Answer:
C. [tex]x=\frac{3}{2} , y=\frac{1}{2}[/tex]
Step-by-step explanation:
Both of the equations would equal to one another since they're both solving for "y".
Steps: Plug in x into one of the equation:
[tex]-x+2=3x-4[/tex] [tex]y=3(\frac{3}{2} )-4[/tex]
[tex]-3x+4[/tex] [tex]-3x+4[/tex] [tex]=\frac{9}{2} -4[/tex]
------------------------ [tex]=4.5-4[/tex]
[tex]-4x+6=0[/tex] [tex]y=0.5 or \frac{1}{2}[/tex]
[tex]-6[/tex] [tex]-6[/tex]
------------------
[tex]\frac{-4x}{-4} =\frac{-6}{-4}[/tex]
[tex]x=\frac{3}{2}[/tex]
[tex]x=\frac{3}{2} , y=\frac{1}{2}[/tex]

[tex] x = 4 \sqrt{3} [/tex]
Step-by-step explanation:
By Pythagoras Theorem:
[tex] {x}^{2} = {( \sqrt{8 \times 4}) }^{2} + {(4)}^{2} \\ \\ {x}^{2} = {( \sqrt{32}) }^{2} + {(4)}^{2} \\ \\ {x}^{2} = 32 + 16 \\ \\ {x}^{2} = 48 \\ \\ x = \sqrt{48} \\ \\ x = \sqrt{ {4}^{2} \times 3} \\ \\ x = 4 \sqrt{3} [/tex]

ralph and edie each solved the equation (x-7)^2 - 100 = 0. ralph says the correct answer is x= -3. who is correct? how do you know?
Answers
Explanation:
X = -3
(-3-7)^2-100 = 0
You do parentheses first according to PEMDAS so:
-3-7 = -10
(-10)^2-100 = 0
Next, you do exponents
-10^2 or -10 * -10 = 100
Finally, you subtract
100-100 = 0

A

O
B

non-linear function that decreases then increases
D
non-linear function that increases then decreases
Answers
Answer:
D
Step-by-step explanation:
I'm going to ponder a guess that the numbers shown, 0, 62, 1, 78, 2 ,etc. are part of a table. Having said that, the answers, when graphed, create a sort of parabola, meaning that the function itself is non-linear. This exterminates option A and B. Now its just a matter of seeing which way it goes, and since 78 is higher than 62, and 85 is higher than 78, it obviously increases, rather than decreases. This makes D our final answer.
