Answer:
In general, quadratic equations have two x-intercepts. But sometimes it happens that a quadratic eqution has one x-intercept or no interepts. That's why we should fully analyze this equation:
Given the following equation: y=3x^2 + 7 + m
If y=0, then:
3x^2 + 7 + m = 0 ⇒ x^2 = (-m-7)/3
Then
± 
Given that we can take the square root of a negative number, the only way this equation has two x-intercepts is if m<-7.
Summarizing:
The equation: y=3x^2 + 7 + m has two x-intercepts only if m is less than -7. If m equals -7, the equation has only one x-intercept, and finally, if m is greater than -7, the equation has NO x-intercepts.
Answer:
Step-by-step explanation:
The idea behind the standard deviation is to quantify the spread of a distribution by measuring how far the observations are from their mean. The standard deviation gives the average (or typical distance) between a data point and the mean.
The answer would be 362 miles
add the number of miles from day one and day two
Based on the information given, the value of the down payment will be $6936.
<h3>
Solving the percentage.</h3>
Based on the information given, the cost of the truck is $28900 and the down percentage given is 24%.
Therefore, the down payment that will be made will be:
= 24% × $28900
= 0.24 × $28900
= $6936
In conclusion, the correct option is $6936.
