If you're looking for the value of z, then the answer should be -5.
X=-1 is the answer. Hope that helps!
Answer:
Hi how are you doing today Jasmine
12 ^3 and 11^3 haven't got the same base so the rules of exponents do not apply.
Bases have to be the same:- for example 12^3 * 12*3 = 12 ^(3+3) = 12^6
Answer:
The equation is ![y=-4x+103](https://tex.z-dn.net/?f=y%3D-4x%2B103)
The slope is m=-4
Step-by-step explanation:
we know that
The linear equation in slope intercept form is equal to
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
where
y is the amount left in the saving account
x is the number of weeks
m is the slope or unit rate of the linear equation
b is the y-intercept or initial value
In this problem we have
The slope is equal to
--> is negative because is a decreasing function
The y-intercept or initial value is
![b=\$103](https://tex.z-dn.net/?f=b%3D%5C%24103)
substitute
![y=-4x+103](https://tex.z-dn.net/?f=y%3D-4x%2B103)
