Hi mate:
Here is your explanation......
Which of the following is perpendicular to 32=16y+64x
Possible Answers:
y=−x/4+7
y=4x+7
y=−4x+7
y=x+1/4
y=x/4+7
Correct answer:
y=x/4+7
Explanation:
Two lines are perpendicular if and only if their slopes are negative reciprocals. To find the slope, we must put the equation into slope-intercept form, y=mx+b, where m equals the slope of the line. We begin by subtracting 16y from each side, giving us 32−16y=64x. Next, we subtract 32 from each side, giving us −16y=64x−32. Finally, we divide each side by −16, giving us y=−4x+2. We can now see that the slope is −4. Therefore, any line perpendicular to 32=16y+64x must have a slope of 1/4. Of the equations above, only y=x/4+7 has a slope of 1/4.
Answer:
1/5
Step-by-step explanation: 4
"4 to 20" is in itself a ratio. This can be written as 4:20 or as -------
20
and this last result reduces to 1/5.
5x / 2 - 8 = 22
multipy through by 2:-
5x - 16 = 44
5x = 44 + 16 = 60
x = 12 Answer
You need to simplify the expression and then you will know what the y coordinates are. I’m not good at this But you just need to solve the equation to be able to get the same coordinates by themselves. It’s sorta like geometry and algebra mixed. But first simplify the equations and then that will really help you.
Have a great day!
