PLEASE HELP!!!Which equation goes through the point (-7, 3) and is parallel to y = −8x + 1?

Mathematics

Blizzard [7]3 years ago

Answer:

  y - 3 = -8(x + 7)

Step-by-step explanation:

The equation of a line with slope m through point (h, k) is ...

  y -k = m(x -h)

__

The slope you want is m = -8, which is the slope of the given line.* The given point is (h, k) = (-7, 3), so the equation you're looking for is ...

  y - 3 = -8(x -(-7))

The expression inside parentheses can be simplified so you have ...

  y - 3 = -8(x + 7)

_____

* The given line is in "slope-intercept" form, which is y = mx + b. Matching this pattern to the given equation, you see that m=-8. Parallel lines have equal slope, so -8 is the slope of the line you're writing the equation for.

What is the probability that out of 125 babies born, at least 70 will be girls?
mote1985 [20]

Answer:

Well just looking at the choices can lead you to the answer right away.

Well since the probability of boys and girls are equal, its 50/50. And since 125 in half well about is about 60-62 and the minimum amount of girls has to be 70. It can’t be higher then half and the choices remain to less then half not including 50%. So that eliminates all 3 choices except B.

y = 3 is the line of reflection

Under a reflection in a line, corresponding points of the original and it's image should be equidistant from the line of reflection

y = 3 is the horizontal line passing through all the points with a y-coordinate of 3

A is 1 unit above and A' is 1 unit below the line

B is 3 units above and B' is 3 units below

C is 1 unit below and C' is 1 unit above

D is 1 unit below and D' is 1 unit above

The vertices of the figure and the image are all equidistant from y = 3
