What do we know about those two lines?
They are perpendicular, meaning they have the same slope.
We know the slope of both is not zero (neither is vertical).
Therefore either
1) Both slopes are positive and therefore the product is positive
2) Both slopes are negative and therefore the product is positive (minus by a minus is a plus)
For the y intercepts, we know that the line P passes through the origin.
Therefore its Y intercept is zero.
[draw it if this is not obvious and ask where does it cross the y axis]
Therefore the Y intercept of line K and line P is zero.
[anything multiplied by a zero is a zero]
So we know that the product of slopes is positive, and we know that the product of Y intercepts is zero.
So the product of slopes must be greater.
Answer A
Answer:
Explanation:
In this case, you need to solve for y in y + y/a = b, if s ≠ - 1.
This is how you do it step-by-step:
<u>1. Multiply all the equation by the common denominator</u>: a
<u>2. Simplify</u>:
<u>3. Common factor:</u> y
<u>4. Divide both sides by a + 1</u>
Answer:
2(x + 3) <9
Step-by-step explanation:
<u>Two times</u> the <em>quantity of a number increased by 3</em> is <u>less than 9</u>
2 · (x + 3 ) < 9
= 2(x + 3) <9

Answer:
The domain is all real numbers
Step-by-step explanation:
f(x) = x^2 +6x +8
The domain is what numbers can we put in for x
This is a parabola, we can put in any number for x and the function is defined
