Is my student correct?​
tino4ka555 [31]

Answer:

Yes

Step-by-step explanation:

There hasn't been a chemical change, rather, just a physical change. All that had happened was a liquid turning into a solid, which doesn't require a change in elements of the liquid itself.

Which transformation will move polygon ABCD completely into one quadrant?
velikii [3]

Answer:

A) up 5 units

Step-by-step explanation:

Given

See attachment for grid

Required

Which places ABCD in a quadrant

<u>Considering vertical movements</u>

From the x-axis, the distance between each point and the line of the x-axis is (the y coordinates):

A = -4

B =3

C = 7

D = -2

Considering the highest magnitudes in the positive and negative column, we have:

A = -4 and C = 7

A = -4 means that a upward movement by (4 + 1) units will move ABCD completely in a quadrant;

4 + 1 = 5

<em>Hence, 5 units upward -- This represents option (a)</em>

C = 7 means that a downward movement by (7 + 1) units will move ABCD completely in a quadrant

7 + 1 = 8

<em>Hence, 8 units downward</em>

<em />

<u>Consider horizontal movements</u>

From the y-axis, the distance between each point and the line of the x-axis is (the x coordinates):

A = -8

B = -6

C = -3

D =-2

Considering the highest magnitudes in the positive and negative column, we have:

A = -8

A = -8 means that a left movement by (8 + 1) units will move ABCD completely in a quadrant;

8 +1 = 9

<em>Hence, 9 units upward </em>

<em />

<em>(a) answers the question</em>

Arnold is writing a program for a video game for one part of the he uses the rule (x,y) (x+7,y-3) to move points on the screen A
Alex787 [66]

We are given rule

when

input is (x,y)

then output is (x+7 , y-3)

(A)

we are given

input is (-10,0)

so, x=-10 and y=0

now, we can find output

x+7=-10+7=-3

y-3=0-3=-3

so, output is (-3,-3)

(B)

we are given

input is (-7,3)

so, x=-7 and y=3

now, we can find output

x+7=-7+7=0

y-3=3-3=0

so, output is (0,0)

(C)

We know that

x+7 and y-3 are translation rules of function

so, this is function

What is the slope of the line that passes through the points (−8,−1) and (−6,−2)? Write your answer in simplest form.
4vir4ik [10]

Answer:

m = -1/2

Step-by-step explanation:

Recall that slope = (change in y) / (change in x).

Going from  (−8,−1) to (−6,−2), x increases by 2 (because -6 - (-8) = 2), and

y decreases by 1.  Thus, the slope here is

m = (change in y) / (change in x) = (-1) / 2 = -1 / 2

m = -1/2
