We can already eliminate B and D since y is greater than everything else in this inequality. The -2 in the equation is where the y-intercept is, and the origin is when a line hits 0,0 on the grid. Knowing that, what would be your answer?

How would I exactly resolve this ​
Lilit [14]

Answer:

m∠BFE = m∠BAF + m∠AFE

m∠BFE = 65º + 25º

m∠BFE = 90º

m∠AFC = m∠AFB + m∠BFC

m∠AFC = 65º + 45º

m∠AFC = 110º

m∠BFD = m∠BFC + m∠CFD

m∠BFD = 45º + 70º

m∠BFD = 115º

Sergio [31]

Answer:

D. 4(2x² + 4x - 6); 130.0 inches

Step-by-step explanation:

Margot is sewing a ribbon on a seam along the perimeter of a square pillow. The side length of the pillow is 2x²+1 inches. She plans to make a similar pillow, including the ribbon, whose side length is 4x−7 inches. What expression can be used for the length of ribbon that she needs for both pillows, and what is the length if x = 3.5?

2x2+4x−6; 22.0 inches

2x2+4x−6; 32.5 inches

4(2x2+4x−6;) 88.0 inches

4(2x2+4x−6;) 130.0 inches

Perimeter of a square = 4 * side length

1- First square pillow

length = 2x²+1 in

Perimeter of first pillow = 4 * (2x²+1) in

Second square pillow

length = 4x-7 in

Perimeter of second pillow = 4(4x-7) in

Total ribbon length required = perimeter of first square pillow + perimeter of second square pillow

Total ribbon length required = 4(2x²+1) + 4(4x-7)

Factorise

4 is the common factor

=4(2x²+1)+(4x-7)

=4(2x²+1+4x-7)

=4(2x²+4x-6)

Total ribbon length required=4(2x²+4x-6)

If x=3.5

Total ribbon length required=4(2x²+4x-6)

=4{2(3.5)²+4(3.5)-6}

=4{2(12.25)+14-6)

=4(24.5+14-6)

=4(32.5)

=130.0 inches

In one statistics course, students reported studying an average (mean) of 9.92 hours a week, with a standard deviation of 4.54.
quester [9]

Answer:

For the student who is studying 10 hours a week is in the 57.93th percentile.

Step-by-step explanation:

Corresponding z-score for the student who studies 10 hours a week can be calculated by the formula

z=\frac{x-M}{s} where

  • x is the hours student work in a week, which is 10,
  • M is the mean studying hour of the class, which is 9.92,
  • s is the standart deviation which is 4.54

from here we find that z=\frac{10-9.92}{4.54}≈0.2

Corresponding percentile for z=0.2 is 57.93

<h3>What is a line graph?</h3>

A line graph is a graph that is used to represent numerical data. It shows the changes in the data with the passage of time. There are two axes on a line graph, the vertical axis and the horizontal axis. The range of the vertical axis should start from 0 and end at the largest number of data set.
