Answer:
y = -7/4x - 11
Step-by-step explanation:
formula is y = mx + b
m is the slope
b is the y intercept
y = -7/4x -11
which is the first one
Answer: The unit rate is: " 1.5 patties / bun " ;
or, write as: "1.5 patties per bun" .
_____________________________________________________
The mistake is that the problem shown is incomplete.
The "unit rate" would be the "number of patterns per [single] bun."
_________________________________________________________
30 patties/ 20 buns = 3 pattern/ 2 buns;
= (3/2) patties/ bun = 1.5 patties / bun ;
or, write as: "1.5 patties per bun" .

Answer:
The angular speed is 3,227 rad/min
Step-by-step explanation:
Remember that
1 mile=63,360 inches
step 1
Find the circumference of the wheels
The circumference is equal to
we have
substitute
step 2
we know that
The speed of the wheel is 55 mi/h
<em><u>Convert to mi/min</u></em>
55 mi/h=55/60 mi/min
<u><em>Convert to in/min</em></u>
(55/60) mi/min=55*63,360/60 in/min= 58,080 in/min
we know that
The circumference of the wheel subtends a central angle of 2π radians
so
using proportion
Find out how much radians are 58,080 inches
therefore
The angular speed is 3,227 rad/min
First of all, 2^n and 3^n are exponentials with different bases, and thus their sum cannot be simplified beyond 2^n + 3^n. In other words, these two functions cannot be combined ino one function (such as 4^n).
You may gain much more insight by graphing 2^n, 3^n and 4^n to determine whether there is truth in the given statement or not.
