Answer:
3x +4y = -8
Step-by-step explanation:
The perpendicular line will have the x- and y-coefficients swapped, and one of them negated. The constant in the equation will be such that the given point values will satisfy the equation.
4x -3y = 18 . . . . . . given equation
3x +4y = 3(8) +4(-8) = -8 . . . . swap coefficients, used point coordinates
3x +4y = -8 . . . . . the equation of the line you want
Answer: multiply it by .1 or just move the decimal point once to the left ex :
10% of 40 is 4
Solution :
A). x = 2 (mod 3)
x = 3 (mod 5)
x = 4 (mod 7)
≡ 53(mod 105)
Hence the solution is 105 k + 53 > 1000 for k = 10
Therefore, the minimum number of students = 1103
B).
By Eulu's theory
if n and 935 are coprime.
Now, and 80 x 8 = 640
⇒ g(n,935) = 1
⇒ 5, 11, 17 do not divide n
The answer is D. 100%
Markup is the amount added to the total cost of product to cover the total overheads and profit.
In markup based on selling price method, the selling price is considered as the endpoint that companies wanted to achieve, (100%) and the markup will be adjusted to cater into thaat equation.
Sn = n/2 ( a1+an)
= 6/2 (10+85)
= 3 (95)
= 285
