Answer:
6
Step-by-step explanation:
(y1-y2)/(x1-x2) = (-1-5)/(0-1) = -6/-1 = 6
Answer:
It's c because you times 2500 by .07 then add that amount to 2500.
4x + 5y - 3 = 0
4x + 5y = 3
3x - 7y - 13 = 0
3x - 7y = 13
4x + 5y = 3......multiply by 3
3x - 7y = 13....multiply by -4
---------------
12x + 15y = 9 (result of multiplying by 3)
-12x + 28y = - 52 (result of multiplying by 4)
---------------add
43y = -43
y = -43/43
y = -1
3x - 7y = 13
3x - 7(-1) = 13
3x + 7 = 13
3x = 13 - 7
3x = 6
x = 6/3
x = 2
so ur solution is : (2,-1) <==
Answer:
m∠1=80°
m∠2=112°
m∠3=131°
m∠4=80°
m∠5=37°
Step-by-step explanation:
First you have to find m∠2
To do that find m∠6 (I created this angle shown in pic below)
Find m∠6 by using the sum of all ∠'s in a Δ theorem
m∠6=180°-(63°+49°)
m∠6=68°
Now you can find m∠2 with the supplementary ∠'s theorem
m∠2=180°-68°
m∠2=112°
Then you find m∠5 using the sum of all ∠'s in a Δ theorem
m∠5=180°-(112°+31°)
m∠5=37°
Now you can find m∠1
m∠1=180°-(63°+37°)
m∠1=180°-100°=80°
m∠4 can easily be found too now:
m∠4=180°-(63°+37°)
m∠4=80°
m∠3=180°-49°
m∠3=131°
