Which statements are true about the ordered pair (5, −6) and the system of equations? {x+y=−1 3x−y=21 Select each correct answer

Likurg_2 [28]

The correct options are:

The ordered pair (5, −6) is a solution to the first equation because it makes the first equation true.

The ordered pair (5, −6) is not a solution to the system because it makes at least one of the equations false.

Step-by-step explanation:

Given equations are:

$x+y=-1\\3x-y=21$

first of all we have to put the point in both equations to check if the point holds true on both equations

So,

Putting the point in the first equation

$x+y=-1\\5-6=-1\\-1=-1$

Putting the point in second equation

$3x-y=21\\3(5)-6=21\\15-6=21\\9\neq 21$

So,

The correct options are:

The ordered pair (5, −6) is a solution to the first equation because it makes the first equation true.

The ordered pair (5, −6) is not a solution to the system because it makes at least one of the equations false.

Answer:

Step-by-step explanation:

Area of a rectangle is given by:

....[1]

where

l is the length

w is the width of the rectangle respectively.

As per the statement:

the length of a rectangle is four times its width.

⇒

It is also given that: area of rectangle is 1024 cm square

Substitute the given values in [1] we have;

⇒

Divide both sides by 4 we have;

Taking square root both sides we have;

Therefore, the width of the rectangle is, 16 cm

Uta invests an amount into a compound interest investment account that pays 6% a year. After six years, she withdraws her total

AnnZ [28]

Answer: $352.48

Step-by-step explanation:

Hi, to answer this question we have to apply the formula:

A = P (1 + r)^t

Where

A: total balance after invest

P: principal amount invested

r = interest rate (in decimal form)

t = time (years)

Replacing with the values given:

500= P (1+0.06)^6

Solving for P:

500 = P (1.06)^6

500 / ( (1.06)^6)=P

500 / 1.4185 =P

$352.48= P
