Answer: (2, 8)

Since both equations in the system are equal to y, substitute -4x + 16 for y in the quadratic equation, and then solve for x as follows.

Next, substitute x = 2 into either of the original equations to find the y-value of the solution to the system of equations.

Therefore, the solution to the given system of equations is (2,8).

The solution of the system of equations will be;

⇒ x = 2

⇒ y = 8

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The system of equations are,

⇒ y = - 2x² + 4x + 8

⇒ y = - 4x + 16

Now,

Since, The system of equations are,

⇒ y = - 2x² + 4x + 8  ..(i)

⇒ y = - 4x + 16     ..(ii)

Substitute the value of y from (ii) in equation (i), we get;

⇒ - 4x + 16 = - 2x² + 4x + 8

⇒ - 2x² + 4x + 8 + 4x - 16 = 0

⇒ - 2x² + 8x - 8 = 0

⇒ - x² + 4x - 4 = 0

⇒ x² - 4x + 4 = 0

⇒ x = - (-4) ± √ (-4)² - 4×1×4 / 2×1

⇒ x = 4 ± √16 - 16 / 2

⇒ x = 4 / 2

⇒ x = 2

And, y = - 4x + 16

⇒ y = - 4 × 2 + 16

⇒ y = - 8 + 16

⇒ y = 8

Thus, The solution of the system of equations will be;

⇒ x = 2

⇒ y = 8

Answer:

200.00

Step-by-step explanation:

Cost of 2 television at 2,500.00 each = 2 × 2,500.00

= 5000.00

Cost of 2 television = 5,000.00

Selling price of the undamaged TV = 3000.00

Selling price of the damaged TV = 2200.00

Total selling price = 3000.00 + 2200.00

= 5,200.00

Total selling price = 5,200.00

Profits = selling price - cost price

= 5,200.00 - 5,000.00

= 200.00

Profits = 200.00

Answer:

1891 /3

Step-by-step explanation:

Answer:

1) x = 30

2) x = 11.6

Step-by-step explanation:

1) 2x = 4x - 60   (vertical angles are equal)

subtract 4x from each side of the equation:

-2x = - 60

divide both sides by -2:

x = 30

2) 7x + 16 + 3x + 48 = 180°   (supplementary angles add up to 180°)

combine like terms:

10x + 64 = 180

subtract 64 from both sides of the equation:

10x = 116

divide both sides by 10:

x = 11.6

Step-by-step explanation:

If you leave π as π, it should be 169π square feet

If you do π as 3.14, it should be 530.66 square feet.

If you do π as 22/7, it should be 531 1/7 square feet.

Answer:

[tex] \bf \huge ± 5 [/tex]

Step-by-step explanation:

⟼ - x^ 2 - 8 = - 33

step 1 : add 8 to both sides

⟼ − x² − 8 + 8 = − 33 + 8

⟼ - x² = - 25

step 2 : Divide both sides by -1

⟼ - x² / - 1 = - 25 / - 1

⟼ x² = 25

step 3 : take square root

⟼ x² = 25

⟼ x = ± √25

⟼ x = ± 5

∴ x = ± 5.

The equation that represents Genevieve's brother is y = 18/2.

The equation that represents Genevieve's age:

21 = 3 + 2Y

Where Y represents Genevieve's brother age

In order to determine the required equation, make y the subject of the formula

21 - 3 = 2y

18 = 2y

y = 18/2
