CAN ONE ON U GUYS HELP ME?? I WILL GIVE YOU 50 PTS THE FIRST ONE WILL GET BRAINLIEST!!

1. Let x = Number of nickels

y= Number of quarters

Equation:  (i)

Equation:   (ii)  [∵ 1 nickel = $0.05 , 1 quarter = $0.25]

Multiply equation (ii) by 20, we get

 (iii)

Eliminate (i) from (iii), we get

put y= 10 in (i) ,

Sentence = " Jane has 10 nickels and 10 quarters".

2. Let x = Number of dimes

y= Number of nickels

Equation:  (i)

Equation:   (ii)  [∵ 1 nickel = 5 cents, 1 quarter = 25 cents]

Multiply equation (i) by 5, we get

 (iii)

Eliminate (iii) from (ii), we get

put x=3 in (i) ,

Sentence = " Joey has 3 dimes and 9 nickels".

the factors of 24 are 1, 2, 3, 4, 6, 8, 12 and 24. hope this ! mark brainliest! you v much! : )

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.
