find the domain of (5y-8)/11

Answers

The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.

The domain of the function f(y) = (5y - 8)/11 is the set of all real numbers.

Dom(f(y)) = R.

What is the domain and range of a function?

Suppose we have an ordered pair (x, y) then the domain of the function is the set of values of x and the range is the set of values of y for which x  is defined.

Given a function f(y) = (5y - 8)/11.

It is a real function and the domain of the function is the set of all real numbers.

There are no restrictions as the denominator is constant and no such values of 'y' make the denominator zero.

Find X if m/angle UVY=84 degrees.

Answers

Answer:

x = 42º

Step-by-step explanation:

We know that m < UVY is equal to 84º (Given)

We know that < UVY = < SVW (Vertical Angles Theorem)

By substituting in the known values for the anges, we know that:

< UVY = < SVW

84º = 2x

Simplify the equation by dividing by 2 on both sides.

x = 42º

Hope this helps! Let me know if you have any questions!

Solution given:

<UVY=2x[vertically oppisite anglle]

x=84/2=42° is your answer

Find the slope of the line Passing through the given Points using the slope formula

Answers

Answer:

Slope is 1/2

Step-by-step explanation:

Slope Formula: m = y2 - y1/x2 - x1

We have points: (1,2) and (9,6)

m = y2 - y1/x2 - x1

m = 6 - 2/9 - 1

m = 4/8

m = 1/2

If one boy had two hats, and there were ten boys, you would simply multiply 10 by 2! that gets you 20, which is your answer!

You can think of it as instead of each boy having one hat (which would make it ten hats in total), they'd have double of ten, making it 20!

Solve for x: 7x + 15 = 38

A: 23/7
B: 53/7
C: 23
D: 53

Answers

Answer: A

Step by Step: to isolate 7x, subtract 15 from both sides of the equation. 15-15=0. 38-15=23.

now the equation is 7x=23

finally, to completely isolate the variable, divide 7 from both sides. 7x/7= x. 23/7=23/7 because it cannot be simplified further unless you want it to be a decimal.

so the answer is A, 23/7

Elena bought 8 tokens for $4.40. At this rate: 1)How many tokens could she buy with $6.05? 2) How much do 19 tokens cost?

Answers

11 tokens.
Step-by-step explanation:
First you need to find how much each token costs.
to do this, we need to divide the cost by the number of tokens.
4.40 ÷ 8 = 0.55. So, each token costs 55 cents/ $0.55.
Next, you need to find how many tokens she can afford.
to do this, we need to divide how much money she has by the cost of each token.
6.05 ÷ 0.55 = 11. So, she can buy 11 tokens in total.

Answer: She could buy 11 tokens and 19 tokens cost 10.45

Step-by-step explanation:

divide how much money you spent by how many tokens you bought

4.40/8=0.55 x 19= 10.45

6.05/0.55=11

I hope this helps!

Answer:

b=121, a and c=59

Step-by-step explanation:

b and 121 are congruent angles, so they are equal to each other.

each side of a line equals 180 degrees, so subtracting 180-121=c gives you 59 degrees.

a and c are congruent angles so they are also equal to each other

Rebecca is distributing fidget spinners as part of her campaign for school president. she has 500 fridge my spinners to distribute in packs of 25 per teacher. write a function modeling this situation. define all unknown variables

Answers

Answer:

Y= 20

Step-by-step explanation:

From the question, Rebecca has 500 fridge my spinners to distribute in packs of 25 per teacher, we can denote the number of this teacher with "Y" then for her to distribute those 500 fridge in packs of 25 per teacher, then we can say (25× Y)= 25Y ,since she has 500 fridge in total to distribute then we can write a write a function modeling this situation as

25Y=500

where Y is the number of teacher

Make Y subject of the formula we have

Y= 500/25

Y=20

Answer:

25x=500 or x=20

Step-by-step explanation:

__

Well Rebecca have 500 fidget spinners so you put that  on one end and let x be the number of teachers if you have 25 fidget spinners per teacher you need to multiply 25 by the number of teachers or x to find out so the equation will look like this: 25x=500

If you want to simplify you divide by 25 into both sides which are 20

David loves to cook! He knew 21 recipes before starting cooking school and he learns 2 recipes
every 1 one week. An equation to represent that is y = 21 + 2x where x represents number of
weeks and y represents number of recipes.
His friend Sarah believes that if he attends school for 10 weeks that means he knows 42 recipes.
Explain if she is correct.

Answers

Answer:

Sarah is incorrect.

Step-by-step explanation:

By plugging 10 in as 'x' to the equation, we get y=21+(2*10). 2 x 10 is 20, and 20 + 21 is not 42 - it's 41. So, Sarah is incorrect.

Answer:

Sarah is not correct because if David already knows 21 recipes and learns 2 recipes per week, then he will know only 41 recipes after 10 weeks, not 42.

Step-by-step explanation:

To see if Sarah is correct, let's replace the y in the equation with 42 and the x with 10:

y = 2x + 21

42 = 2(10) + 21

42 = 20 + 21

42 [tex]\neq[/tex] 41

Sarah is wrong.

longest side must be less than the sum of the legnths of the other 2 sides


if we assume that 7 is longest then missing side is x so
3+x>7
minus 3
x>4
whole number to satisfy is
x=5

if we assume the missing side is the largest
3+7>x
10>x
x is 9 at most


if the third side is not the longest side, it can be 5 at minimum
if the third side is the longest side, it can be 9 at max

so the third side can be 5,6,7,8,9 ft

A study compared the number of years of education a person received and that person's yearly salary. It was determined that the relationship between these two quantities was linear and the correlation coefficient was 0.91. Which conclusion can be made based on the findings of this study?

Answers

Answer:

Salary earned increases as the number of years of education earned increases.

Step-by-step explanation:

Given that the correlation between the number of years of education a person receive and his yearly salary yields a linear relationship with a correlation Coefficient of 0.91, this shows that a strong positive relationship exists between the two measured quantities, this is deduced by the positive nature of the correlation Coefficient value obtained and the fact that the value of the Coefficient is close to 1. Hence, salary earned increases as the number of years of education increases and Vice versa.
