The sequence an=an−1+2 is an arithmetic sequence
The first three terms in the sequence are (a) 8, 10, 12
<h3>How to determine the first three terms?</h3>
The sequence is given as:
an=an−1+2
Where:
a1 =8
Start by calculating a2 using:
a2=a1+2
This gives
a2=8+2 = 10
Calculate a3 using:
a3=a2+2
This gives
a3=10+2 = 12
So, we have:
a1 = 8, a2 = 10 and a3 = 12
Hence, the first three terms in the sequence are (a) 8, 10, 12

<em><u>Question:</u></em>
A machine made 2 2/6 pencils in 3 3/4 minutes. How many pencils would the machine have made after 9 minutes?
<em><u>Answer:</u></em>
pencils is made after 9 minutes
<em><u>Solution:</u></em>
Given that,
A machine made 2 2/6 pencils in 3 3/4 minutes
Which means,
Let "x" be the number of pencils made in 9 minutes
Therefore,
This forms a proportion and we can solve by cross multiplying
Thus, pencils is made after 9 minutes
Answer:
F(x)=(x-3)(x+8)(x-11)=0
(x-3)=0, (x+8)=0, (x-11)=0
X=3
X=-8
X=11
comparing value
3x+2=-3x-2
6x=-4
x=-4/6Have solution.
y=-2x+10
y=-2x+10
both are equal <u>So</u><u> </u><u>no</u><u> </u><u>solution</u><u>.</u>
3rd
y=-x+4
y=-x+4
<u>both are equal So no </u><u>solution</u>
4th
3x+y=8
3x+y=9
both are equal <u>So no solution</u>
Your answer would be A. 122° and 58° because both angles have to equal 180°
