consider the following function. f(x)=4x+7. Place the steps for finding f-1(x) in the correct order (photo)

Finger [1]

Step-by-step explanation:

f(x)=4x+7

y = 4x+7

4x = y-7

x = (y-7) /4

the correct answers are:

=> f`¹(x) = (x-7) /4 (a)

=> x - 7 = 4y (e)

=> (x-7) /4 = y (f)

=> x = 4y +7 (g)

Can someone solve Pythagorean theorem

Ad libitum [116K]

Answer:

48 units

b= 48 units

Step-by-step explanation:

pythag is $a^2+b^2=c^2$

we have a and c

so substitute them in

$14^2+b^2=50^2$

now you can solve

$196+b^2=2500$

subtract 196 from both sides

$b^2=2500-196$

subtract

2500 - 196 = 2304

$b^2=2304$

solve for the square root

square root of 2304= 48

therefore b= 48 units

The dot plot shows the number of visitors. Determine the median of the data set.

liubo4ka [24]

Answer: C) 62

Step-by-step explanation:

Median is the middle value of a sorted (in an order) data.

Total number of dots n=15 (odd)

Median = value denoted by middle number

i.e . Median = $\dfrac{n+1}{2}^{th}\text{term}$

i.e . Median = $\dfrac{15+1}{2}^{th}\text{term}$

i.e . Median = $8^{th}\text{term}$

i.e. Median= Value denoted by 8th dot = 62

Hence, the median of the data set. = 62

Hence, the correct option is C) 62.
