The ordered pairs (1,6), (,25), (3,36), (4,49) and (5, 64) represent a function. what is a rule that represents this function?

Answers

Answer 1

Answer: I believe this is a function. I am not sure because one of the pairs only has a y value.
But the rule is there can only be one x value for one y value so for example, you can have (3.7) and (3,9) and the same for the y values.

4/11 · 10/8

Answers

4/11 * 10/8

Multiplying fractions
1) multiply the numerators: 4 * 10 = 40
2) multiply the denominators: 11 * 8 = 88
3) simplify the fraction
40/88 ⇒ 10/22 ⇒ 5/11

40 ÷ 4 = 10
88 ÷ 4 = 22

10 ÷ 2 = 5
22 ÷ 2 = 11

4/11 * 10/8 = 5/11

Solve for x
3x+1/14=2x/8

Answers

3x+(1/14)= 2x/8
24x+(4/7)=2x ( i multiplied everything by 8)
22x+4/7=0 ( i subtracted 2x to both sides)
22x= -4/7 ( i subtracted 4/7 to both sides)
x= (-4/7)/ 22
x= -2/77

$3x + (1)/(14) = (2x)/(8)$

First, you multiply everything by 8, so you get:
$8(3x + (1)/(14)) = 8( (2x)/(8))$

Then, you develop, and you get:
$24x + (8)/(14) = 2x$

You simplify $(8)/(14)$ by dividing by 2, and you get:
$24x + (4)/(7)$ = 2x

Then, you put known numbers apart (numbers without x), and unknown numbers apart (numbers with x), which means you move 2x to the other part (and it become -2x), and $(4)/(7)$ to the other part ( and it become $- (4)/(7)$ ), so you get:
$24x - 2x = - (4)/(7)$

you subtract and you get:
$22x = - (4)/(7)$

then, you move 22 to the other part, and since it's a multiplication, it become a division, so you get:
$x = ( - (4)/(7) )/(22)$

As you know, $22 = (22)/(1)$ , and dividing 2 fraction is equal to multiplying the first fraction by the inverse of the second fraction, so you get:
$-(4)/(7) * (1)/(22) = x$

You multiply and you get:
$- (4)/(154) = x$

4 and 154 have a common factor which is 2, so you divide each one by 2, and you get:
$-(4/2)/(154/2) = x$

you divide, and you get:
$-(2)/(77) = x$

So, $x = -(2)/(77)$

Hope this Helps! :D

3. 9-9=0
9 + 1=10

5. Your answer is 0

0 becuase the slope of a line is the amount of one y to another and both y's are 9 so there is no slope.
