Answer: The value of x is 28.

Step-by-step explanation:

Since line m is parallel to line l.

So, we assume that

(3x+21)° and (4x-7)° are corresponding angles.

And we know that , corresponding angles formed when a transversal cut the  parallel line are equal.

So, they must be equal to each other.

3x+21=4x-7\\\\21+7=4x-3x\\\\28^\circ=x

Hence, the value of x is 28.

Step-by-step explanation:

<u>Step 1: Define</u>

Point (6, 2)

Point (9, 8)

<u>Step 2: Find slope </u><em><u>m</u></em>

Simply plug in the 2 coordinates into the slope formula to find slope <em>m</em>

  1. Substitute in points [Slope Formula]:                                                            \displaystyle m=\frac{8-2}{9-6}
  2. [Fraction] Subtract:                                                                                         \displaystyle m=\frac{6}{3}
  3. [Fraction] Divide:                                                                                            \displaystyle m=2

Answer:

B

Step-by-step explanation:

The square of y would look like y^2 and decreased means subtraction

So the equation now y^2-

the quotient of 8 and y would be 8/y

The full equation is y^2-8/y
