can someone help please ):
Answer:
A function is a relation that maps elements from one set (the domain, the set of the inputs) into elements from another set (the range, the set of the outputs). Such that each element of the domain can be mapped into only one element of the range.
Now let's analyze the given relations.
1)
Here we can see that the inputs are -3, -1, 1, and 2.
Then the domain (the set of the inputs) is:
D = {-3, -1, 1, 2}
And we can see that the outputs are 0, 2, and 5.
Then the range is:
R = {0, 2, 5}
We also can see that each input is being mapped into only one output, then this relation is a function.
2) In this case the inputs are -2, -3, and 5.
Then the domain is:
D = {-2, -3, 5}
And the outputs are 6, 7, 8
Then the range is:
R = {6, 7, 8}
And we can see that each input is mapped into only one output, then this relation is a function.
3) In this case we can see that the inputs are -4, -2, and 0
Then the domain is:
D = {-4, -2, 0}
And we can see that the outputs are -2, -1, 3, and 4.
Then the range is:
R = {-2, -1, 3, 4}
In this case, we can see that the input -4 is being mapped into two different outputs (3 and -1)
Then this relation is not a function.
: Brianna’s teacher asks her which of these three expressions are equivalent to each other. Expression A: 6x + 4 Expression B: 12x + 4 Expression C: 5x + x + 4 Briana says that all three expressions are equivalent because the value of each one is 4 when x = 0. Do you agree or disagree with Brianna?
Answer:
I disagree with Brianna.
Step-by-step explanation:
Expression A: 6x + 4
6(0) + 4
4
6(1) + 4
6 + 4
10
6(2) + 4
12 + 4
16
Expression B: 12x + 4
12(0) + 4
4
12(1) + 4
12 + 4
18
12(2) + 4
24 + 4
28
Expression C: 5x + x + 4
5(0) + (0) + 4
4
5(1) + (1) + 4
5 + 1 + 4
10
5(2) + (2) + 4
10 + 2 + 4
16
It is true that when you substitute the “x” in each expression with 0, you get 4. However, when you sustitute a different number, like 1 or 2, you get completely different answers. In order for these expressions to all be equal, they have to all get the same answer each time. Yet, notice how both expressions A and C got the same answer every time. This is because when you simplify expression C, you get 6x + 4 (when you add together 5x and x). Therefore, expressions A and C will always be equivalent.

A school has a parking lot that is 150.23 feet by 135.12 feet. What is the perimeter of the parking lot?
Answer: 570.70 ft
Step-by-step explanation:
The perimeter is the distance around the entire parking lot.
The measurement of 150.23 ft by 135.12 ft is half of the distance of the lot because it represents just two sides yet there are 4 sides.
The other two sides have the same measurement as this is a rectangle.
The perimeter of the parking lot is:
= (150.23 * 2) + (135.12 * 2)
= 570.70 ft

Answer: 15.4 m
Step-by-step explanation:
The area of a parallelgoram is:
A = bh,
where b is the base and h is the height.
We know that the base is 7.7 meters, and the height is 2 meters, so we can substitute:
A = 7.7 (2)
A = 15.4 m

Marla has 1\2 of a pound of candy. She equally distributes the candy into 4 bags. How much candy will go in each bag?
Answer:
1/8 or 8
Step-by-step explanation:
At a party there are 90 people.
48 are women and 42 are men.
Some women leave.
Some men arrive.
The ratio of women to men is now
10:11
Are there now more than 90 people at the party?
Show working to support your answer.
Answer:
No
Step-by-step explanation:
Originally:
48:42
If some leave and some arrive = 10:11 given in question
So 48- 8 leave = 40 women
Therefore 42+2=44
Now the ratio is 40:44 (Actual amount of people)
When you simplify/ divide by 4 = 10:11
Total amount of people is 40+44= 84 which is less than 90

An elephant at an animal sanctuary weighs 5.5 tons. He receives a daily nutritional supplement. The instructions say to give 1 fluid ounce of supplement for every 250 pounds of body weight. How many fluid ounces of supplement should the elephant receive? no options I need to type it in.
Answer:
44 fluid ounces.
Step-by-step explanation:
It's important to keep in mind that 1 ton is 2,000 pounds.
5 x 2,000 = 10,000 pounds.
You have to add 1,000 pounds because of the '.5' at the end of the 5. That leaves you with 11,000 pounds.
Now, you have to divide by 250 to find how many fluid ounces you need.
[tex]\frac{11,000}{250}[/tex] = 44.
You need 44 fluid ounces of supplement.
Answer:
44

Mr. Strand mowed 2 5 of his lawn. His son mowed 1 3 of it. Who mowed most of the lawn? How much of the lawn still needs to be mowed?
Answer:4/15 of the portion of land is left to be mowed.
Step-by-step explanation:
Portion of Lawn mowed by Mr Strand =2/5
Changing to decimal we have 0.4
Portion of Lawn mowed by his son=1/3
Changing to decimal, we have 0.333
From this , we can deduce that Mr Strand mowed most of the Lawn.
Now to find the portion of Lawn remaining to be mowed
Let total portion be =1whole
Such that portion left to be mowed
=1-(2/5+1/3)
1- 6 + 5/15
1-11/15
15/15 -11/15
4/15 of the portion of land is left to be mowed.

Answer: <ACB = 50 degrees
Step-by-step explanation: Since the interior angles of a triangle is always equal to 180 degrees, you would add both given degrees which is 40 and 90 (because of the right angle) and then subtract that answer (130) from 180
Find the slope-intercept form from the two points (0,8)
and (1, 10).
Answer:
y = 2x + 8
Step-by-step explanation:
We want an equation of the form y = mx + b (slope-intercept).
Look what happens to x as we go from (0, 8) to (1, 10): x increases by 1. This is the 'run' as we calculate the slope.
At the same time, y increases by 2 from 8 to 10.
The slope is defined as m = rise / run, and here is m = 2/1, or m = 2.
Write out y = mx + b and substitute 2 for m: y = 2x + b.
To find the y-intercept, substitute 0 (from (0, 8) ) for x and 8 for y:
8 = 2(0) = b, so b = 8, and the desired equation is
y = 2x + 8
