Answer:
y= -3x + 8
Step-by-step explanation:
Put -2x + 6y = -4 into slope-interceltp form
Take the negative reciprocal of the slope.
Use this reciprocal in point-slope form
and you have,
= y= -3x + 8
<em>(EDITED)</em> Steps:
2x+6y = -4
6y=2x - 4
y= 1/3x + 2/3
if two lines are perpendicular,
m1 * m2 + -1
1/3 * m2 = -1
m2 = -3
the line perpendicular to this line is
y = -3x + k ; k ∈ R
the line passes through the point (5,-7)
so,
-7 = -3. (5) +k
-7 = -15 + k
k = 8
∴the equation of a line that passes through the point (5,-7) and is perpendicular to the line -2x+6y=-4 is
y= -3x + 8
Hope this helps, have a nice day/night! :D
Answer:
There will be 213 songs in each group.
Step-by-step explanation:
Suppose, the number of songs in each group is 
As he has 4 different groups of songs, so the t<u>otal number of songs in all 4 groups</u> will be: 
Given that, the mp3 player has a <u>total of 852 songs</u>. So, the equation will be........

So, there will be 213 songs in each group.
Answer:
4f + 6g -5
Step-by-step explanation:
4f - 3 +2g- - 4g + 2
4f - 3+ 2g + 4g - 2
4f -3-2 +2g +4g
4f -5 + 6g
4f + 6g -5
Answer:
triangle with two equal sides.The angles opposite the equal sides are also equal.
Step-by-step explanation:
Let y= years ago when dad's age was 4 times son's age
60-y=4(30-y)
60-y=120-4y
-y+4y=120-60
3y=60
y=60/3
y= 20 years ago
Then 30-20= 10 yrs. old, the boys age when his dad was 40 years old.
