The line l passes through the points (-2,2) and (5,1) Find the gradient of line l

Mathematics
1 answer:
crimeas [40]2 years ago
5 0

Step-by-step explanation:

gradient (m) = y2 - y1 / x2 -x1.

(-2 =x1, 2 =y1) and ( 5 = x2 , 1 = y2).

plug in the values and solve...

m = 1-2 / 5-(-2)

m = -1 / 5+2

m = -1/7 or -0.14.

Hope this helps.

Good luck.

Each sequence below gives an explicit formula. Write the first five terms of each sequence. Then, write a recursive
Bas_tet [7]

Answer:

The first five values are 12, 14, 16, 18 and 20

The recursive formula is as follow

\left \{ {{a_{1} =12} \atop {a_{n} =a_{n-1} } + 2} \right.

Step-by-step explanation:

Since we need to find the first 5 values  we start with n = 1 to n = 5. Note that we don't start from n = 0 as the question states that  n ≥ 1.

For the first 5 values we just replace the value of n with 1, 2, 3, 4 and 5 and calculate the answer

a_{1}  = 2(1) + 10 = 12\\ a_{2} = 2(2) + 10 = 14\\  a_{3} = 2(3) + 10 = 16\\  a_{4} = 2(4) + 10 = 18\\ a_{5} = 2(5) + 10 = 20

The first five values are 12, 14, 16, 18 and 20

A recursive formula is one that

a) Mentions the initial term

b) provides a formula connecting the previous term to the existing term.

Since we know the first term is 12, i.e a_{1} = 12 and we know that the difference between consecutive terms is 2 we can conclude that the recursive formula is made up of the following two formulas

a_{1} = 12

a_{n} = a_{n-1}  + 2

The over all formula is as follow

\left \{ {{a_{1} =12} \atop {a_{n} =a_{n-1} } + 2} \right.
