Which property is shown? –7 + 0 = –7

Mathematics
1 answer:
JulsSmile [24]4 years ago

Answer:

OPTION D: Identity property of Addition.

Step-by-step explanation:

In addition, the identity element is the element, 'e' which when added to any element in the set does not alter the value.

We have, for an element 'a',

                                       a + e = a = e + a

So, here, 0 is added to -7 and the value is not changed.

i.e., - 7 + 0 = - 7

Hence, 0 is the identity element of addition.

Note that 1 is the identity element of multiplication.

A rectangular floor is 18ft long and 12 ft wide. Lamar wants to carpet the floor with carpet tiles sold by square yard. Use the
WITCHER [35]

Solution

The dimension of the rectangular floor is 18ft long and 12 ft wide

Using the conversion table

It is given that 1yd =3 ft

This shows that

12 feet will be equivalent to

\frac{12}{3}=4yd

Also 18ft will be equialent to

\frac{18}{3}=6yd

Therefore the new dimension is 6 yard by 4 yard

The area will be

A=6\times4

Therefore the required area is

A=24yd^2

Answer:

x = 137

Step-by-step explanation:

Step-by-step explanation:

∠43° and ∠x° are same side exterior angles as they are on the same side as the transversal but outside the parallel lines. The 2 angles are supplementary, hence

x + 43 = 180 ( subtract 43 from both sides )

x = 137

Explain how to determine whether a point is a solution to a linear inequality?
Orlov [11]

Answer:The solution of a linear inequality in two variables like Ax + By > C is an ordered pair (x, y) that produces a true statement when the values of x and y are substituted into the inequality.

Example

Is (1, 2) a solution to the inequality

2x+3y>1

2⋅1+3⋅2>?1

2+5>?1

7>1

The graph of an inequality in two variables is the set of points that represents all solutions to the inequality. A linear inequality divides the coordinate plane into two halves by a boundary line where one half represents the solutions of the inequality. The boundary line is dashed for > and < and solid for ≤ and ≥. The half-plane that is a solution to the inequality is usually shaded.

Given f(x) = 3x + 4. Find F-1(7)<br><br> Please help I’ll give you brainiest answer 100points!!!!!
Musya8 [376]

Answer:

f⁻¹(7) = 1

Step-by-step explanation:

Step 1: Write out function

f(x) = 3x + 4

Step 2: Find f⁻¹(x) (or known as inverse f(x))

y = 3x + 4

x = 3y + 4

-3y + x = 4

-3y = 4 - x

y = -4/3 + x/3

Step 3: Plug in 7 into inverse f(x)

f⁻¹(7) = 7/3 - 4/3

f⁻¹(7) = 3/3

f⁻¹(7) = 1
