Please help. thank u

sineoko [7]

Answer:

i)vertical

ii)horizontal

iii)oblique

Step-by-step explanation:

When an equation is just x=a number, it is a horizontal line.

When the equation is just y=a number, it is a vertical line.

If the equation is the full y=mx+b, it is oblique.

2x=5

x=2.5

vertical

y+2=-1

y=-3

horizontal

x+y=3

y=-x+3

oblique

:) ur welcome

Find all solutions to the differential equation dy dt = 1 − y 2

klemol [59]

Try this:
$\frac{dy}{dt}=1-y^2; \ =\ \textgreater \ \ \frac{dy}{y^2-1}=-dt; \ =\ \textgreater \ \ ln| \frac{y-1}{y+1}|=-2t+C.$
If it is possible, modify result to form more compact.

Is (1,2) the point of intersection of y=3x-1 and y=-x+3?

Luden [163]

Answer:

yes

Step-by-step explanation:

Solving the 2 equations to find the point of intersection

y = 3x - 1 → (1)

y = - x + 3 → (2)

Since both equations express y in terms of x, equate the right sides

3x - 1 = - x + 3 ( add x to both sides )

4x - 1 = 3 ( add 1 to both sides )

4x = 4 ( divide both sides by 4 )

x = 1

Substitute x = 1 into either of the 2 equations for corresponding value of y

Substituting x = 1 in (2)

y = - 1 + 3 = 2

Thus (1, 2) is the point of intersection

Given that D is the midpoint of AB and B is the midpoint of AC, which statement must be true? A line has points A, D, B, K, C. A

lubasha [3.4K]

Answer:

AC = 4DB

Step-by-step explanation:

see attachment

Given that B is the midpoint of AC, this means that AB≅BC.

Also, D is the midpoint of AB, therefore AD≅DB.

This shows that AD is 1/4 of the length of AC, since it is 1/2 of the length (1/2 x 1/2 = 1/4). DB is the same length, since it is congruent to AD.

Thus, AC = 4DB.
