Answer:
answer is 12
Step-by-step explanation:
First:
-5=-3x
-5/3=x
Not this one, because x is not -5/3
Second:
2x+3y=9
2x=9/2x
X=2.25
Y=-x+2
y-2=-x
-y+2=x
The fourth one
The area of a rhombus is 1/2 times the lengths of the diagonals
A = (1/2)(AC)(BD)
Since the diagonals bisect each other, and ed = 8, BD must be 16. Substituting in this for BD and the given area (168) we get the following:
168 = (1/2)(AC)16
168 = 8(AC)
21 = AC
Answer:
The answer would be D, or
Step-by-step explanation:
A is 540
B is 30
C is 720
D is 360
y = mx + b
When x = 0, b is what is left on the right hand side of the equation. So the point is (0,b). This is more commonly called the y intercept. For example
y = 4x + 6
When x is 0 you get
y = 4(0) + 6
y = 0 + 6
y = 6
So in this case 6 is the y intercept. and the equation becomes y = 4x + 6
Answer: y intercept
