Answer:
- no solutions
- a finite number of solutions
- an infinite number of solutions
Step-by-step explanation:
Your question is very general, including linear and non-linear equations of any number and/or degree. In the general case you're asking about, there will be ...
- no solutions -- no values of the variables satisfy all equations
- a finite number of solutions -- all equations are satisfied for some finite set of variable values
- an infinite number of solutions -- equations are dependent (or periodic*) so the set of solutions is an infinite set
__
For 2 linear equations in 2 unknowns, there will be 0, 1, or infinite solutions.
_____
* Aperiodic equations may also have an infinite number of solutions. 1/sin(x)=0 is an example.
Answer:
6) 20
7) I think is 2.5 (im not sure)
8) 7
Step-by-step explanation:
6) (5x+9)+(3x+11)=180
8x+20=180
-20 -20
8x=160
Divide 8 on each side
x=20
7) (17x+1)=(20x-14)
17x+15 =20x
+17 +17
15 = 37x
divide 15 on each side
X=2.5
8) (3x+3)+(10-4)=90
(3x)+(10x-1)
13x-`1=90
+1 +1
13x=91
Divide 13 on each side
x=7
Answer: 2450.44 ft
Step-by-step explanation:
Formula for SA of a cylinder: A=2*pi*r*h+2*pi*r^2
Formula for radius: diameter/2
Plug height, 17, radius, 13, and pi, 3.14, into the formula above.
= 2450.44 ft
B=1.4
Is the answer.
