Ann has 20$ . She bought 2 notebooks. How much does they costed ?
2x=20
x= 20/2
x=10
y - y₁ = m(x - x₁)
y - (-2) = ¹/₂(x - 4)
y + 2 = ¹/₂(x) - ¹/₂(4)
y + 2 = ¹/₂x - 2
- 2 - 2
y = ¹/₂x - 4
Your answer would be A. positive linear association.
If we break this phrase down, we first get "positive", which we can see is true here as the graph is ascending towards the top right, that is, going upwards and 'forwards'. This is how we recognise lines with positive slopes, such as 3x or (1/2)x.
The word "linear" means a straight line, you can sort of see the word "line" in it, and so this is also true as the trend line is straight.
I hope this helps!
Lin's tour costs 5*14 +50 = 70 +50 = 120. Max's tour costs 120.
Neither tour costs less. Both have the same cost.
Answer:
y ÷ 6.
Step-by-step explanation:
An expression is a combination of a number(s) and a variable.
Here, we simply need to write the expression from the word problem in mathematical form.
"Number" is unknown.
Variables are used to represent an unknown value.
(The variable in this expression is y).
The word problem says a number y divided by 6.
This simply means: y ÷ 6.
