Answer:

first you have to find a common denominator like 60. to do this you need to multiply the first fraction by 6 and the second fraction by 5. which will give you the fractions 42/60 and 25/60. which will show you that the first fraction is greater than the second.

How do you do this. Please give a full answer and explain why.

Law of Exponent

$\displaystyle \large{ {a}^{ - n} = \frac{1}{ {a}^{n} } }$

Compare the terms.

$\displaystyle \large{ {a}^{ - n} = {( - 2)}^{ - 3} }$

Therefore, a = -2 and n = 3. From the law of exponent above, we receive:

$\displaystyle \large{ {( - 2)}^{ - 3} = \frac{1}{ {( - 2)}^{ 3} } }$

Exponent Def. (For cubic)

$\displaystyle \large{ {a}^{3} = a \times a \times a }$

Factor (-2)^3 out.

$\displaystyle \large{ {( - 2)}^{ - 3} = \frac{1}{( - 2) \times ( - 2) \times ( - 2)}}$

(-2) • (-2) = 4 | Negative × Negative = Positive.

$\displaystyle \large{ {( - 2)}^{ - 3} = \frac{1}{4 \times ( - 2)}}$

4 • (-2) = -8 | Negative Multiply Positive = Negative.

$\displaystyle \large{ {( - 2)}^{ - 3} = \frac{1}{ - 8}}$

If either denominator or numerator is in negative, it is the best to write in the middle or between numerator and denominators.

Hence,

$\displaystyle \large \boxed{ {( - 2)}^{ - 3} = - \frac{1}{ 8}}$

The answer is - 1 / 8

Which of the following is the point and slope of the equation y - 11 = 3(x + 13)?

4vir4ik [10]

The answer is A.

The equation simplifies to y=3x+50.
So, C is already not an option.

Now we just plug in points to see if the point works for the equation.

A-11=3(-13)+50
11=-39+50

11=11

Thus, this point falls on the line of this equation and is a point.

So, the answer is A.

I hope this helps!

Consider the function y=x^2+5x-2 . What would happen to the graph if (x -1) was substituted in place of the x?

Ilia_Sergeevich [38]

Answer:

Step-by-step explanation:

f(x - c) shift the function c units to the right.

In this case, if (x - 1) was substituted in place of the x, the graph would shift 1 unit to the right.

If you want to graph the new function and know the graph of the previous one, this relationship avoids you the substitution of (x - 1) into the function and expansion of the expression to obtain a new quadratic formula.
