18 = 1a + 2b
That’s the equation for it
Answer:
2 per balloon
Step-by-step explanation:
Dozen = 12
Answer:
3/4
Step-by-step explanation:
First of all, we need to calculate the slope of the line shown. This can be computed as:
where
is the increment along the y-direction
is the increment along the x-direction
We can choose the following two points to calculate the slope of the line shown:
(-3,2) and (0,-2)
And so, the slope of the line shown is
Two lines are said to be perpendicular if the slope of the first line is the negative reciprocal of the slope of the second line:
Using 
, we find that a line perpendicular to the line shown should have a slope of
Answer:
a. 4/7
e. 3/4
Step-by-step explanation:
For each part of the question, count the dots that meet the first requirement, and count the dots that meet the "fraction of ..." requirement. The desired fraction is the ratio of these numbers. In the answers above, we have reduced the fractions to lowest terms, but the question does not seem to require that.
__
a. The desired fraction is ...
(dots in the triangle)/(all dots) = 16/28 = 4/7
__
e. (dots in the rectangle not in the circle)/(dots in the rectangle) = 9/12 = 3/4
Answer:
A
Step-by-step explanation:
The Y Intercept is for sure going to be 2 so we can eliminate answer choices B and D
The data shows a negative linear association so we can eliminate answer choice C
Therefore the answer is A
