Which of the following line passes through point (-4,5) and is parallel to the line segment whose endpoints are at (-2,-3) and (
NNADVOKAT [17]

For this case we have that by definition, the equation of a line of the slope-intersection form is given by:

y = mx + b

Where:

m: It's the slope

b: It is the cut-off point with the y axis

By definition, if two lines are parallel then their slopes are equal.

Then, the requested line will have a slope equal to:

m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}} = \frac {5 - (- 3)} {2 - (- 2)} = \frac {5 +3} {2 + 2} = \frac {8} {4} = 2

Thus, the line is of the form:

y = 2x + b

We substitute point (-4,5)and find "b":

5 = 2 (-4) + b\\5 = -8 + b\\5 + 8 = b\\b = 13

Finally, the equation is:

y = 2x + 13

Answer:

y = 2x + 13

Nevermind anyone know this answer???
Semenov [28]

Answer:

x = 6

Step-by-step explanation:

for SPECIAL RIGHT TRIANGLES specifically a 30°-60°-90° triangle.

The longest side is the hypotenuse. The longest side is twice the shortest side. Or the other way around, the shortest side is half the longest side.

Here the longest side (hypotenuse) is 12, so the shortest side is 6.

Also, since you seem to be trying to get this subject.

The long leg is the short leg× sqroot3.

OR the short leg is the long leg ÷ sqroot3. If you end up with a sqroot on the bottom of a fraction, you can't leave it like that. Times top and bottom by sqroot3/sqroot3 to fix it.

If 3x-6y = 9z, which of the following expressions is equivalent to x^2-4xy+4y^2?
Anton [14]

The first and the difficult thing is you need to tell that

x^2-4xy+4y^2 = ( x - 2y )^2

so from question you know 3x - 6y = x - 2y = 9z

finial : ( x - 2y )^2 = ( 9z )^2=81z^2

so the answer is D . Hope this would help you .
