The student is incorrect because if they were to reflect point A over the X-axis, this would mean they are moving it from its current quadrant to the one below. In that quadrant, the Y coordinate will be negative. So it couldn't possibly (6,3), because the 3 isn't negative.

Do y'all know the answers to these, they so confusing even if I look up videos on it plz help asap
Brrunno [24]
I'm not going to give you the answer, but I'm going to give really obvious hints to you.
Supplementary angles are when two angles add up to 180 degrees.
Complimentary is when two angles add up to 90 degrees.
I'm not sure how you find angles m<y and m<v, I can't even see the letter m on the attachment.
There are two angles that are adjacent to <GXF, and you are free to choose which ever ones you like: <FXE and <CXG

Find the value of k so that the graph of the equation has the given slope. y = 4kx−5; m = 12
olga nikolaevna [1]

Answer:

k = 3

Step-by-step explanation:

The slope-intercept equation of a str. line is y = mx + b.

In this particular case, m = 12, so we have     y = 12x + b

Comparing this to the given                           y = 4kx + b

we see that 12 must = 4k, and thus k = 3

An object is dropped from 39 ft below the tip of the pinnacle atop of 363 ft tall building. The height h of the object after t s
Ksenya-84 [330]

Answer:

4.5 seconds pass before reaching the ground

Step-by-step explanation:

The height of the object is given by the following equation:

h(t) = -16t^{2} + 324

How many seconds pass before reaching the ground

It hits the ground when h(t) = 0. So

h(t) = 0

-16t^{2} + 324 = 0

16t^{2} = 324

t^{2} = \frac{324}{16}

t = \pm \sqrt{\frac{324}{16}}

t = \pm 4.5

There are no negative instants of time, so only the positive answer interests to us.

4.5 seconds pass before reaching the ground
