Answer:
So do you want the roots? If so it is
x ≈ −
1.37049747
, 1.13336413
but rounded is x = -1 ; x = 1
Step-by-step explanation:
Answer:
x=3/7 y=37/7
Step-by-step explanation:
7x=13 x=13/7
2y-3*13/7=5
14y-39=35
14y=74
y=74/14=37/7

Answer: x+4</h3>
This is because the given expression factors to (x+4)(x+4), which condenses to (x+4)^2.
To factor, think of two numbers that A) multiply to 16, and B) add to 8. Those values would be 4 and 4
4+4 = 8
4*4 = 16
So that's how we end up with (x+4)(x+4). You can use the FOIL rule to expand that out and get x^2+8x+16 again to help verify you have the correct factorization.
Answer:
y = 5 - 4x is linear because the x is to the power of 1.
