If 2x + y = 12 and x + 2y = -6, then find the value of 2x + 2y

1 answer:

3 0

2x + y = 12
2x = 12 - y

x + 2y = -6
2y = -6 - x

2x + 2y
12 - y + (-6) - x
12 + (- 6) - y - x
12 - 6 - y - x
6 - y - x

Answer: - x - y + 6

Line segment XY is a directed line segment beginning at point X(9, 2) and ending at point Y(-6, 2). Find the point Z on the line

lozanna [386]

Answer:

$(-\frac{3}{8},2)$

Step-by-step explanation:

Point Z divides XY into a 5:3 ratio, so Z is 5/3 of the way from X to Y. That ratio is k, found by writing the numerator of the ratio (5) over the sum of the numerator and the denominator (5 + 3 = 8). Our k value is 5/8. Now we will find the rise and run values which is the slope of this line segment:

$m=\frac{2-2}{-6-9} =\frac{0}{-15}$
