Answer:
y = x^2 - 4x - 6.
Step-by-step explanation:
The roots are 2 + √10 and 2 - √10, so in factor form we have:
(x - (2 + √10))(x - (2 - √10))
= ( x - 2 - √10)(x - 2 + √10)
= x^2 - 2x + √10x - 2x + 4 - 2√10 - √10x + 2√10 - √100
= x^2 -4x + 4 - 10
= x^2 - 4x - 6.
One coordinate that is 7 units away from (2,-7) is (2,0). (2,0) is 7 units to the right of (2,-7)
Another coordinate is (9,-7). This one also works.
Multiply the amount she deposits every month by the number of months (m) and add it to her starting amount:
The equation will look like this:
y = 30m + 16
Answer & Step-by-step explanation:
When we see the phrase "rate of change" then it means that we are looking for the slope. So, we will need to know the formula for finding slope or the rate of change.
Now, let's use this equation to solve for the rate of change of each question.
<u>Problem 1:</u>
<em>The rate of change of this equation is 2/3</em>
<u>Problem 2:</u>
<u></u>
<u></u>
<em>The rate of change for this equation is 2</em>
<u>Problem 3:</u>
<u></u>
<u></u>
<em>The rate of change for this equation is 6</em>
Answer:
x^2-16x+64
Step-by-step explanation:
Simplify= (x-8)(x-8)
Simplified= x^2-8x-8x+64
Combine like terms= x^2-16x+64
Basically whenever the sign is squared on the outside it's the equation times itself. Hope this helps.
