Your given expression has no "b", so you can rule out selections b, c, e.
The expression is not equal to 1, so you can rule out selection a.
That leaves selection d, which is the correct choice:
... d. 1/x^a
_____
The rule for exponents is that an exponent in the numerator is the same as its opposite in the denominator, and vice versa.
The exponent of <em>-a</em> in the numerator is the same as an exponent of <em>a</em> in the denominator.
20+2x/5-x
Start by writing it as a fraction
20 + 2/5x (fraction) - x
Next you calculate the difference
20 - 3/5x (fraction) is the answer
The slope would be:
-5--3/3-1
-2/2
-1
Slope = -1
Answer:
there are no solutions
Step-by-step explanation:
x-3y=-3
-2x+6y=12
multiply the first equation by 2
2( x-3y)=-3*2
2x-6y = -6
add the 2 equations together
2x-6y = -6
-2x+6y=12
-------------------
0 = -6
this is not true
so there are no solutions
