PLEASE HELP ASAP Segment AB has point A located at (5, 4). If the distance from A to B is 7 units, which of the following could be used to calculate the coordinates for point B? (5 points)
a- 7 = square root of the quantity of x plus 4 all squared plus y plus 5 all squared
b- 7 = square root of the quantity of x plus 5 all squared plus y plus 4 all squared
c- 7 = square root of the quantity of x minus 4 all squared plus y minus 5 all squared
d- 7 = square root of the quantity of x minus 5 all squared plus y minus 4 all squared

(-2, 4)

Step-by-step explanation: The right coordinate for point B with 7 units as distance is (-2,4). To arrive at the answer, the distance formula is used. The solution for the problem is:

7= √[(-2-5)² + (4-4)²)

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
