Answer:
Ok, the domain is the set of values that we can input in a function.
In this case, we have:
y = Ix - 6I + 3.
Notice that there is no restriction here, x can actually take any value, then the domain will be the set of all real numbers.
The correct domain is x, x ∈ R
Now, if we had (for example) something like:
y = Ix - 6I < 3
Now we have a restriction in the domain because we can not have y equal or larger than 3.
To find the domain, we can break the absolute value:
Ix - 6I < 3
is equivalent to:
-3 < x - 6 < 3
now let's add 6 in each side.
-3 + 6 < x - 6 + 6 < 3 + 6
3 < x < 9
That will be the domain in that case.
Answer:
- D. l = 3 || 4 < c < y || 8l + 7.5c ≥ 70
Step-by-step explanation:
<h3>Work at library</h3>
- Time = 3 hours ⇒ l = 3
- Payment = $8 per hour
- Total payment = 8l
<h3>Work at coffee shop</h3>
- Time = between 4 and 7 hours ⇒ 4 < c < 7
- Payment = $7.5 per hour
- Total payment = 7.5c
Target income = at least $70 daily
<u>So the system as per above parameters:</u>
- l = 3
- 4 < c < y
- 8l + 7.5c ≥ 70
Correct option is D
Answer:
the answer would be A.
Step-by-step explanation:
because the number of books(n) times 2, because they have twice the number of books divided hy fifteen so fifteen is below the line. im bad at explaning trust me
Answer: I hope this helps :)
Substitution: 45+15(6-1)
Simplify: 120
Step-by-step explanation:
Calculate within parenthases (6-1) =5 =45+15(5)
Multiply left to right 15(5)=75 =45+75
Add leftg to right 45+75=120
Answer = 120

Answer:
x<7
Step By Step Answering:
Step 1: Simplify both sides of the inequality.
x+10<−4x+45
Step 2: Add 4x to both sides.
x+10+4x<−4x+45+4x
5x+10<45
Step 3: Subtract 10 from both sides.
5x+10−10<45−10
5x<35
Step 4: Divide both sides by 5.
5x/5<35/5
x<7
