X=9

You add 3 to both sides which leaves you with 2x=18 and then divide by two and that gives you x=9

Maria has 3 ceramic cats. She plans to buy some more. Write an equation in the form of y = x + b, b≠ 0 (b is not equal to 0) tha

Snezhnost [94]

Answer: y = 3+b

Step-by-step explanation:

Hi, to answer this question we have to write an equation:

y = x + b

Where:

y = total number of ceramic cats

x = actual number of ceramic cats

b=new ceramic cats bought

Replacing with the value given:

y = 3+b

Where y is the dependant variable and b the independent variable.

Victor was having a hard time deciding which new vehicle he should buy. He decided to make the final decision based on the gas e

Amanda [17]

Answer:

Victor should buy Legend because it has a better unit rate

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

$(x_1,y_1) = (4,72)$

$(x_2,y_2) = (12,216)$

The slope is then calculated using;

$m = \frac{y_2 - y_1}{x_2 - x_1}$

$m = \frac{216 - 72}{12 - 4}$

$m = \frac{144}{8}$

$m = 18$

This implies that this vehicle (legend) travels 18 miles per gallon of gas

Vehicle 2: Supreme

Take any two corresponding points from the graph

$(x_1,y_1) = (0,0)$

$(x_2,y_2) = (15,250)$

The slope is then calculated using;

$m = \frac{y_2 - y_1}{x_2 - x_1}$

$m = \frac{250 - 0}{15 - 0}$

$m = \frac{250}{15}$

$m = 16.7$

This implies that this vehicle (supreme) travels 16.7 miles per gallon of gas

Base on the calculations above, Victor should buy Legend because it has a better unit rate
