F(x)=-2x2+4x-6
f(0)=-2x2+4x0-6
f(0)=-4+0-6
f(0)=-10

Answer:
The answer to your question is x = 52° and y = 137°
Step-by-step explanation:
Process
1.- Find the value of x using the large right triangle, remember that the sum of the internal angles in a triangle equals 180°.
x + 38 + 90 = 180
x = 180 - 90 - 38
x = 52°
2.- To find y, we notice that x and y -9 are supplementary angles so their sum gives 180°.
x + y - 9 = 180
Substitution
52 + y - 9 = 180
y = 180 + 9 - 52
y = 137°
Paralell to 2x+y=-5
means it has same slope
means it is in form
2x+y=c where we have to find c
convert to slope intercept
minus 2x both sides
xint of 2
xint is where th eline crosses the x axis or where y=0, x=2
2(2)+0=c
2(2)=c
4=c
the equation is 2x+y=4
