What are the different types of solutions that you can get when you solve a system of linear equations? Describe the graphs of these different types of systems.

jekas [21]3 years ago

Answer:

  • there are no solutions (lines do not intersect)
  • there is one solution (lines intersect at one point)
  • there are an infinite number of solutions (lines overlap—are the same line)

Step-by-step explanation:

"A system of linear equations" covers a lot of territory. In Algebra 1, it usually means two linear equations in two unknowns. Each of those equations will graph as a line on a coordinate plane.

A solution is a point that satisfies all the equations. That is, it is a point that is on all the lines described by the system of equations.

The geometry of lines on a plane comes into play with regard to solutions.

  • The lines may be parallel, hence never intersect. (<em>No points</em> will be on all the lines.)
  • The lines may intersect at <em>one point</em>.
  • The lines may be the same line, overlapping, identical, coincident, consisting of <em>all the same points, an infinite number</em>.

Match the graph to one of the exponential functions .
Ipatiy [6.2K]

Answer:

The second possible answer is the correct one.

Step-by-step explanation:

The second possible answer is the correct one.  As x increases, 4^x increases exponentially.  However, in this case there's a negative sign in front of 4^x, so we know that the graph follows an exponential trajectory downward.  Also note that 4^0 = 1, so 1 - 4^x = 0 at x = 0.

F ( x ) = x 2 + 6 x and g ( x ) = x − 8 , calculate. f ( g ( − 5 ) ) =
BlackZzzverrR [31]

\qquad\qquad\huge\underline{{\sf Answer}}

Let's solve ~

First we have to calculate g (-5) :

\qquad \tt \dashrightarrow \:x - 8

\qquad \tt \dashrightarrow \: - 5 - 8

\qquad \tt \dashrightarrow \: - 13

Now, let's find f (g (-5)) :

\qquad \tt \dashrightarrow \: {x}^{2}  + 6x

\qquad \tt \dashrightarrow \:( - 13) {}^{2}  + (6 \times  - 13)

\qquad \tt \dashrightarrow \:169 + ( - 78)

\qquad \tt \dashrightarrow \:169 - 78

\qquad \tt \dashrightarrow \:91

Find the surface area of the following triangular pyrarnid using the net.
JulsSmile [24]

Answer:

B 84 is our answer

Step-by-step explanation:

triangle formula for surface area is base x height divided by 2 so 7 x 6 = 42 42 ÷ 2 = 21 All the other triangles are going to be the same so 21 x 4 = 84 so 84 is our surface area
