An equation that has two variables which the formula Ax + By = C.

An equation is said to be linear if the maximum power of the variable is consistently 1. Another name for it is a one-degree equation. A linear equation with one variable has the conventional form Ax + B = 0. In this case, the variables x and A are variables, while B is a constant. A linear equation with two variables has the conventional form Ax + By = C. Here, the variables x and y, the coefficients A and B, and the constant C are all present.

A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1.

So, an equation that has two variables which the formula Ax + By = C.

The future value of $2000 at a 3% interest rate compounded annually for 3 years would be $2185.40.

The future value of $2000 at a 3% interest rate compounded annually for 3 years can be calculated using the formula:

FV = PV * (1 + r)ⁿ

where PV is the present value, r is the annual interest rate, and n is the number of compounding periods.

In this case:

FV = $2000 * (1 + 0.03)³

FV = $2000 * 1.03³

FV = $2000 * 1.0927

FV = $2185.40

Answer:

y = 10x + 20.

Step-by-step explanation:

Slope of the line = (60-30) / (4 - 1)

                            = 30/3

                            = 10

y-intercept = 20

Formula is y = mx + c where m = slope and c = y-intercept

So, the answer is y = 10x + 20.

Answer:

27 minutes

Step-by-step explanation:

Convert 45% to a fraction

1 hour = 60 minutes

45% of 1 hour = 9/20 x 60 = 27 minutes

If the variance is unknown and the sample size is small, then the t-test statistic is appropriate to use.

The t-test is a statistical hypothesis test used to identify whether an unknown population mean is different from a particular value. A t-test is appropriate to use when there is a small random sample collected from some statistical population and the sample is required to be compared with the mean from the sample to another value. Also, the variance of the sample is not known.

Thus, a t-test is appropriate to be used when the population variance or standard deviation is not known, and a sample size is less than 30.

The equation pair cannot be solved if the lines are parallel.

Although a system of linear equations typically has a single solution, it occasionally may have infinite or no solutions (parallel lines) (same line). When the graphs cross at a particular point, a system of linear equations has a single solution.

When the graphs are parallel, an equation system with linear components cannot be solved. The graphs of a system of linear equations have an infinite number of solutions.

Complete Question:

What is the degree of the polynomial 2x² 5x³ 7?

The angle 67.5 degrees is 3 times its complement

Let us assume that the complement of the angle be p degrees.

Given that the measure of the angle is three times its complement.

So, the measure of the angle = 3p

We know that two angles are complementary when their measures add to 90 degrees.

The sum of complementary angles is 90 degrees.

So we get an equation, p + 3p = 90

We solve this equation to find the value of p.

p + 3p = 90

4p = 90

p = 90/4

p = 22.5 degrees

so, the measure of complement of the angle is 22.5 degrees.

And the required angle would be, 3 × 22.5 = 67.5 degrees

All possible solutions for the inequalities are from 2.5 to infinity.

Option F is the correct answer.

All possible solutions for the problem situation are 2.5 to 8.

Option D is the correct answer.

It shows a relationship between two numbers or two expressions.

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal = ≤

Greater than and equal = ≥

We have,

27 ≤ 12 + 6x

Solve for x.

27 - 12 ≤ 6x

15 ≤ 6x

x ≥ 15/6

x ≥ 5/2

x ≥ 2.5

This means,

x values can be 2.5 and more.

Now,
For x = 8,

12 + 6 x 8

= 12 + 48

= 60 gallons (possible)

For x = 9,

12 + 6 x 9

The equation in slope-intercept form as y = 2x - 4, where 2 is the slope and -4 is the y-intercept.

The equation y = 2x - 4 can be written in slope-intercept form as y = 2x + b, where b is the y-intercept. To find the slope and y-intercept of the equation, we need to solve for b.

The y-intercept is the point where the line crosses the y-axis. To find the y-intercept, we can set x equal to 0 in the equation to get y = 2(0) - 4. This simplifies to y = -4, so the y-intercept is -4.

The slope is the rate at which the line rises. To find the slope, we can take the coefficient of x, which is 2. So the slope of the equation y = 2x - 4 is 2.

In summary, the slope of the equation y = 2x - 4 is 2 and the y-intercept is -4. We can write the equation in slope-intercept form as y = 2x - 4, where 2 is the slope and -4 is the y-intercept.
