Answer:
Step-by-step explanation:
2x + 3y = -3 3x + 5y = -9
3y = -2x - 3 5y = -3x - 9
y = -2/3x - 1 y = -3/5x - 9/5
slope = -2/3 slope = -3/5
y int = -1 y int = -9/5
to find the answer, u must compare the slopes and the y intercepts.
if they have the same slope and different y int's, then there is no solution
if they have the same slope and the same y int's, they have infinite solutions
if they have different slopes and different y int's, they have 1 solution
so this system has 1 solution <===
B i am pretty sure
Post the part one of the problem please and thank you
your answer should be(B) from my point of view
as shown in image provided
have a gd day :)
the answer is 2 1/4 cups of oil
if he wants to triple the ingredient then you would triple the numerator and than simplify your new fraction
3 times 3 is 9 = 9/4
9 divided by 4 is 2.25 = 0.25 is equal to 1/4 so it would be 2 1/4 cups of oil
