get the app "photomath" it will solve all those problems for you. hope it helps. (but also try to learn how to do it because it will help you in the long run)
Answer:
39/37 and 6/5
Step-by-step explanation:
To start, let's assume that 9-8x is positive (we will do this to get rid of the absolute value, but then check later). We get 9(9 - 8x) = 2x + 3, or 81 - 72x = 2x + 3, so 74x = 78 and x = 39/37. If we assume 9-8x is negative, the |9-8x| will turn into 8x-9, so we get 9(8x - 9) = 2x + 3, or 72x - 81 = 2x + 3 , so 70x = 84 and x = 6/5. If we plug the values back in, 9-8(39/37) needs to be positive, which works, and 9-8(6/5) needs to be negative, and this works, so the answers are 39/37 and 6/5.
The value for r is mathematically given as
r<-82

<h3>What are inequalities?</h3>
In mathematics, an inequality is a relation that compares two numbers or expressions in a way that is not equal. The most common use is doing a size comparison between two numbers on a number line.
Generally, eighty-two less than r is less than −164 is mathematically given as
r-82 <-164
r<-82
Therefore
r<-82

Answer:
x = 1 ⇔ y = -2.4
x = 2 ⇔ y = -1.8
x = 3 ⇔ y = -1.2
x = 4 ⇔ y = -0.6
Step-by-step explanation:
→ Rearrange to make y the subject
→ Multiply everything by -1
→ Divide everything by 5
⇒ Substitute x = 1, 2, 3 and 4
