Answer:
x = 6
Step-by-step explanation:
Equation: <em>x² - 12x + 36 = 0</em>
Quadratic formula: <em>ax² + bx + c = 0 --> x = (-b ± √(b² - 4ac))/2a</em>
Substitute: <em>x = (12 ± √(12² - 4 * 36))/2</em>
Multiply: x = (12 ± √(144 - 144))/2
Subtract: x = (12 ± 0)/2
Solve: x = 6
Answer:
-1
Step-by-step explanation:
Answer:
-23x-40
Step-by-step explanation:
- -5(3x+10)-2(4x-5)
- -15x-50-8x+10
- -23x-40
Subtract 9 so you have -2. Kx=-2 divide both sides by k. You have -2 over k
Answer is slope of 5
Step by step
You can graph the slope as seen on the attached picture. You go up 30, you go right +6. Slope is y/x, so 30/6, equals 5
You can also use the slope formula
(y2-y1) over (x2-x1)
Using points on the graph
(6,0) and (0,-30)
(-30-0 ) over (0-6)
-30 over -6
-30/-6
= 5
