Point 1 (0, - 2)
Point 2 (8,0)
Slope = (y2-y1)/(x2-x1)= (0-(-2))/(8-0)=2/8=1/4
y-intercept (from the Point 1 (0, - 2)) is -2.
Equation : y=(1/4)x - 2
Coordinates to test are (4,-1).
y=(1/4)x - 2
-1=(1/4)*4 -2
-1=1-2
-1=-1 True
B is the answer I’m 100% sure of it
Answer:
Vol of the cube =Vol of cubiod
Vol of each smaller cube =s×s×s= 4×4×4=64
Vol of cuboid /Vol of each smaller cube = no of cubes that can be obtained
6720/64= 105
Hence 105 cubes can be obtained
( 'x' is not 144 .)
The supplement of an angle is (180 - x) .
The problem says that (2/3) of 'x' is equal to (180 - x) .
180 - x = 2/3 x
Multiply each side by 3 :
( Note: 3 x 180 = 540 .)
540 - 3x = 2x
Add 3x to each side:
540 = 5x
Divide each side by 5 :
<u>x = 108°</u> .
