Because x doesn’t repeat
Answer:
c
Step-by-step explanation:
you know what output you get from the input.
For example, you know that if you put in -5, you get -2, or if you put in 4, you get -2.
Even though there are two inputs for one output, it is still a function.
------------------------------------------------------------------------
If there are two outputs for one input, it is not a function.
For example, on d, when -5 is an input, you don't know if you're going to get 3 or 7. So, it's not a function.

Answer: 20 servings
Step-by-step explanation:
From the question, Sara is having a dinner party for four friends and she needs to reduce the serving size of the meatloaf recipe. Sara used the equation x/4=5 . To get the number of servings the recipe originally made, we have to find the value of x.
x/4 = 5
x = 4 × 5
x = 20
This means that the recipe that was used originally made 20 servings.

[tex]\sqrt{64}[/tex]=±8
Answer:
B. -8 and 8
Step-by-step explanation:
To solve this equation, we need to get x by itself. To do this, perform the opposite of what is being done to the equation. Keep in mind everything must be done to both sides of the equation.
x^2=64
x is being squared. The opposite of being squared is taking the square root. Take the square root of both sides.
√x^2=√64
The exponent and square root on the left will cancel, and x will be left by itself.
x=√64
x=±8
The solutions of the equation are x=8 and x= -8
Therefore, the answer is B. -8, 8

The surface area of a cube is 600 square inches. What is the area of one of its faces?
A.
6 square inches
B.
36 square inches
C.
75 square inches
D.
100 square inches
Answers
Answer:
D.
Step-by-step explanation:
area of a square = side^2
area of a cube = 6 x side^2
let the side be a .
6a^2 = 600
=> a^2 = 600/6
=> a^2 = 100
Hence the area of one of its faces is 100 square inches.
or in plain terms without using those formulas,
6 faces of the cube have 600 square inches
=> 1 face of the cube has 600/6 = 100 square inches

Step-by-step explanation:
(2a + [tex]\frac{1}{2a}[/tex] )² = 4a² + 2 + [tex]\frac{1}{4a^2}[/tex] , thus
10² = 4a² + 2 + [tex]\frac{1}{4a^2}[/tex] ( subtract 2 from both sides )
100 - 2 = 4a² + [tex]\frac{1}{4a^2}[/tex] , that is

The expression 2(a+b)=−8.1 for certain values of a and b. Find the value of the following expressions for the same values of a and b: −0.5(a+b)
Answers
Answer:
Interpreting as: 2(a+b)=-8.1
Input:
2 (a + b) = -8.1
In Given the expression
2( a + b) = 8.1 ..........................(1)
now divide both sides of the first equation by 2 ,
2 (a + b) /2 = 8.1 /2
(a + b) = 4.05
expression -0.5(a + b) ................(2)
simply put the value of (a + b) in (2),
- 0. 5( 4.05) = -0.5 * 4.05
= 2.025
Value of expression is 2.025.

A parallelogram has rotational symmetry and triangle has no points of symmetry. Therefore, option 4 and 5 are correct answers.
What is a point symmetry?Point Symmetry is when every part has a matching part the same distance from the central point but in the opposite direction. It looks the same when viewed from opposite directions (180° rotation).
1) A figure has point symmetry, if it has a rotational symmetry of 180 degrees.
2) An object is said to possess rotational symmetry if it takes the same shape before and after its rotation along its point of rotation.
3) In order for a figure to have reflectional symmetry, there needs to be at least one axis such that when the the figure "folds" over that axis it maps into itself.
4) A parallelogram has rotational symmetry. A parallelogram does not have reflectional symmetry.
So, all parallelograms have point symmetry.
5) Triangle has no points of symmetry, because there is no up and down shapes in triangle
A parallelogram has rotational symmetry and triangle has no points of symmetry. Therefore, option 4 and 5 are correct answers.
