Choose the system of equations which matches the following graph: a line includes points 6 comma 1 and 4 comma 0

3x − 6y = 12
9x − 18y = 36

3x + 6y = 12
9x + 18y = 36

3x − 6y = 12
9x + 18y = 36

3x + 6y = 12
9x − 18y = 36

FIRST OPTION

Step-by-step explanation:

To solve this problem you can substitute any of the given points into each system:

Point(6,1)

System #1:

(This system matches the graph)

System #2:

 (The system does not matches the graph)

System #3:

(The system does not matches the graph)

System #4:

 (The system does not matches the graph)

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)

(a) {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …}

(b) $59 398

step-by-step explanation:

(a) the annual sequence of profits

aₙ = a₁rⁿ⁻¹

the model for the sequence of profits is {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …} .

(b) profit after 15 yr

  a₁ = $ 30 000

  r = 1.05

a₁₅ = 30 000 × 1.05¹⁴

a₁₅ = 30 000 × 1.979 93

a₁₅ = $59 398

the profit in year 15 will be $59 398.
