<em>n</em> must be 0, since <em>x </em>ⁿ = 1 for all positive, real <em>x</em> if <em>n</em> = 0. So the answer is A.
Answer:
C. 2x + 6
Step-by-step explanation:
After doing synthetic division (see attached), you get 2, 6, and 0, corresponding to the answer 2x + 6.
Answer:
D. 20 + 2.50x < 50
Step-by-step explanation:
20 + 2.50x < 50 - the sign has to be less than because Millie wants to spend less than $50
Answer:
Solve for y in the second equation
Step-by-step explanation:
We assume your system is ...
Dividing <em>the </em><em>second equation</em> by 3 gives ...
-3x +y = 1
so an expression for y without fractions can be found by <em>solving for y</em>, that is, by adding 3x:
y = 3x +1
_____
<em>Comment on alternate solution</em>
We'd be tempted to solve the first equation for -9x and substitute for that.
-9x = 10 -4y
(10 -4y) +3y = 3 . . . . . substitute for -9x
-y = -7 . . . . . . . . . . . . . simplify, subtract 10
y = 7 . . . . . . . . . . . . . . multiply by -1
Answer:
1
Step-by-step explanation:
Take 4 1/2 and turn it into just halves by multiplying 4•2 and then adding it to one. 9/2 then multiply that by 2 because you need the denominator to be 4 getting 18/4. Then subtract 11/4 you end up getting 9/4. So technically you have 2 pieces but if you want them both to be 11/4 you only have one
