Two perpendicular lines have slopes that have product of -1:

The equation of the line BC with slope -1.4 and passing through the point B(4,4) is

Answer:
-4
Step-by-step explanation:
2/5 times -10 = -4
Answer:
One edge of the cube is 5 cm, one edge of the square is 8 cm, so the edge of the cube is 3 cm shorter than the edge of the square.
Step-by-step explanation:
<h3 /><h3>The volume of the cube is found by the formula </h3><h2>V = s³, </h2><h3>where s is the side length (called the edge in this problem)</h3><h3>Since V = 125 cm³, we can take the cube root of 125 to find the edge length.</h3><h3>The cube root of 125 is 5, ( 5³ = 125)</h3><h3>So the edge of the cube is 5 cm</h3><h3 /><h3>The are of a square is found by the formula </h3><h2>A = s² , </h2><h3>where s is the side length (called the edge in this problem) </h3><h3>Since A = 64 cm², we can take the square root of 64 to find the edge length.</h3><h3>The square root of 64 is 8 (8² = 84)</h3><h3>So the edge of the square is 8cm</h3><h3 /><h3>Comparing the two edges tells us that the edge of the cube is 3cm shorter than the edge of the square.</h3>
The value of 5 in the ten-thousands place is 10 times greater than the value of 5 in the thousands place.
You can also say that the value of 5 in the thousands place is 10 times less than the value of 5 in the ten-thousands place.
C is on the line and D is not on the line.
-1/2(-40)+1=21
-1/2(20)+1≠-11
