Answer:
D) R’(2,3); S’(7,3); T’(5,8); U’(0,8)
Step-by-step explanation:
The last one. If you reflect it over the x-axis, it moves from quadrant IV to quadrant I. Everything in quadrant I is positive, and the last one is the only one that has all x and y values positive.
Answer:
-9/11
Step-by-step explanation:
The slope of the line is given by
m = (y2-y1)/(x2-x1)
= (9-0)/(-3-8)
= 9/-11
= -9/11
Answer:
Non Proportional
Step-by-step explanation:
Make a proportion:
For example say you want to test out how many bottles of water you can buy for $10
Proportion:
4 - 6
10 - ?
Solve: 10×6÷4=15
So technically, you could only get 15 bottles for $10. Therefore, this is a non proportional problem.
Let s and g represents the numbers of suits and gowns produced.
The number of zippers used is 2s+g.
The number of buttons used is 5s+8g.
In order to use all of the available zippers and buttons, we must have ...
- 2s + g = 171
- 5s + 8g = 576
Cramer's rule tells you the solution to the system
Is given by
- x = (bf-ey)/(bd-ea)
- y = (cd-fa)/(bd-ea)
Using this rule on the equations for zippers and buttons, we have
... s = (1·576 -8·171)/(1·5 -8·2) = -792/-11 = 72
... g = (171·5 -2·576)/-11 = -297/-11 = 27
72 suits and 27 gowns can be made from available zippers and buttons.
