Its a trick question, 15% of 6th grade teachers give HW, but there are 12 teachers. its not gonna be 15% of 12, because you would also get a fraction of a teacher.

Answer:

(i)(a - 2y) (3x - 4b)

(iii) (m - n)(m + 4)

Step-by-step explanation:

(i)

3ax - 6xy + 8by - 4ab

= 3x (a - 2y) - 4b (-2y + a)

= 3x (a - 2y) - 4b (a - 2y)

= (a - 2y) (3x - 4b)

(iii)

[tex] {m}^{2} - mn + 4m - 4n \\ \\ = m(m - n) + 4(m - n) \\ \\ = (m - n)(m + 4)[/tex]

Answer: correct answer is C

Step-by-step explanation:

The value of m in the figure is √126.

Option C is the correct answer.

A triangle is a 2-D figure with three sides and three angles.

The sum of the angles is 180 degrees.

We can have an obtuse triangle, an acute triangle, or a right triangle.

We have,

ΔABD is similar to ΔBCD.

This means,

The corresponding sides ratio is equal.

AB/BC = BD/CD = AD/BD

AB/m = BD/7 = 11/BD

Now,

BD/7 = 11/BD

BD² = 77

BD = √77

Now,

ΔBDC

BC² = CD² + BD²

m² = 7² + 77

m² = 49 + 77

m² = 126

m = √126

Thus,

The value of m in the figure is √126.

B. Same-side interior angles

Step-by-step explanation:

Angle w and angle x lie on the same side of the transversal that cut across the two parallel lines, and are also within the two parallel lines. They are therefore regarded as same-side interior angles. Same-side interior angles are supplementary.

Step-by-step explanation:

The graph of the function f (x) = 4/x is shown in figure.

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given that;

The function is,

⇒ f (x) = 4 / x

Now, We can draw the function f (x) = 4 / x.

Hence, The graph of the function f (x) = 4/x is shown in figure.

Answer:

  (x, y) = (3, 7)

Step-by-step explanation:

If you divide the second equation by 2, it becomes ...

 -x +2y = 11

Adding this to the first equation gives you the value of y:

  (x -y) +(-x +2y) = (-4) +(11)

  y = 7 . . . . . . . . simplify

The first equation can be rearranged to give an expression for x:

  x = y -4

  x = 7 -4 = 3

Then the solution is seen to be (x, y) = (3, 7).
