a. let us say that:
a = cost of phones with camera
b = cost of phones with camera and mp3
c = cost of phones without any features
b = 2 a – 35
c = a – 100
a + b + c = 525
b > a > c
b. We are given three equations with three unknowns. So
we can solve the problem.
a + (2 a – 35) + (a – 100) = 525
a + 2 a – 35 + a – 100 = 525
4 a – 135 = 525
4 a = 660
a = $165
Take into account that x represents the number of decades after 1950. Moreover, consider that -0.5x is a decrease in the values of y, each decade.
Then, you can conclude that each decade, that is, every 10 years, the shoreline reduces 0.5 feet.
Hnece, you have:
The shoreline is reduced by 0.5 foot every 10 years

Answer:
-1
Step-by-step explanation:
The remainder of n/4 is 2
n/4 represents the exponent
For example if n=6 then when we divide 6/4 the remainder is 2
if n=6 then i^6 = i^4 * i^2 = 1* (-1) = -1
The value of i^2=-1
i^2 = -i
i^4= 1
So if the remainder of n/2 =2 then it means i^2 = -1
the value of i^n =-1
Answer:
a=1
b= -6
c=48
Step-by-step explanation:
x^2=6(x-8)
x^2=6x-48
x^2-6x+48
a,b are the coefficients of x^2 and x
c is the constant value present
Therefore it is basically written as ax^2+bx+c
and comparing with the answer x^2-6x+48,
a=1, b= -6, c=48
