Explanation:

A. When you examine the values in the table, you see the y-value is not proportional to the x-value. That is, 20/1 ≠ 26/2. However, you do notice that the y-values increase by 6 when the x-values increase by 1. <em>The ratio of these increases is the slope of the graph of the relation between y and x</em>.

Since the slope is 6, we might expect a value of 6×1 = 6 for x=1. However, the y-value for x=1 is 20, which is 14 more than what might be predicted by the slope. <em>This added extra is the y-intercept on the graph of the relation</em>.

The slope is 6 and the y-intercept is 14.

B. The slope is (26-20)/(2-1) = 6.

C. For x=1, the slope-intercept equation tells us ...

y = 6x +b

20 = 6·1 + b . . . . . . . . . . substitute (x, y) = (1, 20)

20 -6 = 14 = b . . . . . . . . subtract 6 to find b

The difference of x and 18 is greater than or equal to -12<br><br>its a inequality question

slavikrds [6]

Writing the word problem as an equation you get:

x - 18 ≥ -12

Now to solve for x:

Add 18 to both sides of the inequality:

x ≥ -12 + 18

Simplify:

x ≥ 6

If an object has a Mass of 11g and a volume fo 13mil, what is its density?

tino4ka555 [31]

Step-by-step explanation:

Mass (m) = 11 g

volume (v) = 13 ml

density (d) = ?

We know density is defined as mass per unit volume so

d = m / v

= 11 / 13

= 0.85 g/ml

Density (d) = 0.85 g/ml

The graph that best represent the relationship between time and cost is option A as it is a proportional graph

<h3>How to know the graph that represent the relationship between time and number of team?</h3>

Each week 6 teams register to participate.

Therefore, for every week 6 team register to participate in the competition.

This simply implies as time increases , the number of participant in the competition also increase.

Therefore, the equation that can be use to represent this situation is as follows:

y = 6x

where

y = number of team registered
x = time in weeks.

Hence, the graph that best represent the relationship between time and cost is option A as it is a proportional graph. The registered team increases as the time in weeks increase.
