Answer: y = (xm)/3 + b

Step-by-step explanation:

1. Multiply m on both sides

x × m = 3(y - b)

2. Divide by 3 on both sides

(xm)/3 = y - b

3. Add b on both sides

y = (xm)/3 + b

Answer:

\frac{\sqrt{17} }{7}

Step-by-step explanation:

Using the Pythagorean identity

sin²x + cos²x = 1, then

sinx = \sqrt{1-cos^2x}

Note that (\frac{4\sqrt{2} }{7})² = \frac{32}{49}

sinΘ = \sqrt{1-(32/49)}

        = \sqrt{\frac{17}{49} } = \frac{\sqrt{17} }{7}

What is the value of n in the equation 0.2(n - 6) = 2.8?<br> (1) 8 (3) 20<br> (2) 2 (4) 44
trapecia [35]
Solve for n.

0.2(n - 6) = 2.8

Distribute

0.2*n - 0.2*6 = 2.8
0.2n - 1.2 = 2.8

Now inverse operation should be applied

0.2n - 1.2 = 2.8
         + 1.2   +1.2

2.8 + 1.2 = 4

0.2n = 4
0.2n/0.2 = 4/0.2
n = 20

Answer: 20
