Answer:
{x | x > -4}
Step-by-step explanation:
The direction of the < or > sign only changes when numbers are multiplied or divided by negatives.
Because to simplify 9x > -36 you only need to divide by 9, the sign stays the same and the numbers are simply divided:

x > -4
So the solutuon set would be:
<h3>{x | x > -4}</h3>

Answer:
Step 1: 8 + 16x Step 2: 4(4) + 4(12x) Step 3: 4(4 + 12x) Step 4: Dimensions of the rectangle are 4 and 4 + 12x In which step did the student first make an error and what is the correct step? Step 3; 4 + (4 + 12x) Step 3; 4 + (4 ⋅ 12x) Step 2; 4(2) + 4(4x) Step 2; 4(2) + 4x(2)
Answer:
Step-by-step explanation:
An exponential function is of the form

where a is the initial value and b is the growth/decay rate. Our initial value is 64. That's easy to plug in. It goes in for a. So the first choice is out. Considering b now...
If the rate is decreasing at .5% per week, this means it still retains a rate of
100% - .5% = 99.5%
which is .995 in decimal form.
b is a rate of decay when it is greater than 0 but less than 1; b is a growth rate when it is greater than 1. .995 is less than 1 so it is a rate of decay. The exponential function is, in terms of t,
