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:
x=2
Step-by-step explanation:
To solve, we need to isolate the variable (x)
To do this, we must get all the variables to one side of the equation, and all the numbers to the other
3x+3= -2x+13
Add 2x to both sides to "reverse" the subtraction
5x+3=13
Subtract 3 from both sides to "reverse" the addition
5x=10
Divide both sides by 5 to "reverse" the multiplication
x=2
The correct answer is 12:16 P.M.
<h3>How to find when did Deb finish eating lunch ?</h3>
According to the problem,
- Deb started doing yard work at 9:52 A.M.
- After working for 1 hour and 48 minutes, she stopped to have lunch.
- It took her 36 minutes to eat lunch.
∴ Time at which Dev finishes her lunch =
9:52 A.M. + ( 1 hour and 48 minutes + 36 minutes )
= 11:40 A.M. + 36 minutes = 12 : 16 P.M.
∴ Deb finish eating lunch at 12:16 P.M.
