Solve the following system by elimination. 24.
-18-8

9x + 2y

A. (-9, -8)
B. (8-8)
C. (-9, -3)
D. 2, -8)

Step-by-step explanation:

The equation is nor properly written. Let the equations be;

9x+2y = -8 1

9x - 3x = 7 2

Subtract 1 from 2;

(9x-9x) - (2y-(-3y)) = -8-7

0 - 5y = -15

-5y = -15

y = -15/-5

y = 3

Substitute y = 3 into 2;

From 2; 9x - 3x = 7 .

9x - 3(3) = 7

9x - 9 = 7

9x = 16

x = 16/9

Hence the solution (x, y) is (16/9, 5)

Note that the equations was assumed. The same method an be applied to similar problem.

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
