the research = 80

The decrease rate of certain species = 3.5%

The rate of decay in exponential term = (1 - 0.035) = 0.965

The exponential function for the situation is -

A(t) = 80 (0.965)^t

Where, t is the number of time periods in years and A(t) = change in the population of animals.

The number of animals drop to 15.

So, substitute the value of A(t) = 15 in the equation -

A(t) = 80 (0.965)^t

15 =  80 (0.965)^t

15/80 = 0.965^t

0.1875 = 0.965^t

ln(0.1875) = t ln(0.965)

t = ln(0.1875)/ln(0.965)

t = -1.6739/-0.0356

t = 47.01

Therefore, the time period value is obtained as t=41 years.

CI will yield more amount, because simple interest generates earnings from principal only.

Interest rate is the amount charged over and above the principal amount by the lender from the borrower.

Given that, A recent college graduate is looking to begin saving for retirement. Option A is a savings account with 3.5% annual simple interest. Option B is a savings account with 3.5% annual interest compounded monthly.

Let the principal amount be, $20000

Solving for simple interest, we get,

SI = PRT / 100

= 20000×3.5×10 / 100

= 7000

Therefore, amount = $27000

Now, CI =

A = P(1+r)ⁿ

A = 20000(1+0.035/12)¹²⁰

A = 1241286.32

The number of people in the group who claim to take one or more online courses is the random variable, or x. The probability distribution is given by the values of x and the probabilities associated with them (P(x)). From the given values, we can calculate the mean and standard deviation of the distribution. The mean of the distribution is 1.62, and the standard deviation is 0.84. This means that, on average, 1.62 students in the groups of three will say that they take one or more online courses.
