Answer:
x = √2
Step-by-step explanation:
A graph indicates the only solution is near x=√2.

Square both sides, separate the radical and do it again.
Now, we can put this polynomial equation into standard form and factor it.
The original equation requires that we restrict the domain of possible solutions. In order for the radicals to be non-negative, we must have x ≥ 4/3. In order for the left side of the equation to be non-negative, we must have x ≤ 2. So, the only potential solutions will be in the interval [4/3, 2].
The only values in the above list that match this requirement are {√2, 2}. We know that the right side of the equation cannot be zero, so the value x=2 is also an extraneous solution.
The only solution is x = √2.

For solving higher-degree polynomials, I like to use a graphing calculator to help me find the roots. The second attachment shows the roots of the 6th-degree polynomial. They can help us factor the equation. (There are also various machine solvers available that will show factors and roots.)
Answer:
Neither of the answer choices are the y-intercept. The y-intercept in (0,7)
Step-by-step explanation:
The y-intercept is point in which a line or function crosses the y-axis.
Answer:
The length of the hypotenuse is 17.
Step-by-step explanation:
I found this out by doing:
15 x 15 = 225
8 x 8 = 64
225 + 64 = 289
Hope this helps you! :)
3x+y=-5
12x+5y=27
Let y =-5-3x
Insert y into equ.2
12x+5(-5-3x)=27
12x-25-15x=27 den rearrange
-3x=2 den x =-2/3
Den put xinto equ 1
3(-2/3)+y=5
-2+y=5(collect like terms)
Y =7
