A man spend 2500 per month for four months and runs into debts. He then reduces his expenses 1750 per month and just clears of h

nikdorinn [45]

Answer:

Step-by-step explanation:

Let the income per month be S

Total income in 8 months = 8 S .

Total expenses in four months = 2500 x 4 = 10000

Total expenses in next four months = 1750 x 4 = 7000

Total expenses = 17000

According to question

Total income in 8 months = Total expenses

8 S = 17000

S = 2125 per month .

write an equation of a line that is perpendicular to the given line and that passes through the given point (4,-6); m=3/5

tresset_1 [31]

Answer:

$y=-\frac{5}{3} x-\frac{42}{5}$

Step-by-step explanation:

Given the slope and another point, simply plug them into the point-slope formula to find your y-intercept.

$y-y1=m(x-x1)\\y-(-6)=\frac{3}{5} (x-4)\\y+6=\frac{3}{5} x-\frac{12}{5} \\y=\frac{3}{5} x-\frac{42}{5}$

Now that we've found your y-intercept, we have the original equation. To find the perpendicular equation, you need the opposite reciprocal of your slope.

To find the 'opposite,' change your slope's sign. Since your slope is positive $\frac{3}{5}$ , the opposite is $-\frac{3}{5}$ .

To find the 'reciprocal,' flip your fraction. This will make your slope $-\frac{5}{3}$ .

Your final equation is:

$y=-\frac{5}{3} x-\frac{42}{5}$
