Answer:
-n← 2 2/3
Step-by-step explanation:
first combine like terms, and then simplify
y = (t x - m -s)/r
Step-by-step explanation:
Step 1 :
Given,
r y + s = t x - m
=> r y = t x - m -s
=> y = (t x - m -s)/r
Step 2 :
A) r can take any values except 0.
This is because when r = 0, the denominator becomes 0 and division by 0 is undefined
The limitation for r is r should not be equal to 0
The other variables can take any value. Hence the other variables do not have any limitation
Third option: Elsa lost four points on the last math quiz, and Marc lost seven points. How many total points did they lose?
The domain of the function is x ≤ 6.88
The domain of the function is y ≤ 20
<h3>Domain and Range</h3>
- These are input and output values for which the function exists
Given the function of x expressed as:
y = 3.5x + 2.8
The domain occurs at the point where 3.5x + 2.8 ≤ 20
3.5x ≤ 20 - 2.8
3.5x ≤ 17.2
x ≤ 6.88 - Domain
This given the domain of the function.
The range of the function is the point where y ≤ 20

Answer:
Step-by-step explanation:
4x + 15 = 3
Subtract 15 from both sides
4x + 15 - 15 = 3 - 15
4x = -12
Divide both sides by 4
4x/4 = -12/4
x = -3
Check:
substitute x = -3 in the LHS of the equation,
4*(-3) + 15 = -12 + 15
= 3 = RHS
