Answer:
(b) a1 = 6, a(n) = a(n -1) +5
Step-by-step explanation:
It helps to recognize the form of a recursive definition for an arithmetic sequence. It looks like ...
Only one of the offered answer choices has this form. That is the correct choice.
Make it y = mx + b form
4y = -2x + 8
Divide by 4
Y = -1/2x + 8
The slope is -1/2
Answer:x=2
y=6
Step-by-step explanation:
-7*x+4*y=10
║minus
-5*x+3*y=8
----------------
-2*x+y=2
y=2+2*x
-------------
-5*x+3*(2+2*x)=8
-5*x+6+6x=8
x=8-6
x=2
-------------------------
-7*2+4*y=10
4*y=10+14
4*y=24
y=24/4
y=6
Mangoes and orange =180
Total fruits will be =x
Total ratio=12
Finding number of bananas =3/12(x)
Total number of fruits = 180+3/12(x)=x
180(12)+3x=12x
2160=12x-3x
2160=9x
X=240
The number of fruits will be 240
