1) a. 15% decrease
2) a. $79.20
3) b. 14.3% increase
4) a. $4.68
#1 explanation:
1435 - 1220 = 215
215/1435 = 0.1498
0.1498 x 100 = 14.98 = 15%
#2 explanation:
220 x 0.6 = 132
220-132=88
88 x 0.1 = 8.8
88-8.8 = 79.2 $
#3 explanation:
32-28=4
4/28=0.1428
0.1428 x 100 = 14.28 = 14.3%
#4 explanation:
275 x 0.15 = 41.25
275-41.25 = 233.75
233.75 x 0.02 = 4.675 = 4.68 $
Answer:
A. a line segment
Step-by-step explanation:
- a ray is directing in one dxn, and has no end point
- a plane is a closed, so more than 2 points
- a vertex is a single point itself
1.IN SOLIDS THERES NO SPACE FOR PARTICLES TO MOVE AROUND
2.LIQUID THERES A LITTLE BIT OF SPACE TO MOVE FREELY
3. GAS HAS ALL SPACES TO MOVE AROUND SINCE ITS NOT PUT TOGETHER

3 +dy/dx = 0+ 2x²ydy/dx + 2xy²
dy/dx - 2x²ydy/dx = 2xy² -3
(1 - 2x²y) dy/dx = (2xy²-3)/(1-2x²y)
Answer:
y = x + 5
Step-by-step explanation:
Perpendicularity: Slope is the opposite reciprocal. In this case with it being -1 aka -1/1, the slope will be 1 aka 1/1
Find the opposite reciprocal of the slope
m = -1 = -1/1
so,
m⊥ = 1 as the opposite reciprocal is 1/1
2 - Plug the new slope into y = mx + b
y = mx + b
y = 1x + b
y = x + b
3 - Plug the point values in replacing x and y to get alone and solve for the y intercept, b.
y = x + b
-4 = -9 + b
+9 +9
5 = b
4 - Plug into the values into y = mx + b all together
y = mx + b
y = 1x + 5
y = x + 5
Hope this helps :)
