Assume xy = k; so k = 8*1.55 = 12.4
so x = 12.4/-0.62 = -20
Answer:
The answer is D) 60
Step-by-step explanation:
1st, you have to pick two whole ordered pair points
2nd, you have to use the formula: <u>Y2 - Y1</u>
X2 - X1
3rd, if it has to be simplified, then simplify
4th, you have an answer...
I found two whole ordered pairs which are (2,120) & (4,240).
- 2 represents X1
- 120 represents Y1
- 4 represents X2
- 240 represents Y2
<u>Y2 - Y1</u>
X2 - X1
<u>240 -120</u>
4 - 2
= <u>120</u>
2
Simplify... Divide both 120 &2 by 2 to get this: <u>60</u>
1
= 60
To identify the slope of the equation given, it would be helpful to write it in the slope-intercept form. It is expressed as y = mx + b where m is the slope. We write it as follows:
<span>27y=3x-54
y = 3x/27 - 54/27
y = x/9 - 2
Therefore, the slope is 1/9. Hope this answers the question. Have a nice day.</span>
Coordinate points:-4,15
you got to combine like terms and subtract
Answer:
7 or -9, dependent on if 2y is or is not negative
Step-by-step explanation:
If 2y is NOT negative
2(4)-1=i
8-1=i
i=7
If 2y IS negative
-2(4)-1=i
-8-1=i
i=-9
