Answer:
the answer would be -12b
Step-by-step explanation:
add 4 plus 3 which equals 7 and 7 plus -5 which equals -12b.
Answer:
Step-by-step explanation:
You can see by the markings that ST is congruent to AY, and that TA is congruent to YS. Those are 2 sides, so so far we have SS. One important thing that comes up WAY TOO OFTEN IN GEOMETRY TO IGNORE is the fact that both of those triangles share the side SA. This is called the reflexive property. The theorem for congruency between these 2 triangles is SSS.
this is using the straight line depreciation formula. you take the initial amount and subtract the amount that it loses each year times x
Answer:
see explanation
Step-by-step explanation:
(a)
Given f( x) = 3x + 4 then to find f(k) substitute x = k into f(x), that is
f(k) = 3k + 4
Now f(k) = k, thus
3k + 4 = k ( subtract 4 from both sides )
3k = k - 4 ( subtract k from both sides )
2k = - 4 ( divide both sides by 2 )
k = - 2
---------------------------------------------------------
(b)
let y = f(x) and rearrange making x the subject
y = 3x + 4 ( subtract 4 from both sides )
y - 4 = 3x ( divide both sides by 3 )
= x
Change y back into terms of x, thus
(x) = 
Answer:
C = 2πr = 16.3 2(3.14)r = 16.3 r = 16.3/6.28 r = 2.5955414 Area: A = πr2 A = 3.14(2.5955414)2 A = 21.15366242
Step-by-step explanation:
The answer would be 21.2
