The answer of -3(8/9) ÷ 66.9[9 (-8.9 + 9/5) .01] is 0.06237948089

Step-by-step explanation:

To solve this problem -3(8/9) ÷ 66.9[9 (-8.9 + 9/5) .01] we must start with

1. Solve this bracket [9 (-8.9 + 9/5) .01] at first

2. Multiply the answer of the bracket by 66.9

3. Multiply -3(8/9) and divide the answer by the product of the previous

   step

In [9 (-8.9 + 9/5) .01]

∵ (-8.9 + 9/5) = (-8.9 + 1.8) = -7.1

∴ [9 (-8.9 + 9/5) .01] = [9 (-7.1).01]

∵ 9(-7.1)(.01) = -0.639

∴ [9 (-8.9 + 9/5) .01] = -0.639

∵ 66.9 [-0.639] = -42.7491

∵ -3(\frac{8}{9})=\frac{-8}{3}

∴ -3(8/9) ÷ 66.9[9 (-8.9 + 9/5) .01] = \frac{-8}{3} ÷ -42.7491

∴ -3(8/9) ÷ 66.9[9 (-8.9 + 9/5) .01] = 0.06237948089

The answer of -3(8/9) ÷ 66.9[9 (-8.9 + 9/5) .01] is 0.06237948089

What is the slope of the line that passes through (8,5), (-7,20)?
Kaylis [27]
-1, because the equation for the slope is y2-y1/x2-x1. So let's bring the y value in the second set of point, which is 20, and bring the first y value in the first set of points, which is 5. 20-5 is 15. Now let's subtract the x values. So the second x from the second parentheses x value is -7, and the first x value from the first parentheses is 8. -7-8 is -15. Now we have this division equation, 15/-15, which is -1. So therefore, the slope of the line will be -1.
