frez [133]

9514 1404 393

Answer:

  A'(-4, -4), B'(6, -4), parallel

Step-by-step explanation:

The dilation factor multiplies each of the coordinate values. The line that was y=-2 becomes the line y=-4, a parallel horizontal line.

What is the y intercept of a line that passes through (1,-7) and (5,-25). How do I find it.
LUCKY_DIMON [66]

Answer:

y- intercept = - 2.5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (1, - 7) and (x₂, y₂ ) = (5, - 25)

m = \frac{-25+7}{5-1} = \frac{-18}{4} = - 4.5 , then

y = - 4.5x + c

To find c substitute either of the 2 points into the equation

Using (1, - 7), then

- 7 = - 4.5 + c ⇒ c = - 7 + 4.5 = - 2.5

y- intercept c = - 2.5

A large oak tree has 2 × 10 ^ 5 Leaves during its lifespan a large forest can have About 5 × 10 ^ 3 oak trees approximately how
irga5000 [103]

Answer:

1,000,000,000 leaves or 1 x 10^9 leaves

Step-by-step explanation:

One large oak tree has 2 x 10^5 leaves, so we can make that number to 200000

There are 5 x 10^3 oak trees in a forest, we can make that number to 5000

Since we want to find out how many leaves are in the whole forest we multiply: 200000 x 5000 = 1,000,000,000

So approximately there are 1 billion leaves or 1 x 10^9 leaves

If ABC=DEF and MNO=PQR, then ABC=PQR by the transitive property.
zavuch27 [327]

Answer:

B. False

Step-by-step explanation:

There is not enough information to make that conclusion. The two statements are completely unrelated, so the transitive property cannot be used. None of the given statements say that ABC is congruent to MNO or PQR. That means that nothing can be assumed about DEF. To use the transitive property you would need proof that ABC=MNO or ABC=PQR. But neither of those statements are there so the answer is false.
