Answer:
Step-by-step explanation:
I think its B and K, they both have 2 sets of parallel lines and they have no congruent sides. Also they look similar. Sorry if this doesn't help.
The vocabulary terms have been matched to the correct definitions as follows;
- Direct variation: describes variation between proportional relationships
- Slope: a ratio describing vertical change to horizontal change of a linear relationship on a coordinate grid
- Rate of change: a number, k, that represents the unit rate used in a direct variation equation y = kx for comparing proportional relationships between two variables x and y found by using division
- Unit rate: a speed or rate of change where the denominator (or second quantity measured) in the ratio is 1
- Constant of proportionality: the ratio of vertical change to horizontal change rate of change
<h3>What are Mathematical Terms?</h3>
- Mathematical terms refer to phrases and words that define certain arithmetic standards.
- The above are the definitions of the mathematical terms. Direct variation, for instance, expresses the relationship between two variables, x, and y.
- The slope is often used after graphing and indicates the relationship of change between the vertical and horizontal axes.

x = 7
isolate x by dividing both sides by - 2
x =
= 7
Based on the information given, the number of bills will have to be between 13 and 28 every month.
<h3>
Solving equations</h3>
Let the number of bills be represented by x.
Therefore, the equation to solve the question will be:
2.25 + (0.10 × x) = 3.50
2.25 + 0.10x = 3.50
0.10x = 3.50 - 2.25
0.10x = 1.25
x = 1.25/0.10 = 12.5 = 13
Also, 2.25 + 0.10x = 5.00
0.10x = 5.00 - 2.25
0.10x = 2.75
x = 27.5 = 28
Therefore, the number of bills will be between 13 and 28 every month.
