Answer: Day 9
Explanation:
480 - 40t = 140
340 = 40t
t= 8.5
The answer is by the end of the day, so it is Day 9.
Okay the first one is what u did lol
Answer:
Step-by-step explanation:
slope intercept form is y = mx + b
You need to solve the equation for y. First, subtract 3x from both sides since it is a positive 3x.
3x - 3x + 12y = -8 - 3x
rewrite the equation
12y = -3x - 8
divide all terms by 12
12y/12 = -3x/12 -8/12
Simplify the fractions
No its not a function :)
<span>to find the inverse function first expand those brackets </span>
<span>you'll get </span>
<span>f(x)= x^2 - 2x^2 - 2x^2 = 4x^2 </span>
<span>f(x)= x^2 - 4x^2 + 4x^2 </span>
<span>f(x)= x^2 or y=x^2 </span>
<span>to find the inverse, swap x and y around. then make y the subject again </span>
<span>y=x^2 </span>
<span>x=y^2 </span>
<span>Root of x=y </span>
<span>now put -1 into x </span>
<span>it wont work because roots cannot have negative numbers </span>
<span>answer is no</span>
40-6=34 so he got 34/40 correct. 34/40= 85% so thats like a B...
