Step-by-step explanation:

In plane Euclidean geometry, a rhombus is a quadrilateral whose four sides all have the same length. Another name is equilateral quadrilateral, since equilateral means that all of its sides are equal in length.

Maria goes to Applebee's with her 2 friends. They each order an entrée, which costs $15 each, and a soda, which costs $3.50 each

Leona [35]

Answer:

Part A: The total is 57.58

Part B: 19.19 each

Step-by-step explanation:

Part A: 15(3) +3.50(3)=55.50

55.50 plus the 3.75% tip (not really addition i dont know how to find a percentage so i looked that part up) but it come out to $57.58

Part B: 57.58 divided by 3 is $19.19 ( I do 3 because Maria and 2 more friends)

Hope it helps and that it is 100% correct dont come at me if something is wrong with my math

If f(x) = x^2-1 which of the following ordered pairs would be on the graph of f(x)

Alex Ar [27]

These following ordered pairs are on the graph:

(0,1)
(5, 24)
(-2,3)

-------------------------------

An ordered pair (x, f(x)) will be on the graph if replacing them into the equation, we get an equivalence.

-------------------------------

The equation is:

$f(x) = x^2 - 1$

-------------------------------

(0,1)

Here, we test $x = 0, f(x) = 1$

Replacing into the equation:

$1 = 0^2 - 1$

$1 = -1$

False, so not on the graph.

-------------------------------

(0,1)

Here, we test $x = 1, f(x) = 0$

Replacing into the equation:

$0 = 1^2 - 1$

$0 = 0$

True, so on the graph.

-------------------------------

(3,5)

Here, we test $x = 3, f(x) = 5$

Replacing into the equation:

$5 = 3^2 - 1$

$5 = 8$

False, so not on the graph.

-------------------------------

(5,24)

Here, we test $x = 5, f(x) = 24$

Replacing into the equation:

$24 = 5^2 - 1$

$24 = 24$

True, so on the graph.

-------------------------------

(-2,3)

Here, we test $x = -2, f(x) = 3$

Replacing into the equation:

$3 = (-2)^2 - 1$

$3 = 3$

True, so on the graph.

-------------------------------

(-4,-17)

Here, we test $x = -4, f(x) = -17$

Replacing into the equation:

$-17 = (-4)^2 - 1$

$-17 = 15$

False, so not on the graph.

The sum of twice a number and seven is equal to the sum of a number and six. find the number

Ber [7]

The number is -1

Steps:

2x + 7 = x + 6 (Sum of twice a number and 7 is equal to sum of the number and 6.)

2x = x - 1 (Subtracted 7 from both sides.)

x = -1 (Subtracted x from both sides.)

Hope this helped :)

The following is a function, g(x).

Shalnov [3]

Answer:

The value of g(-5) is 15

Step-by-step explanation:

Numerical Value of Functions

We are given the expression:

$g(x)=x^2-10$

The value of g(-5) is calculated by substituting x=-5

$g(-5)=(-5)^2-10$

$g(-5)=25-10$

$g(-5)=15$

The value of g(-5) is 15
