Answer:
People should be knowledgeable about equations and inequalities because they are often used to solve day to day life problems.
Often times real life problems are modeled using equations and inequalities
Step-by-step explanation:
Inequalities are used often in real life, businesses use inequalities to control inventory, plan production lines, produce pricing models, and for shipping/warehousing goods and materials. Inequalities are used in engineering and production quality assurance.
An equation is the mathematical representation of those two things which are equal, one on each side of an 'equals' sign. Equations are useful to solve our daily life problem.
Answer: conjunction and -20<x <16 is answer.
Step-by-step explanation:
It is a conjunction because it is and statement
|x+2|<18 gives
[Since l x-a l <b means x-a lies between -b and b ]
-18<x+2<18
subtracting 2 in the whole inequality ,we get
-18-2 <x +2-2 < 18-2
-20 < x < 16
Answer:
46 is the answer
Step-by-step explanation:
Because:
a2 + c(2+b)
3(2) + 5(2+6)
6 + 5(8)
6 + 40
46
Answer:
y = (√x)/13 for x > 0
Step-by-step explanation:
Actually, this is f(x) = 169x^2; the " ^ " indicates exponentiation. The graph consists of the right-hand half of the parabola 169x^2. Before we attempt to find the inverse function, we determine whether or not this function passes the vertical line test. If x is restricted to (0, infinity), a horizontal line intersects this graph only once. Therefore, this function has an inverse.
1. Replace 'f(x)' with 'y:' y = 169x^2
2. Interchange x and y: x = 169y^2
3. Solve for y: y^2 = x/169, or y = (√x)/13 for x > 0
