14/15-5/12 = 31/60
31/60 = 0.5166...
Answer:
-2/3
Step-by-step explanation:
I took the whole numbers and multiplied them by 3 and added them to the numerators, so I did 5/3 - 7/3, which would be -2/3
Based on point P(0,16), we substitute in the parabola to find a.
16=a(0-3)^2-2 => a=(16+2)/9=2
so the parabola is
y=2(x-3)^2-2 ..........................(1)
Solve for zeroes of (1);
0=2(x-3)^2-2 => (x-3)^2=1 => x=2 or x=4
Now the line passes through (0,16), (4,0) => y,x intercepts are 16 & 4.
Using the symmetric form
x/4+y/16=1
4x+y=16 => y=16-4x
Answer:
Step-by-step explanation:
line that is parallel to x-axis the slope = 0
an equation is : y= ax+b a = 0
passes through the point (3,5) : y =5 when x = 3 so : b = 5
an equation is : y = 5
