Plug in 0 for x. Plug in 0 for y.
X pounds of $3
y pounds of $3.25
x+y = 200
300x + 325y = 320*200
300x + 325y = 64000
x+y =200
300x +325y =64000
Solve by eliminating
Multiply top one w/-300
-300y =60000
325y=64000
25y = 4000
y= 160 then
x + 160= 200
x = 40
So the mixture has;
40 pounds of $3 coffee
160 pounds of $3.25 coffee
Answer:
Number line C
Step-by-step explanation:
First, you isolate x. This gives you x>=3+4 or x>= 7. Next, you find a number line greater than or equal to which cancels out A and D. Now whichever line starts on 7, is the answer which is C
The point of intersection of these two lines is (2, 1)
The equation of a horizontal line that passes through the point (1, 1) is:
y = 1
The equation of a vertical line that passes through the point (2, 2) is:
x = 2
The point of intersection would be at:
x = 2, y = 1
The point of intersection of these two lines is (2, 1)
