Answer:
see explanation
Step-by-step explanation:
Note the common difference d between consecutive terms
d = 10 - 3 = 17 - 10 = 24 - 17 = 7
This means the sequence is arithmetic with n th term
= a₁ + (n - 1)d
Here a₁ = 3 and d = 7, thus explicit formula is
= 3 + 7(n - 1) = 3 + 7n - 7 = 7n - 4, thus
= (7 × 18) - 4 = 126 - 4 = 122
2y+8x=21
This is in standard form, lets convert to slope intercept form
slope intercept form : y = mx + b
2y + 8x = 21
-8x -8x
2y = -8x + 21
y = -4x + 21/2
Answer: m = -4
Answer:
Step-by-step explanation:
Here, the given expression is
Now, simplifying the brackets, we get
=
Now, operate on the like terms.
=
=
Hence, the given expression is simplified to the quadratic equation
3(41x+400) simplified = 123x+1200
