An equation is shown below:
6(2x - 11) + 15 = 3x + 12
Part A: Write the steps you will use to solve the equation, and explain each step. (6 points)
Part B: What value of x makes the equation true? (4 points)

Answers

x = 7
6(2x-11)+15=3x+12
distribute the 6:
12x-66+15=3x+12
add -66 and 15:
12x-51=3x+12
subtract 3x from both sides:
9x-51=12
add 51 to both sides:
9x=63
divide 9 from both sides:
x=7

X=7 hope this helps

Write a function rule for "The output is two more than one-fourth of the input ."

Answers

Answer:

y=(x/4)+2

Step-by-step explanation:

let y be the output and x be the input. So,

y=(x/4)+2

The function rule for " The output is two more than one-fourth of the input " is y = 2 + (1/4)x.

What is function?

A function is a relation between a dependent and independent variable. We can write the example of functions as -

y = f(x) = ax + b

y = f(x, y, z) = ax + by + cz

Given is to find the function rule for "The output is two more than one-fourth of the input."

The given mathematical statement is - "The output is two more than one-fourth of the input."

Assume the input to be {x} and the output be {y}. So, we can write that -

(output) = (two) + (1/4)(input)

y = 2 + (1/4)x

Therefore, the function rule for " The output is two more than one-fourth of the input " is y = 2 + (1/4)x.

What is 100% more than $50? (P.S. this is 20 pts and more if u get brainliest.)

Explanation:
100% of 50 is 50, so 100% more would be the original 50, plus another 50, = 100

$100. 100% of 50 is 50. So you add 50 plus 50. Then you get an answer of 100.

Suppose you have;

g=4z+14

z=4x-42^2

what is g in terms of x

Answers

g= -16x^2 +16x + 14 (going based on the picture, not your typing)

First solve the first equation for z:
g-14=4z
(g-14)/4=z

Then plug that in for z in the second equation and solve for g:
(g-14)/4 = 4x-4x^2
g-14=16x-16x^2

g= -16x^2 +16x + 14
