Can someone help me solve these systems using elimination?

8x-6y=-20

-16x+17y=30

Please show your steps so I can learn too. Thank you

Step-by-step explanation:

8x-6y=-20

y = mx + b in which is the slope intercept of the line where m is the slope and b is the y intercept.

converting to y = 4 x + 10

3. 3

for the line in the form of y = mx + b, the slope is m and y intercept is b.

I think so and I hopefully it works..

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.
