Answer:
y = M X + B
Step-by-step explanation:
y - y1 = m (x - x1)
x1 = 2
y1 = 5
m = 1/7
y - 5 = (1/7) (x - 2)
Answer:
x= 19/4
Step-by-step explanation:
2x+2
Work:
Factor 2x^2+10x+12: 2(x+2)(x+3)
Cancel all x+3, leaving 2(x+2)
2x+2
<span>Simplifying
49x^2 + -9 = 0
Reorder the terms:
-9 + 49x^2 = 0
Solving
-9 + 49x^2 = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '9' to each side of the equation.
-9 + 9 + 49x^2 = 0 + 9
Combine like terms: -9 + 9 = 0
0 + 49x^2 = 0 + 9
49x^2 = 0 + 9
Combine like terms: 0 + 9 = 9
49x^2 = 9
Divide each side by '49'.
x^2 = 0.1836734694
Simplifying
x^2 = 0.1836734694
Take the square root of each side:
x = {-0.428571429, 0.428571429}
