False.

Let x = -1 and y = 1. Then x + y = 0, so that

|x + y| = |0| = 0

but

|x| = |-1| = 1

|y| = |1| = 1

|x| + |y| = 1 + 1 = 2

Answer:

A) I = $171.73

B) $4771.73

Step-by-step explanation:

We are told her loan is $4600 for 7 months.

Thus;

Principal; P = 4600

Time; T = 7 months = 7/12 year

Interest rate is given as 6.4%

Thus; r = 6.4

A) To get the interest, the Formula is;

I = PRT/100

I = (4600 × 6.4 × (7/12))/100

I = $171.73

B) Since interest is $171.73, it means amount she owes after the 7 months = $4600 + $171.73 = $4771.73

HELP PLEASE!! TON OF POINTS. RIGHT ANSWERS ONLY REWARDED. MATH GENIUSES?

Answer:

The graph is shifted 1 unit right

The graph is shifted 2 units down

Step-by-step explanation:

We are given

Parent function as

$f(x)=2^{x+3}-3$

New function as

$g(x)=2^{x+2}-1$

we can also write as

$g(x)=2^{x+3-1}-3+2$

We can see that

1 is subtracted to x-value

and 2 is added to y-value

So, f(x) is shifted right by 1 unit

and

f(x) is shifted up by 2 unit
