Can someone help me with this math question plz i will appreciate it. So this is the question: some of the methods you can use to add or subtract are?.

add: jump strategy, adding up to ten, do the tens last, compensation method, double when the numbers are the same, count from a number upwards

Subtract: take away, minus decrease, leave, how many are left over, difference between, half/halve

Step-by-step explanation:

e) none of the above because the measure of angle cba is 101°

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.
