complete the equation of the line whose slope is -2 and y-intercept is (0,-8)

y= ????​

Answers

Answer:

y = -2x - 8

Step-by-step explanation:

Slope-intercept form is y = mx + b. Slope is m, and y-intercept is b. To do this, we substitute -2 for m and -8 for b. When we do this, we get y = -2x + -8. We can simplify this to y = -2x - 8.

round 427963 to the nearest thousand

Answers

Answer:

428,000

Step-by-step explanation:

427,963

If the number behind what number you're trying to round is greater than 4 then the number you're rounding goes up once while everything behind it goes to zero. If it's below 5 than the it well stay the same. Ex. Round nearest tenth--> 14--->10  instead of it going up to 20 it stays 10.

427,963

      ^

This number is higher than 4 so the number in front or the thousand mark goes up a number.

428,000

Answer:

x = 5

Step-by-step explanation:

The opposite sides of a parallelogram must be parallel to each other, and this is shown by the equivalent opposite interior angles on each side of the bisector.

Since the opposite sides of a parallelogram are parallel, they must be of equal length (this is one of the fundamental properties of a parallelogram).

Therefore, we can set (18x - 5) and (16x + 5) equal to each other in an equation and solve for x.

18x - 5 = 16x + 5

Subtract 16x from both sides.

2x - 5 = 5

Add 5 to both sides.

2x = 10

Divide both sides by 2.

x = 5

The value of 5 for x must make ABCD a parallelogram.
