Answer:

1 and 2

Step-by-step explanation:

4x+4y=12...eqn1^st

2x+y=4....eqn2^nd×2

multiplying eqn2^nd by 2 and subtract then,

4x+4y=12

-4x-2y=-8

or, 2y=4

or, y=4/2

y=2

again ,

from eqn2^nd

we have,

2x+y=4

or, 2x+2=4

or, 2x=4-2

or, 2x=2

or,x=2/2

x=1

Andrews [41]

Answer:

Step-by-step explanation:

Since displacement is the distance between the journey starting point and the final point if they both are the same the difference becomes zero and hence the displacement.

Displacement = final point - initial point

(both are same)

= same - same

A. What is the monthly payment for a $3,200 five-year loan with an APR of 3%.

madreJ [45]

Answer:

$57.50

Step-by-step explanation:

we know that

The monthly loan payment formula is equal to

$M=\frac{P(\frac{r}{12})(1+\frac{r}{12})^{12t}}{(1+\frac{r}{12})^{12t}-1}$

where

M ----> is the monthly payment

P ---> the amount borrowed

r ---> interest rate as decimal

t ---> length of the loan in years

we have

$t=5\ years\\ P=\$3,200\\ r=3\%=3/100=0.03$

substitute in the formula

$M=\frac{3,200(\frac{0.03}{12})(1+\frac{0.03}{12})^{12(5)}}{(1+\frac{0.03}{12})^{12(5)}-1}$

$M=\frac{3,200(0.0025)(1.0025)^{60}}{(1.0025)^{60}-1}$

$M=\$57.50$
