Which pair of the following straight lines are parallel and how?
igomit [66]

Answer:

f and b

Step-by-step explanation:

if you put them in y-intercept form, both slopes are 3

In b. it's easy to see that 3x has a slope of 3.

In f. it's not so obvious. Just solve for y or use the shortcut m = -a/b where a is the coefficient of x and  b is the coeff of y.

hence -(6/-2)=3

Make y the subject of the formula <br><br> W= x squared - 2yz
AveGali [126]

Answer:

The formula    y = \frac{x^{2} }{2z} + \frac{W}{2z}

Step-by-step explanation:

<em><u>Explanation</u></em>

Given   W = x² - 2 y z

          2 y z = x² + W

Dividing '2z' on both sides , we get

         \frac{2yz}{2z} = \frac{x^{2} + W}{2z}

⇒       y = \frac{x^{2} }{2z} + \frac{W}{2z}
