Answer:
This is proportional
Step-by-step explanation:
Your slope is 2 each time. To find slop you do rise/run. go to a dot and go up 2 and over 1. Simplify that and you get a slope of 2. Keep doing that for each point then you can determine if it is proportional or not. In this case it is. Hope this helps :)
Answer: (C) 1
<u>Step-by-step explanation:</u>
The question is asking which y-value are not represented in the graph. IN other words, they are asking for which values are not included in the range.
You can do this by graphing the equations:
y = x + 2 for x ≥ 0 has a y-intercept of +2 with y-values increasing
- <em>Note: +2 is included so has an closed dot</em>
y = x - 2 for x < 0 has a y-intercept of -2 with y-values decreasing
- <em>Note: -2 is not included so has an open dot</em>
Therefore, there are no y-values between +2 and -2 (including -2). The only option provided between these values is 1, which is option C.
I think you guys are using a^2 + b^2 = c^2
the equation would be
x^2 + 2x^2 = 6^2
X^2 + 4x = 0
x^2 + 4x + 4 = 0 + 4
(x + 2)^2 = 4
Answer: b) x = 6 and total line is 52
c) x = 5.5 and total line is 20
Step-by-step explanation:
b) (x+20) = (5x-4)
4x = 24
x = 6
Line (x+20) = 26
Line (5x-4) = 26
Total line = 52
c) (4x-12) = (-2x+21)
6x = 33
x = 5.5
Line (4x+12) = 10.0
Line (-2x+21) = 10.0
Total line = 20
