Answer:
20 - 17
Step-by-step explanation:
In this expression, decrease means to subtract or take away.
So, you would write this equation in order, 20 - 17
Thus, 20 - 17 is the answer
Answer:
Y= 2X
Step-by-step explanation:
The Y intercept is 0, therefore it would not have a "b" if it were in the form y=mx+b.
The line is going right, so it's positive. From 0, the line goes over 2, up 2, so the slope is 2.
Yes, there are many possible answers. An equation that can model your situation is:
4a+4b=75, with a being the amount of adult tickets sold, and b being the amount of children’s tickets sold.
Because both tickets cost 4 dollars, you would multiply the amount of tickets sold, by the price (in dollars) of the ticket.
So, you can find possible answers by substituting the amount of adult tickets sold. Say, 4 adults bought tickets. You could then substitute a for 4. So the equation would look like this.
4(4)+4b=75
16 + 4b = 75
4b = 75 - 16
4b = 59
Divide each side by four
B = 14.75
The reason you got a decimal number is because 75 cannot be divided by 4 evenly. So, in this context, you could say that 15 children bought tickets. One child had an issue, and Lisa gave them a 25% discount. This would explain why there are only 75 dollars worth in tickets. I hope I helped, this is my first question I have ever answered so I’m not entirely sure if this was helpful or not. Hope you figure this out!
Answer:
Correct answer is:
b) (-5, -3)
Step-by-step explanation:
Given that area of square is <em>36 </em>and one sides lies along the line <em>y = 3</em>
<em>To find:</em>
Possible location of a vertex can be = ? Answer to be chosen from the options:
a) (9, 4)
b) (-5, -3)
c) (6, 5)
d) (3, 6)
<u>Solution:</u>
First of all, let us try to find the side of square.
Now, given that one side lies on the line y = 3 that means 2 of its coordinates will have their y - coordinates as 3.
Now, we know that all the angles of a square are .
So, coordinates of adjacent vertices will have a change in only x value or either y value.
Therefore, we can say that The other two coordinates of the square will have the y coordinates the value either 3 + 6 = 9 or 3 -6 = -3
One such possible square is attached in the answer area.
possible location of the one of the vertex is:
<em>b) (-5, -3)</em>
16 = -5 + z/4
21 = z/4
21*4 = z
z = 84
