PLEASE Find the equation of the line............................perpendicular to the line y= 5x -1 and passes through the points (10,8)

Answers

Answer 1

Answer: Since it's perpendicular to the line with the slope 5, you take the reciprocal of 5 which is 1/5 and change the sign: -1/5. So you have the equation: y=-(1/5)+b. To find b you substitute x and y for the coordinate (10,8).
y=(-1/5)x+b
8=(-1/5)10+b
8=(-10/5)+b
8=-2+b
+2 +2
10=b

So your new equation is: y=1x+10
5

A 5-column table with 4 rows. The columns are labeled sock 2 and the rows are labeled sock 1. Column 1 contains entries blank, b, b, w, w. Column 2 contains entries b, (b, b), (b, b), (w, b), (w, b). Column 3 contains entries b, (b, b), (b, b), (w, b), (w, b). Column 4 contains entries w, (b, w), (b, w), (w, w), (w, w). Column 5 contains entries w, (b, w), (b, w), (w, w), (w, w).A drawer contains one pair of brown socks and one pair of white socks. The table shows the possible outcomes, or sample space, for choosing a sock, replacing it, and then choosing another sock.

A concert charges $24.50 per daily adult ticket and $13.75 per child’s ticket. A group of 90 people paid $1560.00 for tickets. Write a system of equations that could be used to find x, the number of adult tickets purchased, and y, the number of children's tickets purchased?I know the answer i just need to know how to solve it. Thanks :)

Answers

x=adults
y=childern

x+y=90
24.50x+13.75y=1560

so
mutliply the first equation by -13.75 and add to second equaiton

-13.75x-13.75y=-1237.5
24.50x+13.75y=1560 +
10.75x+0y=323

10.75x=322.5
divide both sides by 10.75
x=30

x=30
sub back

x+y=90
30+y=90
minus 30 both sides
y=60

x=30
y=60
30 adults
60 kids
