Answer:
Distribute:
=(−2)(4x)+(−2)(−4)+x
=−8x+8+x
Combine Like Terms:
=−8x+8+x
=(−8x+x)+(8)
=−7x+8
Step-by-step explanation:
Answer: The solution to the system is (-2, 3)
Step-by-step explanation: In order to graph these equations, plug in any numbers for the value x to solve for the y value. For example, you can choose x to equal -1. Solve for this in both equations: y = -2(-1) - 1 and y = -1 + 5.
Y = -2(-1) - 1
Y = 2 - 1
Y = 1
Y = -1 + 5
Y = 4
Graphing this, you can see the values (-1, 1) for y = -2(-1) - 1 (blue) and (-1, 4) for y = -1 + 5 (red). Continue to solve for y using a variety of x values until you find where both lines cross each other.
As long as u multiply both the numerator and denominator by the same number, it will be equal.
Answer:
R: (-3, -4)
S: (-3, -1)
T: (1, -4)
Step-by-step explanation:
You would subtract 1 from all the initial x values, and 5 from all the initial y values
