Write a recursive rule for the sequence 3, 10, 17, 24, --
a. f(1) = 7: fin) = f(n-1)-7
b. f(1) = 17; f(n) = f(n-1)-23
c. f(1) = 3: ſin) = f(n - 1) - 7
d. /(1) - 23: f(n) = f(n-1)
Helpp please!

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
