Answer:
3
Step-by-step explanation:
From the table, we know at least 2 ordered pairs. We can use the slope formula on any 2 ordered pairs on the table to get 3.
Answer:
Part a) Daniel's age is 2 years
Part b) Kevin's age is 8 years
Step-by-step explanation:
<u><em>The question is </em></u>
Part a) How old is Daniel?
Part b) How old is Kevin?
Let
x ----> Kevin's age
y ----> Daniel's age
we know that
-----> equation A
----> equation B
Equate equation A and equation B

solve for y



therefore
Daniel's age is 2 years
<em>Find the value of x</em>
substitute the value of y in any of the two equations


therefore
Kevin's age is 8 years
2x-5= 7
Add 5 on both sides
2x= 12
Divide by 2
X= 6
The answer is x = 6
Let us first define x to be the number of hours of riding lessons she can take.
X = Hours of lessons
Now, she has $200, she needs to pay $20 for grooming supplies, and the lessons cost $30 an hour. We to find the maximum amount of hours of lessons she can take, so in other words, we want to make her broke. To do this, we first convert the words into an equation:
200 - 20 - 30x = 0
Simplifying, we get
180 = 30x
x=6
