since the equation of the line passing through the given point is perpendicular to the given line(m2= -1/m1)
using the formula y=mx+c
y=2/3x +1
m1=2/3
m2= -1/2/3
m2= -3/2
the slope of the second line is -3/2 and it passes through the point(3,-2)
using the formula y-y1 = m(x-x1)
y-(-2)= -3/2(x-3)
y+2= -3/2(x-3)
multiply both sides by 2
2(y+2) = -3(x-3)
2y+4 = -3x+9
2y = -3x+5
y= -3/2x + 5/2
Answer:
665 ft^3
Step-by-step explanation:
The formula to find the volume of pyramids is 1/3 x length x width x height. One way to solve this is by multiplying the length, width and height, and then dividing it by 3.
14 x 9.5 x 15 = 1995
1995 / 3 = 665
So the volume is 665 cubic feet
I hope this helps :)
Answer:
2^2×20
Step-by-step explanation:
2^2×20
because 2×20=40
so, 2^2×20=2^40
K= 2
The square is doubled so the scale factor (k) is 2
Answer:
Step-by-step explanation:
13x+2y=1
+ 5x-2y=-19
-------------------
18x=18
x=1
5x1-2y=-19
5-2y=-19
-2y=-19-5
-2y=14
-y=7
y=-7
x=1
y=-7
