Simplify x^3 y^3 / x^3 y^3

Marysya12 [62]

Answer:

$\frac{1}{y}$

Step-by-step explanation:

When simplifying an exponent a way to do is to expand the exponent. This means that it will now be

$\frac{x*x*x*y*y*y}{x*x*x*y*y}$

Whenever you see an x or y on the numerator and denominator cross it out because it is the same thing as 1

When you cross out all of the x's and y's the only variable left is y in the denominator. This means that the answer is $\frac{1}{y}$

Find the value of x.

$\orange{\underline{\huge{\bold{\textit{\green{\bf{FORMULA}}}}}}}$

SUM OF ANGLES ON STRAIGHT LINE = 180°

$\huge\mathbb{\red A \pink{N}\purple{S} \blue{W} \orange{ER}}$

$ANGLES\: R :-( x - 10)°,(3x + 25)°,(x + 5)°, \\ \\ ( x - 10)° + (3x + 25)° + (x + 5)° = 180 \\ 5x + 20 = 180 \\ 5x = 160 \\ x = \frac{160}{5} \\ x = 32° \\$

$\red{ANGLES R :-} \\ \pink{( x - 10)° = 32 - 10 = 22°} \\ \blue{ (3x + 25)° = 32 \times 3 + 25 = 96 + 25 = 121°}\\ \orange{(x + 5)° = 32 + 5 = 37°}$

Write the equation of a line that passes through points (0,4) and (-2,-3) in slope intercept form

Otrada [13]

y=mx+b is the equation of a line;

m=slope , b= y-intercept

You can find the slope with this following equation: (y(2)-y(1))/(x(2)-x(1))

In this case the points are (0,4) and (-2,-3). The first set being (0,4) and the second (-2,-3). This means (0,4) can be expressed as (x(1),y(1)) and (-2,-3) expressed as (x(2),y(2)). Plugging these numbers into the slope equation gives us: (-3-4)/(-2-0) = -7/-2 = 7/2.

m= 7/2 ; so we have : y= (7/2)x+b

We are give a set of points which it passes through, we can simply plug them in:

4 = (7/2)(0)+b (0 is the x and 4 is the y)

We get 4 = 0 +b .... 4=b

our final equation is : y=(7/2)x+4
