Question #1:
a)
(4, 2)
Both of these are positive, and when x and y are both positive they're both in Quadrant 1.
b)
(x + 1, y - 5)
Add 1 to 'x', subtract 5 from 'y':
(4 + 1, 2 - 5)
(5, -3)
x is positive and y is negative, that means this will be in Quadrant 4.
c)
Reflection Across y-axis:
(-x, y)
Multiply -1 to 'x':
(5 * -1, -3)
(-5, -3)
Both of these are negative, if both x and y are negative it's located in Quadrant 3.
Question #2:
No, that can't tessellate a plane. We can't cover up space so there are no overlaps or gaps.
Answer:
7.9 ounces
Step-by-step explanation:
Hello, great question. These types are questions are the beginning steps for learning more advanced Equations.
For this problem we can use a simple Rule of Three property to solve this problem.
=
Now we cross multiply 3.5 by 39.5 and then divide the answer by 17.5 to get x like so,
Finally, we can see that 7.9 ounces should be added to the 39.5 gallons of gasoline.

Answer:
4
Step-by-step explanation:
The total number of students in the maths club is 40
the number of boys is 5 less than 2 times the amount of girls
to find the number of girls and boys let the number of girls be X.
so 2X-5= the number of boy
so, X+ 2X-5=40
3X-5=40
3X=40+5
3X=45
X=45/3
X=15
the number of girls is 15
and the number of boys is 15x2-5=25 boys
