The slope of the line is 2 whose equation is given by y = 2x.

The given equation is y = 2x

The general equation of the line is given by

y = mx +c where m is the slope and c is the intercept of the line.

The slope of line a line's steepness can be determined by looking at its slope. The slope is calculated mathematically as "rise over run."

The intercept of the line is a point on the y-axis known as an intercept is where the line's slope passes.

On Comparing the given equation with the general equation, we have:

m = slope = 2

Thus the slope of the line is 2.

Elodia [21]

Answer:

Step-by-step explanation:

Apply the Pythagorean Theorem to determine whether or not the given triplets represent right triangles or not:

I. 5 feet and 13 feet: 5^2 + 12^2 = 13^2 is TRUE

II. 9 ft and √63 ft: 9^2, 63, 12^2: 63 + 81 do add up to 144 TRUE

III. 2, 10, 12^2: 2 + 10 do NOT add up to 144. FALSE

Which operation can be used with the augmented matrix below?

ycow [4]

Answer:

Multiply row 2 by-1 and add it to row 3.

Step-by-step explanation:

The given augmented matrix is $\left[\begin{array}{ccc}3&-21&15\\15&8&15\\-2&-1&3\end{array}\right]$

The permissible row operations are:

1. Switching rows

2. Multiplying a row by a nonzero constant.

3. Adding/Subtracting two rows

Therefore the correct option is: Multiply row 2 by-1 and add it to row 3.

1. Which function describes the sequence 2,4,6,8......? *

Lyrx [107]

Answer:

$f(1) = 2$

$f(n) = f(n-1) + 2$ where $n\geq 2$

Step-by-step explanation:

Given

2,4,6,8...

Required

Which function determines the sequence

Represent the terms with n where n is 1,2,3....

Analyzing each term:

$f(1) = 2$

$f(2)= 4 = 2 + 2 = f(1) +2$

$f(3)= 6 = 4 + 2 = f(2) +2$

$f(4)= 8 = 6 + 2 = f(3) +2$

Notice that each term is an addition of the previous term and 2

In other words:

$f(n) = f(n-1) + 2$

However, the function is only effective for values of n greater than or equal to 2

So: $n\geq 2$
