<em>Coplanar</em> means "lying on the same plane," while <em>colinear </em>means "lying on the same line." In this problem, all four points A, B, C, and D are coplanar - they all lie on the plane 
- so we just need to find the points that lie on the same line. Though points C and B <em>would </em>be colinear if there was a line drawn between them, there's no such line in this problem, so we can rule that out. We notice one line drawn on the plane, and points A, C, and D lying on it, so we can say that points A, C, and D are both coplanar and colinear.
Answer:
Ans of No.3
C 40÷(x+4)
Step-by-step explanation:
question 40÷(4+x)
ans nothing changed but x move to front of 4 and 4 move behind of x
Answer:
-17 - 3 = -20
Step-by-step explanation:
- Let's start by representing the equation numerically, with x representing "a number." Less than tells us to subtract:
x - 3
- Now the problem says that "the number" is equal to -17, so plug in -17 for x.
-17 - 3 = -20
- (If this is difficult, think of it like -17 + -3 = -20. That always helps me!)
Answer:
Solution = -2x-7y=-4
Step-by-step explanation:
Add the x-component to the x-component, add the y-component to the y-component, add the number to the number.
It looks like this
5x + (-7x) = -2x
9y + (-2y) = -7y
1 + (-5) = -4
Then, put the solutions in the places where you see them in the equation, x goes first, y comes second, then this equals the number value.
-2x - 7y = -4
Answer:
3
Step-by-step explanation:
If you start at any point on the line, you can go up 3 points and go to the right by 1 point to get back to the line. This is where you get the number 3 because 3/1 is 3.
