What are the domain and range of each relation?
Drag the answer into the box to match each relation.
Answers
Answer:
Please check the explanation.
Step-by-step explanation:
We know that the domain of a function is the set of input or argument values for which the function is real and defined.Thus, the domain of the first relation is: {-2, -1, 0, 2}
We also know that the range of a function is the set of values of the dependent variable for which a function is defined.Thus, the range of the first relation is: {-4, -2, 2}
Given the second relation
x y
-4 -2
-2 1
1 4
4 4
We know that the domain of a function is the set of input or argument values for which the function is real and defined.Thus,
The domain of the second relation is: {-4, -2, 1, 4}
We also know that the range of a function is the set of values of the dependent variable for which a function is defined.Thus,
The range of the second relation is: {-2, 1, 4, 4}

Factor 5x^2-11x+6. Rewrite the trinomial with the X-term expanded using 2 factors
The answer starts as 5x^2_______+6
Answers
Answer:
[tex]5x^2-5x-6x+6[/tex]
Step-by-step explanation:
[tex]5x^2-11x+6\\5x^2-5x-6x+6[/tex]
we need to factorize it so the X-term expanded should satisfy two conditions
1) +5 times +6 should be +30
2) add or subtract any two numbers which multiply and give -11
so here -5 times -6 gives +30 and -5 added to -6 equals -11

Nicholas started a canned-food drive at school. The equation representing this is y = 235x + 15, where x is the number of days, and y is the number of cans collected. Explain how to determine how many days it would take to collect 2600 cans.WILL GIVE BRAINLIEST
Answers
Answer:
well, 11 days
Step-by-step explanation:
if you were to put take out the y and put 2600 in the y place (2600=235x+15)
you solve that, and will come to 11 days
further explaining:
2600-15 = 2585
2585 / 235 = 11
( I'm not sure if this is right, the question is worded weird and almost doesn't make sense)
but I think it is looking for substitution
Hope this helps!
Answer:
I am given a number of cans, which is y, and I need to find the number of days, which is x. To do this, I would substitute 2600 for y, to get 2600 = 235x + 15. Solving for x, I would get x = 11. Thus, it would take 11 days to collect 2600 cans.

because the value of terms are going up by 4 every time, so if you subtract 4 you get 2 and the position would be 0 making 2 the y-intercept and then slope is= rise/run and the equation is rising 4 units for every 1 unit moved, so the slope is 4/1 or 4. plug all of that into the equation and you get 4n + 2

whats the percent increase from 45 to 56
Answers
Answer:
24.44%
Step-by-step explanation:
1) Find the difference between 45 and 56 as a number.
2) Divide the result from Step 1 by the starting number 45.
3) Multiply the result from Step 2 by 100 to get it in terms of percent.
The three steps above can be made into a formula. Thus, to find the percent change from 45 to 56, we use this formula:
((Y-X)/X)*100 = Percent Change
X is the starting number 45, and Y is the ending number 56 that it changed to. When we enter these numbers into the formula, we get:
((56-45)/45)*100 = 24.44%
Thus, the answer to the question "What is the Percent Change from 45 to 56?" is:

Two vertical angles have measures of (4x + 8) and (7x -22). What is the measure of the two angles?
Answers
Answer:
48
Step-by-step explanation:
Vertical angles are congruent
7x - 22 = 4x + 8 {Add 22 to both sides}
7x = 4x + 8 + 22
7x = 4x + 30 { subtract 4x from both sides}
7x - 4x = 30
3x = 30
x = 30/3
x = 10
4x + 8 = 4*10 + 8
= 40 + 8
= 48
7x - 22 = 7*10 - 22
= 70 - 22
= 48

Since $14 is the price after a 30% discount then $14 is 70% of the original price.
$14/70=x/100 (100% would be the original price)
1400=70x or 1400/70 = $20!
You can double check the work by taking 30% off the $20 (10% would be $2, 30% would then be $6) 20-6=14!
