Which relation is a function?

Answers

As given in the question,

the relations A , B ,C and D are set up as a table of ordered pairs.

We now test to see if each element in the domain(x-values) is matched with exactly one element in the range(y-values). If so, you have a function!

A is not a function as the domain value 0 is paired with both 3 and 4.

B is a function as for each input there is exactly one output.

C is not a function as the domain value 2 is paired with both 1 and 8.

A is not a function as the domain value 1 is paired with both -3 and 2.

Rearrange these equations :

Answers

1)b=a-4

2)d=c/4

3)m=4k+2 =2(k+1)

1.b=a-4
2.d=c:4

In a sale, normal prices are reduced by 20%The sale price was £220
Calculate the normal price of the saddle

Answers

so sale price= normal price-dicount
sale price=100%-20%=80%
therfor
220=80%of origonal price
80%
percent means parts out of 100
80%=80/100=8/10
220=8/10of origonal price
multiply both sdies by 10
2200=8 of origoal price
divide by 8
2200/8=275

origonal price=275

What are the solutions to the equation x² = 169? Choose all answers that are correct. A. 13 B. –13 C. 84.5 D. –84.5

Answers

$x^(2) = 169$

First, we need to take the square root of each side.
$x = \pm \sqrt169$

Second, we now have to find the square root of 169 to solve this. Since 13 × 13 = 169, the square root of 169 is 13. The plus-minus symbol means in this case, the solution can be -13 and positive 13. To answer your question, option A) 13, and B) -13 are the solutions to the equation.
$x = \pm 13$

Answer: $\pm13$

Answer:

The answers are A. 13, and B. -13.

Kit gathered 5 eggs when she visited her cousin's farm. Altogether, the eggs weighed 225.0 grams. She wrote down the weight of each egg, but missed the last egg. The 4 weights she recorded were 45.07 grams, 45.72 grams, 43.98 grams, and 45.02 grams. Find the weight of the missing egg. Then, to help her uncle figure out which chickens are producing the best eggs, help her order the egg weights from least to greatest. How did place value help you compare and contrast the numbers in problem 5?

Answers

add up all the numbers you have, once you get the answer to that. subtract it from 225.0 then youll have the weight of the missing egg. And you will be able to put the eggs least to greatest
