Answer:
1. 3,142 cm^3
Step-by-step explanation:
this is the answer
The discriminant is the part of the quadratic formula underneath the square root symbol: b²-4ac. The discriminant tells us whether there are two solutions, one solution, or no solutions.
First you have to leave your y alone so you want to move the -1. Since you are moving it to the other side it will now become a +1. It will be +1-9 which will equal to -8. Now you have -8=-2y. You want to permanently leave the y alone so now you divide by 2. (-8/-2=-2y/-2) It should be 4=y. That means that 4 is your answer. Remember to make your answer a positive number because it is a negative divided by a negative!
Answer:
y=
x-4
Step-by-step explanation:
is the slope (rise over run)
-4 is the y-intercept
make a point 4 lines above 0,0. from here, make a point 6 spaces right and 7 spaces up. from 0,4 make another point 6 spaces left and 7 spaces down. connect them with a straight edge and draw a line connecting them.
the points will be:
-6,-3
0,4
6,11
