Answer:
-3/1 and -2/1
Step-by-step explanation:
Answer:
a.
b.
Step-by-step explanation:
We are given that a line
a. We have to find the equation of resulting line when the given line is dilated by a factor of 2.
We know that when a line is dilated by a then equation of line is given by
We have a=2
Then, equation of line after dilation
b.We have to find the equation of line when resulting line is translated 3 units up
Transformation rule when the y shift 3 units upward is given by
When the line is translated 3 units up then the equation of line is given by
The quadratic formula is:
(-b ± √b² - 4ac)/2a
So first we need to find what a, b, and c are by making the equation equal to 0.
We can do this by adding 13x and subtracting 10 to get -7x² + 13x - 10, so your values would be a = -7, b = 13, and c = -10.
Now you can just substitute them into the equation:
(-13 ± √13² - 4 × -7 × -10)/-14
I believe that is your answer in standard form, so I hope this helps!
