Answer: The 12th term is 46x -25
Step-by-step explanation:
It is increasing by 4x and decreasing by 3 through each term, this represents the d. a1 has already been identified as 2x +8, so you just have to write down the formula and the solve form there by plugging in the 12 in (n-1) to find the answer.
Answer:
2.
Step-by-step explanation:
The gradient or slope of a straight line which is found between two points (x1, y1) and (x2, y2) is given by the formula:
m = (y2 - y1) / (x2 - x1)
Where y2 = 7
y1 = 3
x2 = 4
x1 = 2
=> m = (7 - 3) / (4 - 2)
m = 4 / 2 = 2
The gradient is 2.
Let n be the amount of points earned in round 5
the goal of the game is to get zero when you add up the point value from all the rounds.
this means
-9 +3 + (-8)+ 2 +n =0
add up all the given numbers, then see which number(n) is required in order to get zero

Answer:
6
Step-by-step explanation:
96÷5=19.2
<u>96÷6=16</u>
96÷10=9.6
96÷14=6.857142~
bearing in mind that perpendicular lines have negative reciprocal slopes, so

so we're really looking for a line whose slope is 3 and runs through (1,5)
