Sign changing means that each value went from positive to negative.
Assuming A is a 180 degree rotation around the origin, the answer would be A.
B doesn't change the sign for neither x nor y.
C changes the sign for y, but not x.
D changes the sign for x, but not y.
For 15 its just the shape, if you draw a shape based on the dots, compare them. Like left one is a bit taller and wider.
16: for left one median is 8 i think. Right one is 9.5 i think
17: for left one, 13 is an outlier, for right one, 11.5 is outliner. You just write the beginning and ends including and not including those outliers.
18: people in group A were kids and people in group B were adults because their shoe sizes are much higher.
Answer:
Step-by-step explanation:
So we want to find an equation of a line passing through (-8,2) with a slope of 4/3.
To do so, we can use the point-slope form. This is:
So, substitute (-8,2) for x₁ and y₁, and let m be 4/3:
Distribute the right:
Add 2 to both sides. Note that 2 can be written as 6/3. Thus:
Simplify:
And this is our equation :)
A candy store sells 8 pound bags of mixed almonds and cashews. If c pounds of cashews are in a bag,...
c=1 was already given as described. The store sells pound bags.
The rest of the description and question seem not to match. Maybe each bag contains 8 pounds of the two nuts. Eight pounds and some of this is of cashews. Now, c is how many pounds of cashews in one bag.
-
p=2.59%2Ac%2B1.72%288-c%29
You want to know the quantity of cashews if p=18.11 dollars per bag.
2.59c%2B1.72%2A8-1.72c=p
2.59c-1.72c=p-1.72%2A8
%282.59-1.72%29c=p-1.72%2A8
0.87c=p-13.76
