Answer:
(x) = 
Step-by-step explanation:
let y = f(x) and rearrange making x the subject, that is
y = 5x + 4 ( subtract 4 from both sides )
y - 4 = 5x ( divide both sides by 5 )
= x
change x to
(x) and y back to x, thus
(x) = 
Answer:
the length is (1,3
Step-by-step explanation:
the length is 3,1
Answer: 2.1
Step-by-step explanation:
3.4 - 2.8d + 2.8d - 1.3
add the variables together and the coefficients or add the d's with d's and 3.4 with 1.3
= 3.4 - 1.3 = 2.1
=2.8d - 2.8d = 0
The final answer would be 2.1

Greetings!</h2>
Answer:
It will take them 18 hours.
Step-by-step explanation:
To find the answer of this, you must first multiply the amount of people by the time:
6 * 15 = 90
Then to find the time it takes 5 workers, divide this by 5:
90 ÷ 5 = 18
So it will take them 18 hours!

Because this equation is in slope-intercept form, we can tell exactly how it will look by checking out 3 key points.
Leading coefficient: negative, or positive.
In this case, the leading coefficient is positive, which means that the slope will be going from bottom left to upper right.
Leading coefficient = slope
In this case, the slope is 4, or 4/1, so it will be at a steep incline.
Value of constant = y-intercept.
In this case, the y-intercept is -2, which will help us narrow down our choice.
<h3><u>After reviewing the three answer choices, the most likely selection will be A, as it seems to have a slope of 4, it is positive, and it has a y-intercept of -2.</u></h3>
