Answer:
x
=
21/2
Step-by-step explanation:
Move all terms not containing x to the right side of the equation.
3x=x+21
Move all terms containing x to the left side of the equation.
2x=21
Divide each term by
2
and simplify.
x
=
21/2
Answer:
Step-by-step explanation:
Use the Pythagorean Theorem to find the zeros of 6x² - 9x - 6.
x = [9±√(9²-4(6)(-6))]/[2(6)] = [9±√225]/12 = [9±15]/12 = 2, -½

there you go, sorry it took so long
Answer:
1. slope= 3/4x Y-intercept= 7
2. slope= 5x Y-intercept=8
3. slope= -2x Y-intercept=0
4. slope= 0 Y-intercept=12
*the table ones are difficult to type out but sorry if it doesnt make sense*
5. X Y=3x+4. Y
0 y=3(0)+4 4
1 y=3(1)+4 7
2 y=3(2)+4 10
3 y=3(3)+4 13
4 y=3(4)+4 16
6. X y=1/2x-1. Y
-2 y=1/2(-2)-1 -2
1 y=1/2(1)-1 1.5
4 y=1/2(4)-1 2
6 y=1/2(6)-1 3
9 y=1/2(9)-1 3.5
7. X. Y=5-2x Y
0 y=5-2(0) 5
1 y=5-2(1) 3
2 y=5-2(2) 1
3 y=5-2(3) -1
4 y=5-2(4) -3
I believe you need the graph for the last 3
