Y= 5x – 1
- 15x - 3y = 3
how many solutions does this linear system have?

infinite solutions

Step-by-step explanation:

To find how many solutions the system has, solve the system.

y = 5x-1

-15x -3y = 3 First simplify the second equation

y = 5x-1

-5x +y = -1 Next, move -5x to the right side of the equation so you can solve it using substitution.

y = 5x-1

y =5x -1 When you do this, you see that both equations are the same, this means that there are infinite solutions.

step-by-step explanation:

answer: c, the green line

step-by-step explanation:

there is no black line, eliminate b.

simple interest implies periodic payments, but the red line shows no payments, eliminate d.

simple interest has equal payments. if paid say every day, the graph is about a straight line (actually a stairstep).

the yellow line is not straight, eliminate a.

check: the green line is straight, answer is c.

simple interest with positive interest rate gives a straight line sloping up to the right. green line:

g(t) = $100 + ($200-$100) ÷ (20 years) × (t years)

= $100 + (4%/year) × ($100)(t years)

incidentally, the yellow line curving upward represents continuously compounded interest

y = $100 × 2^(t years / (14 assuming the yellow line hits $200 at 14 years. 2^0 is 1, so y(0) = $100; 2^(14/14) is 2, so y(14) = $200.
