To solve for x in an inequality is very similar to solving for x in an equation since for both you would need to isolate x.
step 1) -2x-4>8 add the 4 over to move any constants over to the +4 +4 other side.
-2x> 12
step 2) x< -6 Divide out the -2 to isolate x, however, keep in mind, when you divide or multiply over any negative number, you must also remember to flip the inquality sign.
Answer: x<-6
Answer:
{3,-1}
Step-by-step explanation:
m^2 -2m -3=0
What 2 numbers multiply to -3 and add to negative 2
-3* 1 = -3
-3 +1 =-2
(m-3) (m+1) =0
Using the zero product property
m-3 = 0 m+1 =0
m=3 m=-1
{3,-1}
Answer:
No.
Step-by-step explanation:
No, y=x²-6 is not a linear function.
This is because all linear functions have the highest exponent of 1. Anything equation that has a variable raised to a power other than 1 is not linear.
The equation provided as the highest exponent of 2. Thus, it's not linear.
From the provided graph, we can also see that this is quadratic instead of linear. The graph is a parabola instead of a line.
Percentage by which the average value of mid sized car decreases each year = 8%
Retail value of a car today = v dollars
Amount of decrease in the value of the car after 1 year = (8/100) * v
= 2v/25 dollars
Then
The equation that represents the value of the car after 1 year = v - (2v/25) dollars
= (25v - 2v)/25 dollars
= 23v/25 dollars
So following this expression the value of the mid sized car can be easily determined after 1 year. I hope this is the answer you were looking for and the procedure is also clear to you.
