3 0

Answer:

d

Step-by-step explanation:

a is incorrect because

20/32=10/16=5/8

b is incorrect because

10/7=1.42 and 7/10=0.7 which don't equal each other

c is incorrect because

4/6 equals 2/3 not 3/5

d is correct because,

18/48=15/40

The table shows the input and output of a function Table(input:3,4,6,11. Output:5,7,11,21) (a) Explain what makes this set of da
JulijaS [17]

Ans(a):

We know that a function can't have repeated x-values.

In given table we see that there i no repeating x-value. That's why the given table  represents function.


Ans(b):

We know that a function can't have repeated x-values.

So if in given table we see any repeating x-value then that may cause the given data set to not be a function.

like if we have 3, 4, 3, 11 in the input then it will not be a function.


Ans(c):

we can use two points say (3,5) and (4,7) to find the linear equation of the form y=mx+b

slope is given by

m=\frac{y_2-y_1}{x_2-x_1}=\frac{7-5}{4-3}=2

Noow plug value of m=2 and any point say (3,5) into y=mx+b

5=2(3)+b

5=6+b

-1=b

now plug m=2 and b=-1 in y=mx+b, we get y=2x-1

Hence required equation in function notation can be written as

f(x)=2x-1.


Now to prove that above function is correct, we just graph the given points from table and the obtained function.

We see that points lie on the grpah of f(x)=2x-1.

Which proves that our equation is correct.

Studentka2010 [4]

Answer:

x = 0

Step-by-step explanation:

5x=29x

Subtract 5x from each side

5x-5x=29x-5x

0 = 24x

Divide each side by 24

0/24 =24x/24

0 = x
