The correct answer would be

In order to solve for this you must first get the equation equal to 0.
<span>x^2=-5x-3 ----> add 5x to both sides.
x^2 + 5x = -3 ----> add 3 to both sides.
x^2 + 5x + 3 = 0
Now knowing this we can use the coefficients of each one in descending order of power as a, b and c.
a = 1 (because it is the coefficient to x^2)
b = 5</span> (because it is the coefficient to x)
c = 3 (because it is the end number)
Now we can plug these values into the quadratic equation.



And those would be your two answers.
Answer:
19, 21, and 23.
Step-by-step explanation:
Answer:
Here is a similar question attached with.
Option (b) that is 2005 is the right choice.
Step-by-step explanation:
Given:
An equation in slope intercept form.
Where
= number of years
Comparing from the standard slope intercept form.

y-intercept value
According to the question the predicted winning speed
mph
Plugging the value of
in slope intercept form, we will calculate the
(number of years) and then we will add this with
.
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
Finally the year would be
So in year 2005 the winning speed is predicted to be 7.16 mph.
I think it’s 337.5 .………………
Since it says don't switch the variables so this is the answer
