Answer:
x can be replaced by 8 and -8
Step-by-step explanation:
Given : 1: x = x:64
We have to find the value of x,
Consider 1: x = x:64
This is same as writing,
Taking square root both sides, we have,
We know 
Thus, x has two values x = 8 and x = -8
the equation of the line is
let's create a system of equations
so, the equation of the line is

Answer:
Step-by-step explanation:
you need to turn the second y equation into the correct format, so it needs to be y=. Subtract the 1 from the left side and but it on the right side. Your equation should y=3x-1. To graph this on paper, you would go 1 down on the y axis, then rise (go up) 3 and run ( go over) one.on a calculator plug it into the y1 function and y2 function and then press graph.
Add the following polynomials:
All polynomials are already ordered according to their degree (exponent), and therefore you can just add straight down in columns.
For x3: 2 + 1 - 3 = 0
For x2: -4 + 6 + 2 = 4
For x: 6 - 8 -4 = -6
Constants: -3 + 12 - 7 = 2
The answer is:
4x^2 - 6x + 2
