<span> The </span>domain<span> is the set of all possible x-values which will make the function "work", and will output real y-values. The y-values is called the range. Therefore, the range of the function given are as follows:
</span><span>{-17, -7, -2, 3, 13}</span>
<span>(7m^2+ 3m-4)-(3m^2+9m-5)
=</span><span>7m^2 + 3m - 4 - 3m^2 - 9m + 5
= 4m^2 - 6m + 1 </span>
Answer:
x>6
Step-by-step explanation:
We have an inequality here, we need to pay special atention with theirs signs, since they can chance their orientation when multiplying by negative numbers.
4x+5<6x - 7
First step, lets group terms of 'x' variable on one side of the inequality, it is common to put then in the side of the greater term, in our case, this would be the right side since it has 6x. To do this, we can subtract the term '4x' to the whole inequality.
4x+5-4x<6x-4x-7
Thus we have:
5<2x-7
Now lets do the same to free terms, lets sum 7 this time
5+7<2x-7+7
12<2x.
Now, lets divide the expression by 2.
12/2 <2x/2
6<x
Hence our solution is x>6
Answer:
6 percent
Step-by-step explanation:
1 ) 360/9 = 40 - 40 dollars earned per month
2) 40 x 12 = 480 - earned per year
3) 6000/9 = 666.67 x 12 = 8000 per year
4) 480/8000 = 0.06 / 6 percent
Lets check: 6000 x 1.06 = 6360 which is the amount of interest she gets paid in 9 months
It kinda depends on the grade scaling and what percent of your grade test are worth. But I'm guessing it would drop down to a 70% or more.
