Answer:
5+√97/4
Also 5-√97/4
Step-by-step explanation:
The Quadratic formula is x=-b+-√b^2-4ac/2a
This means that we should plug the values for A B AND C into the formula
We can work out that
<u><em>A = 2</em></u>
<u><em>B=-5</em></u>
<u><em>C=-9</em></u>
Once we have put these into the formula we get
5+√97/4 (all over 4) aka 3.71
Also 5-√97/4 (all over 4) aka -1.21
Answer:
negative slope
Step-by-step explanation:
you have to subtract
<em>The regular price was $110</em>
- <em>Step-by-step explanation:</em>
<em>Hi there ! </em>
<em />
<em>60% .......... $66</em>
<em>100% ..........$ x</em>
<em>x = 100×66/60</em>
<em>= 6600/60</em>
<em>= $ 110</em>

Kevin linear function is y = 3x + 1 while Jill function is y = 3x - 1
<h3>
Linear equation</h3>
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the rate of change (slope) and b is the y intercept.
Using the points (0, 1) and (2, 7), hence for Kevin:
y - 1 = [(7 - 1)/(2 - 0)](x - 0)
y = 3x + 1
Jill’s function has a y-intercept that is 2 less than the y-intercept, hence b = 1 - 2 = -1
Jill function is:
y = 3x - 1
Kevin linear function is y = 3x + 1 while Jill function is y = 3x - 1
