Answer:
z=13
Step-by-step explanation:
Ok we are to solve for z from the given equation
2z=26
It's like making z the subject of formula
We will be able to think fast on how to make z the subject of formula from the equation
To make z the subject of formula we will have to divide both sides by 2
z=13
Therefore the value of z is 13
To solve this kind of question you must be to think on ways to eliminate the number behind the required number
Hope you understand
Answer:

Step-by-step explanation:
1. you distrubute the -4 to the -2x and +7.
2.you combine like terms.
3.you get X in one side of the equation.
4.You divide 1 by 6.
The interest is 11.62% compounded monthly. Converting this to an effective rate:
i = (1 + 0.1162/12)^12 - 1
i = 0.1226
We use this formula to solve the problem:
455.96 = (23860(1.0811) + 1695 + 228 - C) [0.0811(1+0.0811)^3]/[(1+0.0811)^3 - 1]
Solving for C
C = 4413.13
The cost of her car was $4,413.13.
your answer will be f(x)=113−kx,f(−3)=121
