Can some answer this math question

-BARSIC- [3]

Answer:

A

Step-by-step explanation:

To multiply powers of a variable, add the exponents:

$x^m\cdot x^n = x^{m+n}$

This rule works for all exponents, positive, negative, or zero. Also, remember that $x^0=1$ .

Also, remember the definition of negative exponent: $x^{-n} = \frac{1}{x^n}$

To multiply the two monomials, start by multiplying the coefficients, 14 and 4. That gives 56, so your answer begins with 56.

Now for the powers of x, $(x^3)(x^{-5}) = x^{3+(-5)} =x^{-2} = \frac{1}{x^2}$

For the powers of y, $(y^{-4})(y^4)=y^{4+(-4)} = y^0 = 1$ $(y^{-4})(y^4) = y^{-4+4} = y^0 =1$

Your answer is

$56 \cdot \frac{1}{x^2} \cdot 1 =\frac{56}{x^2}$

Which of the following is the equation of a line that passed though the points (2,5) and (4,3)

STatiana [176]

The correct answer is C as it has the same line of equation. We can make this clear by verifying that these two points make the same equation or not. So as we can see if we calculate the gradient using the formula y2 - y1 / x2 - x1.

As we now know that the gradient is -1. We can simply put any one point in the equation y - y1 = m(x - x1) to get the line of equation. WHen we calculate the line of equation it come out to be y = -x + 7

Answer:

$\huge{ \boxed{ \bold{ \tt{m \angle \: abc \: = 35 \degree}}}}$

Option C is the best choice.

Step-by-step explanation:

✺ First , Let's know about Corresponding angles :

A pair of interior and exterior angles which lies to the same side of a transversal.
Remember that the corresponding angles are always equal.
The easiest way to think of corresponding angles is the 'F - Pattern'.

✎ Now, In our case , x ° and ( 3x - 70 ) ° are corresponding angles. Set up an equation and solve for x.

$\sf{x = 3x - 70\: ( \: being \: corresponding \: angles})$
