Select the correct text. Jerome’s teacher gave him a homework assignment on solving equations. Since he’s been thinking about saving for a used car, he decided to use the assignment as an opportunity to model a savings plan. He already has $500, and he plans to save $375 every month. To model the situation, he created this equation, where y represents the total amount saved for the car and x represents the number of months since he started saving: 500 + 375x = y. He then solved the equation to determine how many months he would need to save to have enough to purchase the car. Review his work, and select the error. Justification 1: given 2: addition property of equality 3: simplification 4: division property of equality 5: simplification 6: substitution, y = 3,500 7: simplification Step 1:500 + 375x = y Step 2:500 + 375x − 500 = y − 500 Step 3: 375x = y − 500 Step 4: = Step 5: x = Step 6: x = Step 7: x = 8

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.

or

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:

  ⇒

then, the solutions are: or

nothing extraneous has been found!

answer: its the third option.

i just took the test.

nope lol
