Solution is x= -9.297 or -9.30 rounded and y= 5.6
It's a scalene triangle, a triangle where all of the sides are different lengths.
We are asked to prove or disprove the statement : <span>If a divides bc, then a divides b or a divides c. the statement is expressed as a / bc which is equal to a/b * (1/c). The statement is true since a truly is divided by b or a can be divided by c. Or is essential since a is not expressed as a^2 </span>
The cost would be the same for Justin and Bella if 500 checks are sold, costing about $200.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
Given the equation for Bella:
c = 0.1n + 150
Where C is the monthly cost for n checks.
For Justin:
1.2 = 3k
k = 0.4
C = 0.4n
To have the same cost:
0.1n + 150 = 0.4n
n = 500
c = 0.4(500) = 200
The cost would be the same for Justin and Bella if 500 checks are sold, costing about $200.

Answer:
7 and 8: these are both proportional relationships because they grow at a constant rate of change
9: for every 40 miles that the car travels, it uses 2 gallons of gas.
10: y= 20x
11: the graph would be steeper and have a greater rate of change. This car would be able to go farther on less fuel.
