Answer:
Piano Play has the better deal
Step-by-step explanation:
Piano Play has the better deal because it has a lower unit rate
Make Music’s unit rate is 52.5 when you divide $525 by 10 hours
Piano Play’s unit rate is $45 when you divide $540 by 12 hours
Answer: 30
Step-by-step explanation: Before Joe had $45 in total, He then spent it on a movie which is $15. So $45-$15=30
First, lets observe this pattern.
We can notice that each number when multiplied by 3 gives the following number as:
4 x 3 = 12
12 x 3 = 36
36 x 3 = 108
108 x 3 = 324
Based on this, the next number in the pattern will be:
324 x 3 = 972
The right choice is:
c. 972
It is a root of the polynomial if it causes the equation to equal 0.
Let's try each number.
Substituting -3 for x...
(-3)³ - 4(-3)² -11(-3) + 30
-27 - 36 + 33 + 30
0
Therefore, a. -3 is a root to our polynomial.
You could try the rest, but I won't waste time with it. None of the others are roots, and it's multiple choice which means usually just one answer.
