Answer:
A, D
Step-by-step explanation:
Sub the x and y values into the equation. The x value is the first number in the coordinate, and the y value is the second number.
If the left side is equal to the right side, it is a solution.
Example:
4x-5y=24
4(-9)-5(-12)=24
-36+60=24
24=24
Remember: if the left side does not equal the right side, it is not a solution.

y=f (x)=x-7
y=x-7
x=y+7
f^-1 (x)=x+7
28,302,603 in standard word form is: twenty-eight million three hundred two thousand six hundred three.
Less than means minus so 7 less than means -7
-2 times a number x means -2 times x or -2x
is greater than or equal to means <u>></u>
41=41
so
-7+-2x<u>></u>41
-2x-7<u>></u>41
add 7 to both sides
-2x<u>></u>48
divide both sides by -2
remember to flip sign since divided by negative
x<u><</u>-96
