solve the system of equations -3x+2y=-3 and -x-y=-11 by combining the equations

Answers

Answer:

x = 5

y = 6

Step-by-step explanation:

-3x + 2y = -3

-x - y = -11 (Multiply everything by 2)

-3x + 2y = -3

-2x - 2y = -22

-5x = -25

x = 5

-x - y = -11

-5 - y = -11

-y = -11 + 5

-y = -6

y = 6

Please give a step-by-step solution of 2x^2 +12x = 6 (by completing the square)

Answers

Answer:

x = - 3 ± 2[tex]\sqrt{3}[/tex]

Step-by-step explanation:

Given

2x² + 12x = 6 ( divide through by 2 )

x² + 6x = 3

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(3)x + 9 = 3 + 9

(x + 3)² = 12 ( take the square root of both sides )

x + 3 = ± [tex]\sqrt{12}[/tex] = ± 2[tex]\sqrt{3}[/tex] ( subtract 3 from both sides )

x = - 3 ± 2[tex]\sqrt{3}[/tex] ← exact solutions

The table below shows a portion of the planned budget

Housing Expenses
$1,500
Which of the following shows the percentage of income
used for housing expenses?

Answers

The housing expense is $1,500/$6,000 = .25 or 25%

Answer:

You subtract 6,000 by 700= 5,300 Then you subtract 550 by what you got which was 5,300 so the way you do it is now you subtract even more then 550 so 550 by 5,300=4,750 which you basically the answer is 20%

Myra owns a car service that charges a $5 flat rate and an additional $0.50 per mile.
Write an equation that represents this information.

Answers

Answer: 5 + 0.5m

Step-by-step explanation:

Let the number of miles be represented by m.

Therefore, since there's a $5 flat rate and an additional $0.50 per mile, this can be formed into a equation as:

= 5 + 0.5m

For example if the number of miles taken is 100miles, the amount charged will be:

= 5 + 0.5m

= 5 + 0.5(100)

= 5 + 50

= $55

Answers

Answer:

Square; x=2; y=1

Step-by-step explanation:

Being that the following quaderlateral has equal sides and angles equal to 90 degrees each, it would be classified as a square.

Now, knowing that they have all equal sides, you could say that

1). 5x-4=3x

as well as

2).2y+4=5y+1

Now, solve for each of the variables:

1). 5x-4=3x

(Minus 3x from both sides and add 4 to both sides)

2x=4

(Divide by 2)

x=2

2). 2y+4=5y+1

(Minus 5y from both sides and minus 4 to both sides)

-3y=-3

(Divide by -3)

y=1

What are Fractions?

Fractions are type of numbers which are written in the form p/q, which implies that p parts in a whole of q.

Here p, called the numerator and q, called the denominator, are real numbers.

Given fraction is 1/4.

When 1/4 is multiplied by 1/2,

1/4 × 1/2 = 1/8 which is less than 1.

If 1/4 is multiplied by 3/4,

1/4 × 3/4 = 3/16, which is less than 8.

The least number that 1/4 is multiplied to gives the number 1/4 itself when multiplied by 1.

So, any number less than 1 when multiplied to 1/4 gives the number less than 1/4.

Hence the correct option is (c).
