Answer:
Congruent figures are the same size and the same shape.
We need an image to find which polygons are congruent. Could you give one and then i'll solve it?
Answer:
2) 6
4) 9
Step-by-step explanation:
"They have different slopes but the same y-intercept, so they have one solution" is the statement which best describes the two lines.
Answer: Option D
<u>Step-by-step explanation:</u>
Given equations:


As we know that the slope intercept form of a line is
y = m x + c
So, from equation 1 and equation 2 we can see that


So, from the above expressions, we can say that both lines have different slopes but have same y – intercept with one common solution when x = 0.
The linear function that models the total cost for x deliveries is:

-------------------
A linear function has the following format:

In which
- m is the slope, that is, the rate of change.
- b is the y-intercept, that is, the value of y when x = 0.
In this problem:
- Fixed cost of $9 per month,
. - Cost of $2 for each delivery, thus
.
The function for the <u>total cost for x deliveries is:</u>
