Answer:
Victor should buy Legend because it has a better unit rate
<em></em>
Step-by-step explanation:
See attachment for complete question.
To determine which car has more gas efficiency, we have to calculate the slope of each car.
Vehicle 1: Legend
Take any two corresponding points from the table
The slope is then calculated using;
<em>This implies that this vehicle (legend) travels 18 miles per gallon of gas</em>
Vehicle 2: Supreme
Take any two corresponding points from the graph
The slope is then calculated using;
This implies that this vehicle (supreme) travels 16.7 miles per gallon of gas
<em>Base on the calculations above, Victor should buy Legend because it has a better unit rate</em>
Answer:
The discriminant is -7
Step-by-step explanation:
The discriminant of a quadratic function/equation(ax^2+bx+c = 0) is calculated as:
Here
b is the co-efficient of x
a is the co-efficient of x^2
and c is the constant
Given equation is:
Here
a = -2
b = 5
c = -4
Putting the values in the formula for discriminant
As the discriminant is negative, the equation has no real solution.
Hence,
The discriminant is -7
