Help me on number problem 4 and 5 please

Mathematics
1 answer:
n200080 [17]3 years ago
7 0

Answer:

4 is decay and 5 is growth

4 has a decay rate of 8 %

5 has a growth rate of 20 %

Step-by-step explanation: The decay rate of 4 is 0.92 and for 5 it is 1.2 It is considered decay if the number with the exponent is less than one because it will decrease the value of y when x or in this case t increase. 5 has a rate of 1.2 and therefore it is growing

.92 *100 = 92

100 - 92 = 8

1.2*100 = 120 - 100 = 20

Solve 5x - 10 <_ 20 pls help
balandron [24]

Answer:

(-∞, 6]

Step-by-step explanation:

Step 1: Write inequality

5x - 10 ≤ 20

Step 2: Solve for <em>x</em>

  1. <u>Add 10 to both sides:</u> 5x ≤ 30
  2. <u>Divide both sides by 5:</u> x ≤ 6

Here we see that any value less than or equal to 6 would work.

∴ the 3rd option is our answer.
