Parallel lines has equal slopes.
For line, 2x + 3y = 4
3y = -2x + 4
y = -2/3 x + 4/3
i.e. slope is -2/3
Equation of a line is given by y - y1 = m(x - x1), where m is the slope and (x1, y1) is a point on the line.
y - (-4) = -2/3 (x - 1)
y + 4 = -2/3 x + 2/3
3y + 12 = -2x + 2
2x + 3y = 2 - 12
Required equation in standard form is 2x + 3y = -10
Answer:
2 x 10^-7
Step-by-step explanation:
Move the decimal point 'til it becomes a number that is less than 10 and more than 1 then count it.
Also if the point is before the number, it is negative.
Answer:
Step-by-step explanation:
we know that
The given figure is a triangular pyramid
The volume of the triangular pyramid is equal to
where
B is the area of the triangular base
h is the height of the pyramid
Find the area of the base
The base is an equilateral triangle
Applying the law of sines to determine the area
Remember that
substitute
Find the volume
we have
substitute

if one red ball was pulled that mean that now we have 2 red balls 2 green balls and 1 blue ball
and the sum of them is 5 and we have 2 . Soo it is 2/5
Answer:
The radius of the circle is 24 inches.
Step-by-step explanation:
Central angle in a sector is 90 degrees
Area of a sector is
The area of sector is given by the formula as follows :
r is the radius of circle
So, the radius of the circle is 24 inches.
