Answer:
Step-by-step explanation:
it is maximum.
when leading coefficient of x² is negative,
It is downward parabola.
or
y=-2x²+10x+1
=-2(x²-5x+(-5/2)²-(-5/2)²)+1
=-2(x-5/2)²+2×25/4+1
=-2(x-5/2)²+25/2+1
=-2(x-5/2)²+27/2
maximum value of y is 27/2 and is attained at x=5/2
vertex is (5/2,27/2)
Step 1 : Divide the numerator by the denominator.
Step 2 : Write the quotient in the front as a whole, remainder in the numerator part and divisor as the denominator.
Therefor you'll have 7 1/7 as a mixed number.
1.5x+4y=16
5x+4(-16)=16
5x-64=16
5x=80
x=16
2.3x+6y=15
-2x+3y=-3
Multiply the 2nd equation by 2
3x+6y=15
-4x+6y=-6
7x=9
x=9/7
3x+6y=15
3(9/7)+6y=15
27/7+6y=15
6y=78/7
y=78/42 or 39/21 or 13/7
3.7y = -14x + 42
<span>7y = 14 x + 14
-14x+42=14x+14
-28x=-28
x=1</span>
