Answer:
A
Step-by-step explanation:
Because 45 + 2x = 180 divide it by 2 gives 4
The slope of the first equation has a slope of one and a y intercept of -4. The second equation has a y intercept of -2.3333 as seen when plugging in 0 for x, so the same y-intercept and same line are out of the question. This means either they have the same slope and thus are parallel or intersect at some point. A simple way to find out? Plug in 1 for x on the second. If it isn't -1.33333, which is a slope of positive 1 such as in the first equation, they WILL INTERSECT somewhere. When plugging in 1, we get
3y - 1 = -7
3y = -6
y = -2
(1, -2) is the next point after (0, -2.3333)
That means it is most certainly not the same slope, and thus they will intersect at some point. The two slopes are 1/1 and 1/3 if you weren't aware.
Hey there :)

Step-by-step explanation:
There are 0.001 grams in a milligram. (1,000 milligrams in a gram.)
The total dose should be 0.2 grams.
Hope this helps.
To find the perpendicular line, we need to find the negative inverse slope.
y = -1/2x - 2
This line also passes through the point since both have the y intercept / value of -2.
Hope this helps!
