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.

If a cube with the length of the side of 4 cm is cut into smaller cubes with the length of the side of 1 cm, then what is the pe

ValentinkaMS [17]

Answer:

300 %

Step-by-step explanation:

Length of the larger cube =4 cm

So volume $V=side^3=4^3=64cm^3$

Length of the smaller cube = 1 cm

Volume of the smaller cube $V=side^3=1^3=1cm^3$

So total number of smaller cube $=\frac{64}{1}=64$

Surface area of the larger cube $A=6\times side^2=6\times 4^2=144cm^2$

Surface area of the 64 smaller cube $A=64\times 6\times side^2=64\times 6\times 1^2=384cm^2$

So percentage increase in surface area $=\frac{384-96}{96}\times 100=300$ %

Which equation represents a linear function?

quester [9]

Answer:

Step-by-step explanation:

y = 9 - X is a linear function; x is to the first power.

y = x2 + 1 does NOT represent a linear function; it's a quadratic function.

o

y=x² + 5 does NOT represent a linear function; it's a quadratic function.

D)

y = [xl - 9 does NOT represent a linear function; it's an absolute value function. This function has two halves, each of which is a linear function.

But the best answer here is that y = 9 - X is a linear function; x is to the first power.

Answer:

It snowed for 6 days in November

Step-by-step explanation:

Since there are 30 days in November

and 20 goes into 100 five times,
