Step-by-step explanation:
Precision is when you know the exact measurement like 4.756
Accuracy is when your kind of close to the precise measurement like 4.75
Precision means exact and accuracy means close enough.
Answer:
adding both equations
4x+9y=5
-4x+7y=11
+ + =+
________
0 +16y=16
y=1
putting the value of y in first eqn
4x+9×1=5
4x=5-9
4x=-4
x=-1
so the x is -1 and y is 1
Step-by-step explanation:
The statements are
1.Draw Oa,Ob
2.OR is perpendicular to AB
3.OR is congruent to OR
4.OA is congruent to OB
5.Triangle AOR is congruent to BOR.
6.AR is congruent to AB.
The reasons are
1.Auxalaritly lines
2 Radius are perpendicular to tangent
3.Reflexitive
4.Radii of same circle are equal
5.HL theorem, (since we know hypotenuse and a leg)
6.CPCTC
Answer:
1st number: 3
2nd number: 18
3rd number: 19
Step-by-step explanation:
let 'f' = 1st number
let '6f' = 2nd number
let '6f + 1' = 3rd number
f - 2(6f + 1) = -35
f - 12f - 2 = -35
-11f - 2 = -35
-11f = -33
f = 3
