Answer:
If you round it to nearest tenth it will be 50
Step-by-step explanation:
14x3.14=49
Step 1: 3x + 4y = 15
Step 2: Get in Slope intercept form = y=mx+b
Step 3: Subtract 3x from both sides since your trying to get Y alone
Step 4: 4y = -3x + 15
Step 5: Divide 4 from both sides since 4 cannot go into -3 or 15 leave it as is
Step 6: Y =

+

Step 7: Point slope form= y-y=m(x-x)
Step 8: (8, -2) are your points 8x and -2y
Step 9: Substitute
Step 10: y - 2 =

(x - 8)
Step 11: Distribute
Step 12: y - 2 =

+ -6
Step 13: Add 2 to both sides
Answer : y =

+ 4
