Answer:
Step-by-step explanation:
y=2x²-5x-7
y=2x+2
2x²-5x-7=2x+2
2x²-7x-9=0
2x²-9x+2x-9=0
x(2x-9)+1(2x-9)=0
(2 x-9)(x+1)=0
x=9/2 ,-1
y=11 ,0
solutions are (9/2,11),(-1,0)
Solution 1:
100 degrees Celsius is boiling temperature. The boiling temperature in Fahrenheit is equal to 212, so our answer is 212.
Solution 2:
Let us use the formula for converting Celsius to Fahrenheit. Multiply the number of degrees in Celsius by 1.8 (or 9/5) and add 32. Using this approach, we get to the same answer, 212 degrees.
I hope this will help you!

Answer:
okay so I can't see the last option on ur sheet but when u graph this equation the point that lies on the curve is (2,-3) so that is the vertex but if I move up this curved line it passes through the Y axis at (0,-1), the Last answer that I can't see it wouldn't happen to be (-1,6) would it
