Step-by-step explanation:
For Problem 1, the work is as follows:
[tex]2(3x-1)+x\\Distribute\\6x-2+x\\7x-2[/tex]
For Problem 2, the work is as follows:
[tex](3x^{2} +6x+4) - (-x^{2} +2x-1)\\Distribute -\\(3x^{2} +6x+4) + (x^{2} -2x+1)\\Combine\\4x^{2} +4x+5[/tex]
For Problem 3, the work is as follows:
[tex]5b-(a+c)^{2} \\5(3) - (-1+-4)^{2} \\15 - (-5)^{2} \\15-25\\-10[/tex]
For Problem 4, the work is as follows:
[tex]4x-8 = -12\\+8\\4x = -4\\-4/4 = -1\\x = -1[/tex]
For Problem 5, the work is as follows:
[tex]\frac{1}{2} (12x-6) = 2x-15\\Distribute\\\\6x - 3 = 2x -15\\+3\\6x = 2x -12\\-2x\\4x = -12\\-12/4\\x = -3[/tex]
For Problem 6, the work is as follows:
[tex]17 *0.06 = 1.02\\17+1.02 = 18.02[/tex]
For Problem 7, the work is as follows:
[tex]x = (2,0)\\y = (0,-1)\\\frac{rise}{run} \\y = \frac{1}{2} x-1[/tex]
For Problem 8, the work is as follows:
[tex]y_{2} -y_{1} \\x_{2} -x_{1} \\-1-1 = -2\\0-(-2) = 2\\Slope = -1[/tex]
For Problem 9, the work is as follows:
[tex]3y - 2x +6 = 0\\-3y\\(-3y - -2x+6)/-3\\y = \frac{2}{3} x -2[/tex]
For Problem 10, the work is as follows:
[tex](y-3) = -2(x-1)\\Distribute\\(y-3) = -2x+2\\+3\\y = -2x +5[/tex]
Hope this Helps!
