the third one
Step-by-step explanation:
Answer:
y = -4x + 7
Step-by-step explanation:
As we can see, we want to write the equation of the line
we have this as;
y = -4x + b
To get the y-intercept, we use the values in the point given
we substitute x = 9 and y = -29
So we have;
-29 = -4(9) + b
-29 = -36 + b
b = 36-29
b = 7
So the equation is;
y = -4x + 7
Hey there!
x^2 + 4x = 12
SUBTRACT 12 to BOTH SIDES
x^2 + 4x - 12 = 12 - 12
SIMPLIFY IT
x^2 + 4x - 12 = 0
FACTOR the LEFT SIDE of your EQUATION
(x - 2)(x + 6) = 0
• EQUATION #1: x - 2 = 0
OR
• EQUATION #2: x + 6 = 0
SIMPLIFY IT
• EQUATION #1 answer: x = 2
OR
• EQUATION #2 answer: x = -6
OVERALL ANSWER: x = 2 or x = -6
YOUR ANSWER: x = 2 (Option A.)
Good luck on your assignment and enjoy your day!

Answer:
The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try!
