3x+3y=27<br> 3x-3y= -11<br> using elimination
Taya2010 [7]
3x + 3y = 27
3x - 3y = -11
------------------add
6x = 16
x = 16/6 which reduces to 8/3

3x + 3y = 27
3(8/3) + 3y = 27
8 + 3y = 27
3y = 27 - 8
3y = 19
y = 19/3

solution is (8/3, 19/3)

Which graph has a domain of -∞ &lt; x &lt; ∞ and a range of -∞ &lt; y
Alenkasestr [34]

The graph of the option in the question has a domain of -∞ < x < 3.5.

  • Please find attached the drawing of a graph that has a domain of -∞ < x < ∞

<h3>Which method can be used to find the graph that has a domain of -∞ < x < ∞?</h3>

The domain of a graph are the possible x-values that can be obtained from the graph.

A graph that has a domain given by the inequality, -∞ < x < ∞ does not have a vertical asymptote.

An asymptote is a straight line to which a graph approaches, as either the<em> </em><em>x </em>or y-value approaches infinity.

The given graph has a vertical asymptote at <em>y </em>≈ 3.5

The domain of the given graph is therefore, -∞ < x < 3.5

Similarly, the graph has a horizontal asymptote at <em>x</em> ≈ 3

The range of the given graph is therefore, -∞ < y < 3.

A graph that has a domain of -∞ < x < ∞, extends to infinity to the left and the right of the graph.

A function that has a graph with a domain of -∞ < x < ∞ is one of direct proportionality.

An example is, <em>y </em>= x

  • A graph that has a domain of -∞ < x < ∞ is attached.

Distribute then combine like terms : 0.2(3b-15c)<br>​
nignag [31]

Answer:

0.6b - 3c

Step-by-step explanation:

Multiply 0.2 and 3b

0.2 x 3b = 0.6b

Then multiply 0.2 and 15c

0.2 x 15c = 3c

We can't add these, 3c and 6b because they have different letters.

different letter vs. different letter =

don't add

different letter vs. normal number like 5 =

dont add

same letter vs. same letter =

add

normal number vs. normal number =

add

This all goes the same for dividing, subtracting, and multiplying

I hope this helped! :)
