Answer:
n = -5/2
Step-by-step explanation:
4n - 2 = 6n + 3
-2 = 2n + 3
-5 = 2n
n = -5/2
Answer:
x=3 and y=4
Step-by-step explanation:
The opposite sides of a parallelogram are congruent, or equal.
Therefore, (4x+6) = (7x-3) and (4y-3) = (3y+1)
4x+6 = 7x-3 –– Subtract 4x from both sides
6=3x-3 –– Add 3 to both sides
9=3x –– Divide both sides by 3 to get x alone
3=x
4y-3 = 3y+1 –– Subtract 3y from both sides
y-3=1 –– Add 3 to both sides
y=4
Check by substituting:
4(3)+6 = 7(3)-3
12+6 = 21-3
18 = 18
4(4)-3 = 3(4)+1
16-3 = 12+1
13 = 13
The answer is alternate interior angle theorem.
Explanation: the two angles 3 and 6 are both in the inside and they are opposite sides of each other. Hope I helped!
Answer:
Only the first point lies on the line and thus, Anders is incorrect
Step-by-step explanation:
Here, we want to show that Anders is incorrect
we simply substitute the values of his coordinates into the equation of the line
for (10,420)
we have;
420 = 40(10) + 20
420 = 420
This is right
We now test the second given point;
-420 = 40(-10) + 20
-420 = -400 + 20
-420 is not -380
