Answer:
807.21
Step-by-step explanation:
for the 1 % decrease
1/100 × 784 = 7.84
784 - 7.84 = 776.16
then 4% increase
4/100 × 776.16 = 31.0464
776.16 + 31.0464= 807.2064
in 2 Decimal places
807.21
Answer:
The equation of the perpendicular line would be y = -1/2x - 1
Step-by-step explanation:
In order to find this line, we must first find the slope of the original line. We do this by solving for y.
-4x + 2y = 2
2y = 4x + 2
y = 2x + 1
This shows us a slope of 2. TO find the perpendicular slope, we use the opposite and reciprocal. This means we negative 2 to get -2 and then we flip it to get -1/2. Now that we have this, we can use the slope and the point in point-slope form to get the equation.
y - y1 = m(x - x1)
y + 2 = -1/2(x - 2)
y + 2 = -1/2x + 1
y = -1/2x - 1
Step-by-step explanation:
m(x) = x+3
y = x+3
=> x = y-3
m`¹(x) = x-3
