Answer:
y = - 6x - 2
Step-by-step explanation:
The straight line equation is y = mx + c
First step is to bring the equation given to this form, where you make y the subject.
Now you can easily note down the gradient(m1). You will need it to find the gradient(m2) of the perpendicular line, because m1 × m2 = -1
After you have that substitute the value and the values of x and y given to find c .
Lastly, substitute the value of m2 and c into y = mx + c to find the line that is perpendicular .

Answer:
It would get <u>20</u> complete turns.
Step-by-step explanation:
Given:
The lead of a screw is the distance that the screw advances in a straight line when the screw is turned 1 complete turn. If a screw is 2 1/2 inches long and has a lead of 1/8 inch,
Now, to find complete turns.
Length of screw = 
Lead of screw = 
As, given the screw advances in a straight line when the screw is turned 1 complete turn.
Now, to get the number of complete turns it would divide length of screw by lead of screw:
Therefore, it would get 20 complete turns.
12/ sin(113.17) = b/ sin (37.81)
so b= 8
7.5% of 20......turn ur percent to a decimal by dividing it by 100...
7.5 / 100 = 0.075..." of " means multiply....0.075(20) = 1.5 <=
b*h=area
3*2=6
8*7=56
56+6=62
They will need 62 tissues
Hope this helped :)
