Answer:

Today, gasoline prices are $3.44 per gallon.

One year ago, gasoline prices were $3.75 per gallon.

Part A

=> The change is: 3.44 - 3.75 = -0.31

=> The percent change is: -0.31/3.75 = -0.083 = -8.3% of last year's price.

Part B

You calculate the change by subtract the current year's price to the last year's price. If the change is negative, it means the price is down. If the change is positive, it means the price is up.

Next, you divide last year's price by the change to get the percent change.

This negative percent change (-P) can be seen as the fact that last year you bought an amount of gallon which cost 100$, this year, you buy the same amount, you have a discount which is equal to P dollar.

Hope this helps!

Percent change in price =
new price - old price / old price =

3.44 - 3.75 / 3.75 = -8.267%


Answer: Prices of gasoline has reduced by 8.3% since last year.

It means that if you bought $100 worth of gasoline last year, you will have to pay only $91.7 for the same amount of gasoline now.

Which values of x are solutions to the inequality?
Blababa [14]

Answer:

B. x=-210

D. x=-201

Step-by-step explanation:

Given:

The inequality for 'x' is given as:

x

The above inequality tells us that, the value of the variable 'x' is less than -200.

-200 is a negative number. So, for a negative number, the larger the value of the number, the smaller the number is.

Example: -2 is less than -1 although 2 has a greater magnitude than 1.

Therefore, the numbers that are less than -200 are -210 and -201.

So, the values of 'x' that satisfy the given inequality are -201 and -210

Thus, the correct options are (B) and (D).

-Dominant- [34]
6t + 5j= 34
2t + 3j = 16

12t + 10 j = 68
12t + 18j = 96
-8j = -28
j = 3.5

jelly beans= 3.5 and trail mix = 2.75

Graph the inequality in the coordinate plane:<br><br> x&lt;-3
tensa zangetsu [6.8K]

Answer:

Graph of the inequality x< -3 as shown below in the figure.

Step-by-step explanation:

Given the inequality: x < -3

Graph of this inequality as shown below in the figure.

All the points that are lie in the shaded area satisfy the equation x < -3 or

In other words, we can say that x can take any value less than -3 .

x ≠ -3 or any number that is greater than -3.

Since there is a strict inequality i.e x < -3 , the points that lie on the line x = -3 does not satisfy the equation.

Therefore, the dotted line is marked at x = -3
