-- A rhombus is always a parallelogram and a quadrilateral.
A rhombus can also be a square, but not all of them are.

-- A rectangle is always a parallelogram and a quadrilateral.
A rectangle can also be a square and a rhombus, but not all of them are.

-- A parallelogram is always a quadrilateral.
A parallelogram can also be a square, a rectangle, or a rhombus, but not all of them are.

-- A quadrilateral can be a square, a parallelogram, a rectangle, and a rhombus.
But not every quadrilateral needs to be any one of these things.

However . . .

-- You can definitely be sure that every square is always a quadrilateral,
a parallelogram, a rectangle, and a rhombus.

All four choices apply to a square, and should be selected.

Effectus [21]

Answer:

5/8

Step-by-step explanation:

there are 8 slices.

if he and his friends eat 5 pieces, they ate 5 out of 8 pieces.

in maths, we write 5 out of 8 like 5/8

hope this helped, any questions - just ask

good luck,

Please help!! :) Thank you!

Let's complete the square

f(x) = x^2 + 6x + 8

y = x^2 + 6x + 8

y-8 = x^2 + 6x

y-8+9 = x^2+6x+9 .... see note below

y+1 = (x+3)^2

y = (x+3)^2-1

note: I added 9 to both sides due to taking half of the 6, and then squaring that result.

We'll restrict x such that $x \ge -3$ to ensure that this function is one-to-one.

Now we need to swap x and y, and solve for y to get the inverse

y = (x+3)^2 - 1

x = (y+3)^2 - 1

x+1 = (y+3)^2

(y+3)^2 = x+1

y+3 = sqrt(x+1)

y = sqrt(x+1)-3

g(x) = sqrt(x+1)-3 is the inverse

The graph is shown below. The original function is in red. The inverse is in blue. The inverse is the result of reflecting the red curve over the dashed line y = x. So this explains why x and y swap places. Consequently, the domain and range also swap as well.

The table represents a function.

hram777 [196]

Answer:

The value of f(5) is:

-8

Step-by-step explanation:

Lets make table which represents the function.

Th table has 2 columns, first column contains values for x, second column contains values of y

The table has 4 rows, which means that there are 4 values of x, which corresponds to 4 values of y.

The table is given as:

x f(x)

-4 -2

-1 5

3 4

5 -8

We need to find the value of f(5).

We can get the value of f(5) if we substitute x = 5 into f(x)

We can see in the table, that if we substitute x=5 in f(x), we get the value of f(5) = -8

Which is the answer

Left to Right

Equality Properties

Multiplication Property of Equality
Division Property of Equality
Addition Property of Equality
Subtract Property of Equality

Step-by-step explanation:

Step 1: Define

10 - 4x ≤ 50

Step 2: Solve for x

Subtract 10 on both sides: -4x ≤ 40
Divide -4 on both sides: x ≥ -10

Here we see that any value x greater than or equal to -10 would be a solution to the inequality.
