The formula for density is
Givens
V = 163.5 mL
d = 0.492 grams / mL
Solution
m = d * V The formula has been rearranged.
m = 0.492 * 163.5
m = 80.442 grams.
<<<<< Answer
First,multiply the -2 by everything in the brackets
so that's, -6x-(b-4x)+(x+6b)
then combine like terms
that's -6x-(7b-3x) which is
-3x-7b I believe
Plot 7 on the y axis then go down 4 places and left 1 and keep repeating till u can’t plot any more then go back to the 7 on the y axis and go up 4 and right 1 unroll you can’t plot any more. Your line should be going down from left to right
Answer:
y = -0.25x + 2.25
Step-by-step explanation:
First, you can simplify the equation of the line it's perpendicular to (2y = 8x - 6) by dividing both sides by 2. This means you would get y = 4x - 3. From that you can conclude that the slope of that line is 4.
Lines always have a slope that is the negative reciprocal of the slope of the line they are perpendicular to, so you know the slope of the line is going to be -1/4.
So far, you have the equation y = -1/4x + b and you have to find b.
You can substitute in the point (-3, 3) so you would have 3= -1/4 * -3 + b
Solving,
3 = 3/4 + b
b = 2 and 1/4
Therefore the equation is y = -1/4x + 2 1/4 or y = -0.25x + 2.25
