Solve the system of linear equations. 3x−2y=1 9x−6y=3

1 answer:

8 0

Get the y by itself

-2y= -3x + 1

Divide -2 to everything

y= 3/2x - 1/2

Other equation (get y by itself)

-6y= -9x + 3
y=3/2x - 1/2

Use substitution

3/2x-1/2=3/2-1/2

0=0

All real numbers (any value of x makes the equation true)

a basket of laundry is being separated. Divide 48 pieces of clothing into 2 groups so the ratio is 1 to 3

Liula [17]

Group 1: Group 2

1 : 3

Total amount of splits = 1 + 3 = 4

48/4 = 12

12 : 12+12+12

12 : 36

12 in pile 1 and 36 in pile 2.

= 1.6 - 1.2
= 0.4

1/2 k when k =2/3
1/2 (2/3)
= 1/3

What is the slope intercept form of the perpendicular line to the line with (-2,7), (0,1) and (2,-5) points

MAVERICK [17]

Answer:

Step-by-step explanation:

Slope of line through the three points is -3.

Slope of any perpendicular through the line is ⅓.

(0,1) is one of the points on the line, so the y-intercept is 1.

Slope-intercept equation for line of slope ⅓ and y-intercept 1:

y = ⅓x+1
