Answer is B)
Answer:
(-2, 3)
Step-by-step explanation:
4x + 5y = 7
3x - 2y = -12
Let's solve this by elimination. We want to eliminate one variable at a time. This means we need to multiply the equations to create a common multiple to cancel out a variable.
Let's work with y.
5y and -2y: For these values to cancel out, we need to multiply each term to create a common multiple.
2(4x + 5y = 7)
5(3x - 2y = -12)
Multiply.
8x + 10y = 14
15x - 10y = -60
Eliminate.
23x = -46
Divide both sides by 23.
x = -2
Now that we know x, let's plug it back into one of equations to find y.
4x + 5y = 7
4(-2) + 5y = 7
Multiply.
-8 + 5y = 7
Add.
5y = 15
Divide.
y = 3
Now we know x and y; let's plug both back into the equation we have not checked yet.
3x - 2y = -12
3(-2) - 2(3) = -12
Multiply.
-6 - 6 = -12
Subtract.
-12 = -12
Your solution is correct.
(-2, 3)

Answer:
1. Pattern. 2. I don't know that one
Step-by-step explanation:
For finding the rate with a table all you do is look how far the numbers are jumping each time. Example: x: 1, 3, 5, 7, 9 y: 2, 4 ,6 ,8 , 10
Both the x and y follow a pattern, though its not the same, its still a pattern
(The Constant rate of change for x is 2 as it goes up 2 every time and the constant rate of change for y is also 2 as it goes up by 2 every time
