Check whether this is a quadratic equation or not ...
=>>>>> x²-2x = (-2)(3-x) ​

Answers

Answer 1

Answer:

yup it is ...

x²-2x = -6+2x

=> x²-4x +6

Answer 2

By expanding the equation, we can see that it is quadratic.

Is the equation quadratic?

A quadratic equation is any polynomial of degree 2.

Here we have:

x^2 - 2x = (-2)*(3 - x)

Expanding this we get:

x^2 - 2x = -6 + 2x

Moving all to the same side:

x^2 - 2x - 2x + 6 = 0

x^2 - 4x + 6 = 0

This is a polynomial of degree 2, so this is a quadratic equation.

Abigail and her mom want to make matching pairs of polka-dotted pajama pants. So, they go to the craft store to pick out fabric. Abigail needs 4 feet of fabric for her pajamas, and her mom needs 6 feet of fabric. But, the store only sells fabric by the yard. If they buy 4 yards of fabric, how many feet will be leftover?

Answers

Answer: 2 feet

Explanation: A yard is 3 feet.
4 feet for Abigail and 6 for her mother makes 10 feet in total.
4 yards x 3 (to convert to feet, every yard is 3 feet, so you multiply) equals 12 feet.
12 - 10 is 2.

Answers

Answer:

f(x) is a parabola with a vertex at (0, 0) that opens up

g(x) is a parabola with a vertex at (0, 2) that opens up

Step-by-step explanation:

Quadratic equation:  [tex]y = ax^2 + bx + c[/tex]

The graph of a quadratic equation is a parabola.  The value of [tex]a[/tex]determines its orientation.

If [tex]a>0[/tex] then the parabola opens upwards and its vertex is its minimum point.  

If [tex]a<0[/tex] then the parabola opens downwards and its vertex is its maximum point.

Given:

f(x) = x²g(x) = x² + 2

⇒ g(x) = f(x) + 2

So the transformation of f(x) to g(x) is an upward shift of 2 units, or

a translation of f(x) by the vector [tex]\left(\begin{array}{ccc}0\\2\end{array}\right)[/tex].

Therefore, the y-coordinate of the vertex of g(x) will be 2 units more than the y-coordinate of the vertex of f(x).

Therefore,

f(x) is a parabola that opens upwards with a vertex at (0, 0)g(x) s a parabola that opens upwards with a vertex at (0, 2)

A family goes to a theme park. The two grandparents pay 1/3
of the full entrance price. The two parents pay full price and the three children pay half price. A full price tickst costs £5.70. How much was the total cost of admission for the family?​

Answers

grandparents ticket each: £1.90 x 2 = £3.80
parents ticket each: £5.70 x 2 = £11.40
children ticket each: £2.85 x 3 = £8.55
total: £23.75
1/3 x 5.70 = £1.90 (what a grandparent payed)

£1.90 x 2 = £3.80 (the cost for both grandparents)

5.70/2 = £2.85 (what one child payed)

2.85 x 3 = £8.55 (the cost for all three children)

5.70 x 2 = £11.40 (the cost for both parents)

Add them all up

3.80 + 8.55 + 11.40

= £23.75 for the whole family

The circumference of a circle is 10.4mm.
Find the length of the diameter.
Give your answer rounded to 3 SF.

Answers

Answer:

diameter: 3.31 mm

Explanation:

circumference of circle → πd

using the formula:

10.4 = πd

d = 10.4/π

d = 3.31 mm

Answer:

diameter = 3.31 mm (3 sf)

Step-by-step explanation:

Diameter of a circle (d) = 2r  (where r is the radius)Circumference of a circle = 2[tex]\pi[/tex]r  (where r is the radius)
⇒ circumference = [tex]\pi[/tex]d

Given:

circumference = 10.4 mm

⇒ [tex]\pi[/tex]d = 10.4

⇒ d = 10.4 ÷ [tex]\pi[/tex] = 3.31 mm (3 sf)
