We have the following equation:
y = (5-x) / x ^ 2-6x + 5
Rewriting we have:
y = (5-x) / (x-5) * (x-1)
The discontinuity points are:
x = 5
x = 1
x = 5 is removable. For this, we rewrite the function again:
y = (-1 * (5-x)) / (- 1 * (x-5) * (x-1))
y = ((x-5)) / ((x-5) * (1-x))
We cancel similar terms:
y = 1 / (1-x)
Answer:
the points of discontinuity are:
x = 5
x = 1
x = 5 is removable
Answer:
(2, 3 )
Step-by-step explanation:
Given the 2 equations
2x - 3y = - 5 → (1)
5x + 4y = 22 → (2) [ rearranged equation ]
Multiplying (1) by 4 and (2) by 3 and adding will eliminate the term in y
8x - 12y = - 20 → (3)
15x + 12y = 66 → (4)
Add (3) and (4) term by term to eliminate y, that is
23x = 46 ( divide both sides by 23 )
x = 2
Substitute x = 2 in either of the 2 equations and evaluate for y
Substituting into (2)
5)2) + 4y = 22
10 + 4y = 22 ( subtract 10 from both sides )
4y = 12 ( divide both sides by 4 )
y = 3
Solution is (2, 3 )
Answer:
$24.88
Step-by-step explanation:
<u><em>Given:</em></u>
<em>Samantha needs to purchase 7 notebooks at </em>
<em>$2.99 each and 5 pencils at $0.79 each. </em>
<u><em>To Find:</em></u>
<em>About how much will Samantha spend before sales tax?</em>
<u><em>Solution:</em></u>
<em>All we have to do is multiply and then add. </em>
<em>Starting with NoteBook;</em>
<em>Since each notebook cost - $2.99</em>
<em>Then 7 Notebook..</em>
<em>7 × $2.99</em>
<em>= $20.93</em>
<em>Now with Pencil;</em>
<em>Since each pencil cost - $0.79</em>
<em>Then 5 Pencil..</em>
<em>5 × 0.79</em>
<em>= $3.95</em>
<em>As a result, we add both together</em>
<em>$20.93 + $3.95</em>
<em>=$24.88</em>
