Write and equation in standard form for a line that is (a) parallel (b) perpendicular to the line with an equation of y= 3x - 5 that passes through the point (5,8)
Answers
Answer:
(a) 3x -y = 7
(b) x +3y = 29
Step-by-step explanation:
(a) The standard form of the given line is ...
3x -y = 5
The parallel line will have a constant on the right that makes it go through (5, 8), so it will be ...
3x -y = 3(5) -(8)
3x -y = 7
__
(b) The perpendicular line will have coefficients for x and y swapped and one of them negated. Again, the constant is chosen to make it go through (5, 8).
x + 3y = (5) +3(8)
x + 3y = 29

Answer:
The number of students who actually went for the skiing is 0.75 times the total number of students .
Step-by-step explanation:
Given as :
Students were surveyed about their wither break plans
The percentage of students who did not go for skiing = 25 %
So, The percentage of students who did not go for skiing =100 % - 25 % = 75%
Let The total number of students = x
So, The number of students actually went for the skiing = 75% of the total number of students
I.e The number of students actually went for the skiing = × x
Or, The number of students actually went for the skiing = 0.75× x
∴ The number of students actually went for the skiing = 0.75 x
Hence The number of students who actually went for the skiing is 0.75 times the total number of students . Answer

Answer:
276°
Step-by-step explanation:
In the figure attached, circle D is shown.
arc BA + arc AC + arc CB = 360°
(7n + 12) + (13n - 16) + 6n = 360
26n - 4 = 360
n = (360 + 4)/26 = 14°
arc BAC = arc BA + arc AC
arc BAC = (7n + 12) + (13n - 16)
arc BAC = 20n - 4
arc BAC = 20(14) - 4 = 276°
Answer:
The answer is 276 degrees. I checked on Khan Academy. The reason 84 degrees is NOT the answer is because that would be the minor arc, not the major arc.

Answer: (a) 0.87x
(b) 0.87x = 174
(c) 200 players
Step-by-step explanation:
Let x be the total number of players who signed up for the season,
since 13% dropped , it implies that 13% of x dropped out , which means 0.13x dropped out.
To know the players who finished the league , it implies
x - 0.13x = 0.87x
This means that 0.87x finished the league
(a) The expression for the number of players who finished the season will therefore be 0.87x , this is as a result of subtracting those that dropped out (0.13x) from those that signed up ( x)
(b) The equation to represent the number of players who signed up for the soccer will thus be:
x - 0.13x = 174 , since it was given that 174 finished the league, this implies
0.87x = 174
(c) Solving the equation, we have
0.87x = 174
0,87x / 0.87 = 174 / 0.87
x = 200
Therefore 200 players signed up for the league
Step-by-step explanation:
a. 87% finished the season because 13% dropped
b. 100×174 = 87x
c. 17400 = 87x ➡ x = 17400 ÷ 87 ➡ x = 200 player signed up for the soccer league.
