Set up a system of equations:

x + y = 0.6
x - y = 7.2

You can solve using elimination. Add the two equations together:

2x + 0y = 7.8
2x = 7.8
x = 3.9

Then plug the number back into either of the two original equations to solve for y:

3.9 + y = 0.6
y = -3.3

The two numbers are 3.9 and -3.3

Write an equation of the line that passes through the point(-6,-9) with slope -5
LUCKY_DIMON [66]

Answer:

  y = -5(x +6) -9

Step-by-step explanation:

The point-slope form of the equation for a line can be written as ...

  y = m(x -h) +k

for a line with slope m through point (h, k).

You have m=-5 and (h, k) = (-6, -9). Filling in these values gives ...

  y = -5(x -(-6)) -9

Simplifying a bit, you get ...

  y = -5(x +6) -9

If you were to sort 0.8, 1/4, .08, 8/10, what would be the order they would be in (smallest to biggest)?
weqwewe [10]

Answer:


Step-by-step explanation:

0.8 = 8/10 = 80/100

1/4 = 25/100

0.08 = 8/100

8/10 = 80/100

Smallest: .08

In between smallest and largest: 1/4

Largest: 0.8 and 8/10, and they are equal
