Iliana’s math grade increased from 65 to 86. Fiona’s math grade increased from 70 to 80. What is the difference, rounded to the nearest whole number, between the approximate percent increases?

Answers

Iliana's math grade increased by 21 which is 32.31%. Fiona's math grade increased by 10 which is 14.29%. To obtain the difference between the percent increases, subtract 14.29 from 32.31. Thus, the difference in percent increases of their math grades is approximately 18%.

Answer:

18%

Enter in standard form the equation of the line passing through the given point and having the given slope.. . B(2, - 5), m = -2/3

Answers

y = mx + b
slope(m) = -2/3
(2,-5)...x = 2 and y = -5
now we sub, we r looking for b, the y int
-5 = -2/3(2) + b
-5 = - 4/3 + b
-5 + 4/3 = b
- 15/3 + 4/3 = b
- 11/3 = b

equation is : y = -2/3x - 11/3...but we need it in standard form
Ax + By = C

y = -2/3x - 11/3
2/3x + y = - 11/3....multiply by 3
2x + 3y = -11 <== standard form

Answer:

y = mx + b

slope(m) = -2/3

(2,-5)...x = 2 and y = -5

now we sub, we r looking for b, the y int

-5 = -2/3(2) + b

-5 = - 4/3 + b

-5 + 4/3 = b

- 15/3 + 4/3 = b

- 11/3 = b

equation is : y = -2/3x - 11/3...but we need it in standard form

Ax + By = C

y = -2/3x - 11/3

2/3x + y = - 11/3....multiply by 3

2x + 3y = -11 <== standard form

Repeat Question 2 and Question 3 for corresponding points B and BGH, C and CGH, and D and DGH. With your measurements displayed in GeoGebra, move the line of reflection, , around the coordinate plane. Also, move the points of the preimage ABCD as you’d like. Based on your investigation, what can you conclude about the line of reflection with respect to the image and the preimage? Express your answer in geometric terms.

Answers

Answer:

A vertex on polygon ABCD and its corresponding vertex on polygon AGHBGHCGHDGH are always equidistant from the line of reflection. Each of the four line segments (, for example) is perpendicular to and cut in half by the line of reflection, . This means that is a perpendicular bisector of those line segments.
