Answer:
y = -1/2x -3
Step-by-step explanation:
The line perpendicular to one with a slope of 2 will have a slope that is the negative reciprocal of 2, that is, -1/2. The given point is the y-intercept of the required line, so we can write its equation directly in slope-intercept form:
y = mx + b
where m is the slope (-1/2), and b is the y-intercept (-3). Your line is ...
y = -1/2x -3
Firstly, add 2 to both sides of the equation: 
Next, multiply both sides by 5/3: 
Next, square root both sides: 
Lastly, factor out i (i = √-1) and <u>your answer will be
</u>
Y= 3 -x (1)
3x + 4y = 1 (2)
Substitute (1) for y in (2)
3x + 4(3 - x) = 1
Expand, simplify and then solve for x
3x + 12 - 4x = 1
3x - 4x = 1 -12
-x = -11
x = 11
Answer:
425 milliliters of compound A are needed
Step-by-step explanation:
We were told that
milliliters of compound A and
milliliters of compound B is needed to make the drug.
This means that each drug contains 11 milliliters of both compounds.
milliliters is the volume of each drug.
Therefore the chemist needed
millilirteres of compound A.
As you can see, the only point that lies on the line y+3=(2(x-1) is
A. (1,-3)
