Drag each equation to show if it could be a correct first step to solving the equation 2(x + 7) = 36. plz help if you cant read it here it is : 1. x+7=18
2. x +14=36
3. 2(x+7)=72
4. (2*x)+(2*7)=36
5. 2x+7=36
6. 2x+14=36

3 answers 1, 6, 4 are your answers

Step-by-step explanation:

b.an increase in a causes b to decrease

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.
