Answer:
y = ⅓x
Step-by-step explanation:
Let's find m.
m = y/x
Using the point on the line, (3, 1),
m = ⅓
Substitute m = ⅓ into y = mx
This, the equation that describes the relationship would be:
y = ⅓x
Answer:
If the roots of an equation are x = -1 ± i, it means that the factorized form of that equation is: (x + 1 + i)(x+ 1 - i) = 0.
Using the distributive property, we have:
(x + 1 + i)(x+ 1 - i) = x^2 + x - ix + x + 1 - i + ix + i + 1
Combining like-terms and simplifying:
⇒ x^2 + x + x + 1 + 1 = x^2 + 2x + 2 = 0
Therefore, the stament is correct. If the roots of an equation are x = -1 ± i, then the equation is: x^2 + 2x + 2 = 0.
Answer:209.84 - 20.00 = 189.84 / 2 = 94.92
94.92 + 20.00 = 114.92 Eva spent and Martha spent $94.92
