Answer:
For a unique solution, there must be as many consistent, independent equations as there are variables.
Step-by-step explanation:
Each equation lets you write an expression for one variable in terms of the others in that equation. That expression can be substituted throughout the system, reducing the number of equations and variables by one each.
After n-1 such substitutions in a system of n equations, there will be one equation left. If that is an equation in one variable, then the solution to the system can be easily found. If more than one variable remains (> n variables in n equations), then the system cannot be solved for definitive values of each of the variables.
___
If the equations are inconsistent, there is no solution. If the equations are dependent, then there is no unique solution.
Yes
No
The answer is B (no)
Answer:
Step-by-step explanation:
x=intercept is when the line intersect with the x axis when y=0
6: x intercept (1,0)
y intercept is when the line intersect with y axis at certain point or when x=0
y intercept (0.-24)
5: (0,-4) the y intercept
( 25,0) is the x intercept
21: (0,20) y intercept
(6,0) x intercept
22: (8,0) x intercept
(0 , 4) the y-intercept
Answer:
Step-by-step explanation:
The perpendicular bisectors and angle bisectors are alike in one manners that they both divide the entities they are drawn at.
Perpendicular bisector bisect the sides of triangle in two equal halves and angle bisectors divides the angles to which they are drawn in two equal halves.
The difference is that ,
the point at which perpendicular bisectors meet, is the center of circumcircle which is drawn through the vertices of triangle
the point at which angle bisectors are met, is called the incenter , and is the center of incircle inscribed in a triangle touching its three sides.
Answer: 3.5 h
Step-by-step explanation:
1. Data:
a) s = 740 miles / h
b) d = 2,567 miles
c) t = ?
2. Equation:
3. Solution:
s = d / t ⇒ t = d / s
t = 2,567 miles / (740 miles/h) ≈ 3.47 h ≈ 3.5 h
