What is -1/2+1/3 , -3 1/5+(-6 1/2) , 5//8) , -9/10-2/5 , 6 3/ 1/5) answer all in sum or difference

Part a)

the answer Part a) is

Part b)  

we know that

substitute

therefore

the answer part b) is

Part c)

therefore

the answer part c) is

Part d)

therefore

the answer part d) is

Part e)

we know that

substitute

therefore

the answer Part e) is

Step-by-step explanation:

1.

We solve it by taking LCM (-3 + 2) / (3 x 6) = 1/6

2.

By taking LCM:

-3 1/5 = (-3 x 5 + 1) / 5 = -16/5

-6 1/2 = - (6 x 2 +1) / 2 = -13/2

Subtracting these values:

-16/5 + (-13/2) = -97/10

3.

Adding the fraction to get: 5/8 + 2/8 = 7/8

4.

Taking the LCM:

(-9 - 4) / 10 = 13/10

5.

Taking the LCM to get:

33/5 + 11/5 = 22/5

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.

if you was gonna solve for a, a is a   < -12
