Solution
Given the question in the image, the following are the solution steps to answer the question.
STEP 1: Write the formula for slope
STEP 2: Pick two points
STEP 3: Find the unit price per cup
Since 4 cups cost $5, one cup will cost
Therefore, the answer is $1.25
Answer:
between 222 and 223 days
Step-by-step explanation:
This relation includes the point (0, 2).
A proportional relation must include the point (0, 0).
This is not proportional, but it may be linear.
Points: (0, 2), (2, 20)
y = mx + b
20 = (20 - 2)/(2 - 0) × 2 + b
20 = 18/2 × 2 + b
b = 2
y = 18x + 2
When 4000 people know, y = 4000.
y = 18x + 2
4000 = 18x + 2
3998 = 18x
x = 3998/18
x = 222.111...
Answer: between 222 and 223 days
Here is what the answer to your question is:
7x10x1=70
Replace a with 4 and b with -12
3(4) + -12/4 + 4(4) = 16+-12/4+4*4 = 29
