Answer: just divide 44.88 by 12 so you will get 3.74
Step-by-step explanation:
Answer:
x=3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
4x+x+3=18
(4x+x)+(3)=18(Combine Like Terms)
5x+3=18
5x+3=18
Step 2: Subtract 3 from both sides.
5x+3−3=18−3
5x=15
Step 3: Divide both sides by 5.
5x/5 = 15/5
x=3
To model half-life, use the formula
. Here,
is the amount remaining after a length of time
.
is the amount that you start with.
is the half-life. You plug in 50 for
, 10 for
, and 25 for
. You get
.
Answer:
the function is EVEN because f(x)= f(-x)
Step-by-step explanation:
Key to find if a function f(x) is even or odd is to replace the x with -x
if the results comes out to be f(x) then it is even function
if the results comes out to be -f(x) then it is odd function
where as graphically even f(x) will be symmetric around the y-axis and odd f(x) will be symmetric around the origin.
In given case f(x)=7
if we replace x with -x in above equation then results is 7
f(-x)= 7
hence f(x)= f(-x) = 7

Answer:
y= 1.5x + 2.5
Step-by-step explanation:
So slope intercept form is y= mx + b.
y is the number of minutes, so that will be on the left of the equal sign, not part of the math side of the actual equation, because it's the answer.
1.5x is the mx part because it's 1.5 minutes for each extra patty. So that would explain the x attached to it. so for each extra patty you add, that's what x would be.
The + 2.5 at the end, is just the time for the initial patty.
Hope this helps and is easy to understand! :)
