Answer:
these problems are always tough b/c they want you to translate normal thinking into math jargon :D soooo....
Step-by-step explanation:
they use the point slope formula... which looks like
y = = m(x - )
where ( , ) are the x , y coordinates of some point you're given.. sooo
they give us two points.. so we can put either one of those into the formula.. but we also have to find m.... or the slope ... to find m.. use the slope equation of
m = ( - ) / ( - )
call either point P1 and P2 ... i'll pick the top point as P1 and bottom as P2
then
m = ( -3 -1 ) / ( 1 - 3 )
m = -4 / -2
m = 2 ( yay :) )
now use either point and plug it into the point slope formula, i'll use P1
y - 1 = 2(x-3) ( this is the answer they are looking for )
Answer:
5 1/3 ounces
Step-by-step explanation:
1 pint is equal to 16 ounces.
The recipe asks for 1 pint of sour cream (16 ounces).
The chef needs to use only 1/3 as much as the recipe asks for.
Therefore, the amount of sour cream that the chef needs to use is:
1/3 * 16 = 5 1/3 ounces
The chef would use 5 1/3 ounces of sour cream.
Answer:
No Solution.
Given Equations:
- 3x + y = 15 ....[Equation 1]
- y = -3x + 8 ....[Equation 2]
Substitute Equation 2 into 1
No solution, as L.H.S ≠ R.H.S
