Julio says, "If you subtract 13 from my number and multiply the difference by -3, the result is -54 ." What is Julios's num

Alchen [17]

Answer:Julios's number is 31

suppose: Julios's number is x

because Julio says, "If you subtract 13 from my number and multiply the difference by -3, the result is -54 "

=> we have: (x - 13).(-3) = -54

<=> x - 13 = (-54):(-3) = 18

<=> x = 18 + 13 = 31

<=> x = 31

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:

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