1. Points that lie on the intersection area of the inequalities are solutions.
For example (0,2), (-4,4), (2,-1), (-8,0) and all others which lie in this area.
2 Not solutions are points that are on the lines (because we have signs > and <, not ≤ and ≥), or on the areas that are not intercepted. For example, (6,2), (2,2), (2,-4),(-6,-2).
We are given 2 points with there coordinates easy to calculate:
the upper one A(1,15) & the lower one B(6,10). Moreover the equation of this linear function is y = mx + b
1st) calculate m= (10-15) / (6-1) [FOMULA m=(y₂ - y₁) / (x₂ - x₁)]
m= -5/5 ==> m= - 1==> y=-x + b. To calculate b, replace x & y by any of the 2 points A, B. Say A(1,15)
15 = - (1) + b ==> b= 16 & final equation y = -x +16
Answer:
To find the inverse of:
Set the function to y:
Rearrange to make x the subject:
Swap x and y:
Change y to the inverse of the function sign:
Rewrite g(x) as a fraction:
Therefore, as the inverse of f(x) ≠ g(x), the functions are NOT inverses of each other
Answer:
16
Step-by-step explanation:
well, times means to multiply, so 8 times (x) 2 = 16
