Hello!

To solve for x you need to isolate x on one side as seen below.

kx+c=9
kx+c-c=9-c
kx=9-c
kx/k=(9-c)÷k
x=\frac{9-c}{k}

I hope this helps!

(q^4)^z= q^12 find the value of z
juin [17]

Answer:

z = 3

Step-by-step explanation:

we use the method

(x^a)^b = x^(a*b)

so

(q^4)^z = q^(4*z)

now

4*z = 12

z = 12 / 4

so

z = 3

A town has a population of 2000 and grows at 4% every year what will be the population after 15 years to the nearest whole numbe
fomenos

To begin lets say year one the population is 2,000

assume this in percent we can say that 2,000=100%

at the end of this year the population will have grown by 4% meaning that

100%+4% will be the new population =104%

but we know that 100%=2,000 so what about 104%=X?

so (104*2000)/100=2,080

So year 1 the population will have grown by 80 people amounting to 2080 people.

Now do it manually year by year until we reach the 15th year. i will help you up to year 3

2nd year= (2080*104)/100=2163.2

3rd year= (2163*104)/100=2249.728
