Answer:
y= -2x
Step-by-step explanation:
To find the slope, convert the standard form of the equation into slope intercept form, y=mx+b.
5x-10y=-12
-10y=-5x-12
y=1/2 x + 1.2
The slope is 1/2 and the slope of the new line will be -2 because the negative reciprocal create a perpendicular line. Use the point-slope form to write the equation, then simplify and convert into the slope intercept form.
(y-8)=-2(x--4)
y-8=-2(x+4)
y-8=-2x -8
y= -2x +0
Hey there! :)
Answer:
x = -4.
Step-by-step explanation:
We can write an algebraic equation to express this situation.
Let 'x' represent a number:
4(2x + 6) = -8.
Begin by dividing both sides by 4:
2x + 6 = -2
Subtract 6 from both sides:
2x + 6 - 6 = -2 - 6
2x = -8
Divide 2 from both sides:
2x/2 = -8/2
x = -4.
1.
Let w be the number of weeks it takes for Konrad to have more than $72.
The equation we can derive is 57 + 3w > 72.
Then solve:
57 + 3w > 72
3w > 15
w > 5
Then w must be 6, which is the next number greater than 5.
2.
Let w be the number of weeks it takes Omar to have enough money for the car.
The equation we can derive is 1800 + 35w 2150.
Then solve:
1800 + 35w 2150
35w 350
w 10
Then w must be 10.
Steps to solve:
y + 8 = -11
~Subtract 8 to both sides
y = -19
Best of Luck!
