4x+30=40

What you would do is subtract 30 from 30 and 40 which would give you 10 and then what you would do is divide the 10 by 4 to get 2.5. Therefore X=2.5. And to check your work you would plug in 2.5 in place of X and the answer to that equation should be 10.

Write a function g whose graph represents a reflection in the y-axis followed by a translation 3 units to the right of the graph

svp [43]

Answer:

$g(x) = |x - 3|$

Step-by-step explanation:

Given

$f(x) = |x|$

Required

Translate 3 units right

The result of a right translated function is:

$g(x) = f(x - h)$

Where h is the unit of translation

$h = 3$

$g(x) = f(x - 3)$

Solve for f(x - 3)

$f(x) = |x|$

$f(x - 3) = |x - 3|$

Hence;

$g(x) = |x - 3|$

What is the mean, median, mode, and range of 8, 35, 10, 12, 14?

Ivan

answer:

mean: 15.8

median: 12

mode: no mode

range: 27

step-by-step explanation:

first know how to find each of the above and what they are
mean = (avg) add all the numbers, then divide by the number of numbers
median = the middle number from increasing order
mode = the one that repeats the most
range = the difference between the largest and smallest number

8, 35, 10, 12, 14

mean

8 + 35 + 10 + 12 + 14 = 79

there are five numbers

79 / 5 = 15.8

median

put them from smallest to largest

8, 10, 12, 14, 35

12 is the median OR the middle number

mode

no number repeat, so no mode

range

35 - 8 = 27
