Exponent rule : a^-x = 1/a^x
x^-9 * x^-2 =
1/x^9 * 1/x^2 = (when multiplying exponents with same base, add exponents)
1/x^(9 + 2) =
1/x^11
Answer:
Anything after x determines if it goes up since it's a positive 5 it's 5 units up
Answer:
25 cm
Step-by-step explanation:
the whole parallelograph is 5 times 10 which equals 50. Devide that by 2 and you get 25
Answer:
The ordered pair is not a solution of the equation
Step-by-step explanation:
we know that
If a ordered pair is a solution of a linear equation, then the ordered pair must satisfy the linear equation
we have

Substitute the value of x and the value of y of the given ordered pair in the linear equation and analyze the results
For x=-1, y=15


----> is not true
so
the ordered pair not satisfy the equation
therefore
The ordered pair is not a solution of the equation
check the picture below, that's pretty much the same block, or "rectangular prism", with a width of 10, length of 5 and height of 1.
so anyhow, is really 6 rectangles stacked up to each other at the edges, so, we can simply get the area of each of those rectangles, add them up and that's the surface area.
front and back, two rectangles of 5x1
left and right, two rectangles of 1x10
top and bottom, two rectangles of 10x5
