Answer:
5x - 6y = 14
Step-by-step explanation:
The equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
given
y - 1 = 
(x - 4)
Multiply through by 6 to eliminate the fraction
6y - 6 = 5(x - 4) ← distribute
6y - 6 = 5x - 20 ( add 20 to both sides )
6y + 14 = 5x ( subtract 6y from both sides )
14 = 5x - 6y , thus
5x - 6y = 14 ← in standard form
(79 + 93 + 91 + 68 + x) / 5 = 80
(331 + x) / 5 = 80.....multiply both sides by 5
331 + x = 80 * 5
331 + x = 400
x = 400 - 331
x = 69 <=== he would have to make at least a 69
Answer:
<u>Amount in Badria's wallet:</u> 18

<u>Amount in Khalid's wallet:</u> 54
<u />
<u>Amount in Yousif's wallet:</u> 23
Step-by-step explanation:
-multiplicity: the number of times a particular number is a zero for a given polynomial
-affects shape of graph
-odd multiplicity: crosses x axis at root
-even multiplicity: touches x axis at root but doesn't cross it
Isolate the term with 
.
Differentiate both sides with respect to 
.
By the product and chain rules,
Solve for the partial derivative, then evaluate at 
.
