Answer:
x = -y
or
-y = x
Step-by-step explanation:
since you reflect it over the x axis, the y changes to a negative
Answer:
18
Step-by-step explanation:
Let x represent smallest number and y represent second number.
We have been given that the biggest among three numbers is 2.4 larger than the smallest one. So biggest number would be
.
We are also told that 15 times the smallest one is equal to 12 times the second and 10 times the third. We can represent this information in equations as:


Upon solving 2nd equation, we will get:





Therefore, the smallest number is 4.8.
The biggest number would be
.
Upon substituting
in equation (1), we will get:




Therefore, 2nd number would be 6.
Let us find sum of all numbers as:

Therefore, the sum of all 3 numbers would be 18.
Answer:
the missing y is 1 and the missing x is 12 because the unite rate is 2 so 2÷2=1 and 6×2=12
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
y = 3 is a horizontal line parallel to the x- axis
Aline perpendicular to it will be a vertical line parallel to the y- axis with equation
x = c ( c is the value of the x- coordinates the line passes through )
The only equation in this form is
x = 6 → C
