Answer: y = -2x + 10
Step-by-step explanation:
Two lines are said to be perpendicular if the product of their slope = -1, that is , if 
is the slope of the first line and 
is the slope of the second line , if the two lines are perpendicular , then = -1
The equation of the line given :
y = 1/2x - 1
comparing with the equation of line in slope intercept form
y = mx + c , where m is the slope and c is the y - intercept , it implies that
= 1/2
Therefore :
= -2
To find the equation of the line with slope -2 and passes through the point ( 3 , 4 ) we will use the formula
= m (
)
y - 4 = -2 ( x - 3 )
y - 4 = -2x + 6
y = -2x + 6 + 4
y = -2x + 10
You do 9+3 which equals 12 then you multiply that by 4
Answer:
= 8n^2 +26n +6
Step-by-step explanation:
(4n+1)(2n+6)
= 8n^2 + 24n +2n +6
= 8n^2 +26n +6
Answer:
The percentage (V/V) of liquid menthol in the ointment is 1.59%.
Step-by-step explanation:
Given : A prescription for an ointment has 3.5 mL of liquid menthol in a total of 220 mL.
To find : Calculate the percentage (V/V) of liquid menthol in the ointment ?
Solution :
Volume of liquid menthol is 
Total volume of ointment is 
The V/V percentage is given by,
Therefore, the percentage (V/V) of liquid menthol in the ointment is 1.59%.
Answer:
Let x = the numerator
Let x + 3 = the denominator
(x + 5)/(x + 8) = 4/5 Cross multiply
5x + 25 = 4x + 32
x = 7
x + 3 = 10
7/10
