We can use the formula y2-y1/x2-x1 to find the slope.
1. 2-(-15)/12-5 gives us 17/7. The slope is 17/7.
2. -5-(-20)/6-(-18) gives us 15/24. We can simplify this to 5/8. The slope is 5/8.
3. -19-(-19)/-17-(-18) is 0/1. The slope is 0.
4. -17-3/-11-(-1) is -20/-10. The slope is 2.
Answer:
E = (1, 2)
Step-by-step explanation:
You want ...
(E -G) : (O -E) = 3 : 4
4(E -G) = 3(O -E) . . . . . . . . "cross multiply"
4E -4G = 3O -3E . . . . . . . . eliminate parentheses
7E = 4G + 3O . . . . . . . . . . . add 3E+4G
E = (4G +3O)/7 . . . . . . . . . .divide by 7
E = (4(-5, -1) +3(9, 6))/7 = (-20+27, -4+18)/7 = (7, 14)/7 . . . . fill in G and O
E = (1, 2)
-f - 5(2f - 3)
1. -5 * 2f = -10f
2. -5 * -3 = 15
3. -f - 10f + 15
4.Add like terms,
-f - 10f = -11f.
5.-11f + 15
Answer: -11f + 15
Step-by-step explanation:
divided 20 by 5 times that by 4
20 divided by 5 is 4
4x4 is 16 its 16 you got it right
Remember that cosine is adjacent/hypotenuse. We can plug in the values given for this triangle.
Cos(A) = 5/13.
Don’t use a decimal answer as rounding would be necessary, and therefore you wouldn’t be giving an exact value. Leave your answer as 5/13.
