If there were 30 Girls, 4 Girls played for each part.
For this case we have that by definition, the equation of a line in the slope-intercept form is given by:
Where:
m: Is the slope
b: Is the cut-off point with the y axis
We have the following equation:
We manipulate algebraically:
We subtract 10 from both sides of the equation:
We subtract 3x from both sides of the equation:
We multiply by -1 on both sides of the equation:
We divide between 5 on both sides of the equation:
Thus, the equation in the slope-intercept form is 
Answer:
Answer: 42.
Step-by-step explanation:
Answer: Hello mate!
we know that p(x,y) means "Student x has taken class y"
and the used symbols are:
∃: this means "existence", you use this symbol to say that there exists at least one object that makes true the sentence.
∀: this means "for all", you use this symbol to say that the sentence is true for all the elements, then:
a) ∃x∃yP (x, y)
"exist at least one student x, that took at least one class y"
b) ∃x∀yP (x, y)
"exist at least one student x, that took all the classes y"
c) ∀x∃yP (x, y)
"every student x, took at least one class y"
d) ∃y∀xP (x, y)
"exist at least one class y, that has been taken by all the students x"
e) ∀y∃xP (x, y)
"for every class y, there is at least one student x that took the class"
f) ∀x∀yP (x, y)
"all the students x took all the classes y"
We are given :
The cost of one adult ticket = a.
The cost of one child ticket = c.
<u>Roy buys</u>
6 adult tickets and 2 child tickets.
Total amount = $66.
Therefore, first equation for Roy total amount would be
<em>6a +2c = 66 --------------------(1)</em>
<u>Elisa buys</u>
5 adult tickets and 4 child tickets.
Total amount = $62.
Therefore, second equation for Elisa total amount would be
<em>5a +4c = 62 --------------------(1).</em>
Therefore,
<h3>Roy
<u>6</u>a + <u>2</u>c = <u>66</u></h3><h3>
Elisa <u>5</u>a + <u>4</u>c = <u>62.</u></h3>
