What error did she make? She simplified the denominator incorrectly. The denominator simplifies to –7. She labeled the points incorrectly. The point (–7, 4) should be (x1, y1). She used an incorrect formula. The formula should be the change in y-values with respect to the change in the x-values. She used an incorrect formula. The formula should be the sum of the x-values with respect to the sum of the y-values.

Answers

By what the question asks, I assume that this refers to getting the slope in a linear equation.

The correct option is:

She used an incorrect formula. The formula should be the change in y-values with respect to the change in the x-values.

A general linear equation is given by:

y = a*x + b

where a is the slope and b is the y-intercept.

We know that for a line that passes through points (x₁, y₁) and (x₂, y₂) then the slope can be computed as:

a = (y_2 - y_1)/(x_2 - x_1)

Notice that the formula is the change in y-values with respect to the x-values,

So we can conclude that the correct option is:

"She used an incorrect formula. The formula should be the change in y-values with respect to the change in the x-values."

Answer:

The formula should be the change in y-values with respect to the change in the x-values. She used an incorrect formula

Step-by-step explanation:

The question is incomplete. Here is the complete question.

Anya found the slope of the line that passes through the points (–7, 4) and (2, –3). Her work is shown below. Let (x2, y2) be (–7, 4) and (x1, y1) be (2, –3). m = = = The slope is . What error did she make? She simplified the denominator incorrectly. The denominator simplifies to –7. She labeled the points incorrectly. The point (–7, 4) should be (x1, y1). She used an incorrect formula. The formula should be the change in y-values with respect to the change in the x-values. She used an incorrect formula. The formula should be the sum of the x-values with respect to the sum of the y-values.

Slope of a line is expressed according to the formula;

Slope m = Δy/Δx

Slope = y2-y1/x2-x1

Given the coordinates (–7, 4) and (2, –3), from the coordinates;

x1 = -7, y1 = 4, x2 = 3, y2 = -3

Substitute into the formula;

Slope = -3-4/3-(-7)

Slope = -7/3+7

Slope = -7/10

Based on Anya workings, it can be concluded that Anya used an incorrect formula. The formula should be the change in y-values with respect to the change in the x-values

The total rainfall in Forks, Washington, this October was 8 3/8 in. In September, 60% less rain fell than in October.How much rain fell in September in Forks, Washington?

Express your answer as a mixed number in simplest form.

Answers

Given:
October: 8 3/8 inches
September : 60% less rain fell than in October.

This means that only 40% rain fell in September based on the amount of rain that fell in October.

8 3/8 ⇒ (8*8)+3/8 = 67/8
40% is 4/10

67/8 * 4/10 = 268/80 = 3 28/80 or 3 7/20 or 3.35

28 ÷ 2 = 14
80 ÷ 2 = 40
14 ÷ 2 =   7
40 ÷ 2 = 20

In September 3 7/20 inches or 3.35 inches of rain fell.
If you would like to know how much rain fell in September, you can calculate this using the following steps:

60% of 8 3/8 in. = 60% * 8 3/8 = 60/100 * 67/8 = 201/40 = 5 1/40 in.

8 3/8 - 5 1/40 = 67/8 - 201/40 = 67/20 = 3 7/20 in.

The correct result would be 3 7/20 in.

Dustin says that FGH is an equilateral triangle because the sides appear to be the same length.Is his reasoning valid?Explain

Answers

His reasoning is not valid because they might actually appear to be equal to his sight, but should he measure them they might not exactly be.

So he just can't look at it and conclude. He can say it is equilateral if each angles measures 60 degrees.

Answer:

Whatis(2+0.4+0.6)

First we have to arrange the numbers in sequence...

2.0 \: + \: 0.4 \: + 0.6 \n 3.0 \: or \: 3

Here I have taken this 0 after the point ..as the rest of the digit are in tenths place or after the point...

The answer is 3.

We will not calculate the 0 as it does not have any value.

Ans) 3
