Simplify this expression. Assume that x is nonzero.<br> x^−11•x^2
sergey [27]

Answer:

Step-by-step explanation:

I'm assuming that you meant:  x^(-11)*x^2.  Here there's a common base:  x.

Then this expression becomes x^(-11*2)*x^2.  We need only combine (add up) the exponents of x:  x^(-11*2)*x^2 = x^(-11 + 2) = x^(-9).  Use of parentheses as shown is important here.

Note that x^(-9) is the same as

         1

   ------------

        x^9

Jasmine can run 4 5/6 miles in 2/3 of an hour. how many miles can she run 1 hour simplify comepletly
Vikentia [17]

Remark

the question depends on d= r * t

d = the distance in miles.

r = the rate of travel in miles per hour

t = the time in hours.


Step One

Rearrange the formula so you are solving for the rate.


d = r * t Divide by t

4 5/6 = (4*6 + 5)/6 = 29/6


r = d / t


Step Two

Substitute into the equation.

r = \dfrac{\dfrac{29}{6}}{\dfrac{2}{3} }


Step Three

Turn the bottom fraction upside down. Multiply these two together.


r = \dfrac{29}{6} * \dfrac{3}{2}


r = 29/4 miles hour.


Step Four

Solve for d when t = 1 hour.


d = ??

r = 29/4 miles / hour

t = 1 hour.


d = 29/4 * 1

d = 29/4 miles


That's as simple as you can get it unless you want 7 1/4 miles or 7.25 miles

When graphed in the (x,y) coordinate plane, at what point do the lines x - y = 12
Alex17521 [72]

Answer:

(14, 2).

Step-by-step explanation:

x - y = 12

y = 2

Solving this system:

Plug y = 2 into the first equation:

x - 2 = 12

x = 14.

Therefore the  point of intersection is at (14, 2).

(2^3)^7 (2^-9)^2 how do i put that in exponential form​
jok3333 [9.3K]

Answer:

2³ = 8

Step-by-step explanation:

According to the laws of exponents, when raising a power to another power, you need to multiply the exponents.  After you multiply each set of exponents by the additional power, then it become a multiplication problem where the base is the same.  When multiplying exponents with the same base, you keep the base and add the exponents:  

(2^{3})^{7}*(2^{-9})^{2}=2^{21}*2^{-18}=2^{21+-18}=2^{3}
