If the problem is 4x=12-5x-30 then
You would add 5x to the 4x; 9x=12-30. Next 12-30; 9x=-18. Now divide nine from both sides to get; x=-2
Answer:
first blank = 10 (for table 1)
second blank = 30 (for table 2)
====================================================
Explanation:
You could use a calculator to determine the value of b, then compute b^x for that first box. But as the instructions state, we don't need to use one. Why is that? Because the tables provide enough information to fill in the blanks.
Table 1 shows x = 2.096 lead to some unknown y value. Meanwhile, table 2 has x = 10 lead to y = 2.096; note the 2.096 shows up again. The exponential and log functions are inverses of each other. They undo each other's operation. This is similar to how division undoes multiplication, and vice versa.
Going in reverse of table 2, we will conclude that 10 must go in the blank for table 1. Therefore, b^x = 10 when x = 2.096
------------
Similarly, we will have 30 in the blank for table 2. Table 1 shows x = 3.096 lead to y = 30. Table 2 is the reverse of that as it is the inverse.
Throughout either section, we didn't need to find the value of b.
Answer:
13. $320
Step-by-step explanation:
First determine how much he made using an estimate
Earnings = hours * rate per hour We estimate 40 hours * 10 per hour
= 40 * 10
=400
Take home after taxes is 4/5 of his earnings
take home = 4/5 * 400
=320
centre: (0,0)
Radius: square root of 30
