The answer is 3.9 x 10^-5
Step-by-step explanation:
A. One book =$9.25÷b
=$9.25/b
B.One pen=$1.30÷p
=$1.30/p
C. One book+One book
=[($9.25÷b)+($1.30÷p)]÷($9.25+$1.30)
=[(&9.25/b)+($1.30/p)]/($10.55)
Answer: 2x + 5y = - 10, Cy + 4 = (x-5)
Dy - 4 = (x+ 5)
Step-by-step explanation:
Equation of the line
5x - 2y = -6
Conditions for perpendicularity
m1 x m2 = -1
To get m1, rearrange the equation
2y = 5x + 6
y = 5x/2 + 3
n1 = 5/2 and m2 = -2/5
To get C
y = mx +c
-4 = -2 x 5/5 + C
-4 = -2 + C
C = -4 + 2
C = -2
To get the equation of the second line
y = -2x/5 - 2
Multiply through by 5
5y = -2x - 10
2x + 5y = 10.
