Answer:
2 5/7
Step-by-step explanation:
Set up the division problem in long division format. Divide 19 by 7. Place this digit in the quotient on top of the division symbol. Multiply the newest quotient digit (2) by the divisor 7. Subtract 14 from 19. Then you have your answer of 2 5/7.

The last one is correct because the answer is 0.466666666666
12p + 24m = 12(p+2m).
Hope this helps you!
Answer:
a. -2x^2 + 3x+5=y
b.-x^2 +5x-4=y
c.-x^2 +6x-12=y
Step-by-step explanation:
a.y=-2x^2 +bx+c
the points P and Q lie on curve
=> b=3, c=5
b. delta = b^2 +4c
x1= =4
=> =8
x2==1
=>2=b+
suppose : = a
=>
=> a=-3
b=5
a=-3 => =-3 => b^2 +4c =9 =>5^2 +4c=9 => c=-4.
c.vertex (3;-3)
=3 => b =6
= =-3 =>-b^2+4ac=12 => c=-12.
Your answer would be option 2. Use the slope formula to see if any sides are perpendicular. This is because a right triangle must have 2 perpendicular sides that form a 90° angle for it to be a right triangle, so finding these would prove it.
