What is the first step to simplify the expression 5x – x(2 – 3x) + 2?

"distribute to the terms inside the parentheses"

Step-by-step explanation:

Looking at this specific problem, we see that the terms inside parenthesis are ALREADY SIMPLIFIED, so disregard this step.

There aren't any square/cube to EXPAND, so disregard this step as well.

There IS DISTRIBUTION in this problem. Distributing -x with the term inside the parenthesis, (2-3x). Hence, distribution should be the FIRST STEP of this problem.

Fourth answer choice is right.

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.

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
