One number is nine more than a second number. Four times the first is 6 less than 2 times the second. Find the numbers.

Masteriza [31]

9514 1404 393

Answer:

-12, -21

Step-by-step explanation:

Let x represent the first number. Then the second is x-9. The other relation is ...

4x = 2(x-9) -6

2x = -24 . . . . . subtract 2x, simplify

x = -12

x-9 = -21

The first number is -12; the second number is -21.

What is the perpendicular slope to 6/-3

IRISSAK [1]

Answer:

Perpendicular slope is $\frac{3}{6}$ or $\frac{1}{2}$ .

Step-by-step explanation:

Given:

Let the perpendicular slope be x.

The given slope is $\frac{6}{-3}$

For perpendicular slopes, the product of the slopes is equal to -1.

Therefore, $x\times \frac{6}{-3}=-1\\-\frac{6}{3}x=-1\\6x=3\\x=\frac{3}{6}=\frac{1}{2}$

Therefore, the perpendicular slope is $\frac{3}{6}$ or $\frac{1}{2}$ .
