question 3: -2
question 4: 0
Ordered pairs in a graph go in the sequence of (x, y)
Answer:
"D"
if you multiply by Conjugate
the denominator would end up A^2 - b^2
the answer has 25 - 10x
that is D
Step-by-step explanation:
<u>Answer:</u>
<u>Step-by-step explanation:</u>
We know that:
First, we need to change the 'y' sign.
- => -y = -x + 6
- => y = x - 6
Now, let's compare both of the equations to find slope.
- => (y = x - 6) = (y = mx + b)
We can see that the slope is 1 and the y-intercept is -6.
<u>Conclusion:</u>
Therefore:
Hoped this helped.
Answer:
Step-by-step explanation:
If x - 1 is a factor of the cubic, then 1 should result in 0 when you put it in the cubic for x. Does it?
f(1) = 2(1)^3 - 15(1)^2 + 22(1) + 15
f(1) = 2 - 15 + 22 + 15
f(1)= 24.
No the result is not zero. So x - 1 is not a factor.
However there must be something that makes this cubic go to zero. The easiest way to find it is to graph it.
The numbers that do make this zero are -0.5, 3, 5
Which mean that the factors are (2x+1)(x-3)(x - 5)
