Answer:
d = 3 sqrt(2)
Step-by-step explanation:
To find the distance between two points we can use the formula
d = sqrt( (x2-x1)^2 + (y2-y1)^2)
d = sqrt( ( -1 - -4) ^2 + (9-6)^2)
d = sqrt( (-1+4)^2 + 3^2)
d = sqrt( 3^2+3^2)
d = sqrt(9+9)
d = sqrt(18)
Simplifying
d = sqrt(9*2)
d = 3 sqrt(2)
Answer:
B C and F
Step-by-step explanation:
Polygons are closed shaped with straight lines
D and E have curves therefore they cannot be classified as polygons
A is not closed therefore it A is not a polygon
B, C and F are closed and use only straight lines therefore those 3 are polygons
Answer:
Step-by-step explanation:
Answer:
No
Step-by-step explanation:
equation is y=2x+3
The point we have is (15,29)
i.e. x=15 and y=29
if we put x=15 in the equation we should get the value of y=29
y=2(15)+3
=30-3
=27
Here, we didn't get y=29 instead we got y=27
So the point (15,29) doesn't follow that equation
Answer:
These lines are perpendicular.
Step-by-step explanation:
Put both equations in the slope intercept form of a line.
y = -6x - 8 This is already in the slope intercept form for a line
-x + 6y = 12 Add x to both sides of the equation
6y = x + 12 Divide through the whole equation by 6
y = 1/6x +2
Now we compare the two slopes of -6 and 1/6. They are negative reciprocals of each other. That means that the line are perpendicular.
