Answer:
(20,-7)
Step-by-step explanation:
x+2y=6
x = 6-2y
3x+8y=4
3(6-2y)+8y=4
18-6y+8y=4
2y=-14
y = -7
x=6-2(-7)
x = 20
Answer:
x=13
Step-by-step explanation:
![g(x)=-4\\](https://tex.z-dn.net/?f=g%28x%29%3D-4%5C%5C)
Therefore, substituting the value in the equation
![g(x)=\sqrt{x+3} -8\\=>-4=\sqrt{x+3}-8\\ =>-4+8=\sqrt{x+3} \\=>4=\sqrt{x+3}\\](https://tex.z-dn.net/?f=g%28x%29%3D%5Csqrt%7Bx%2B3%7D%20-8%5C%5C%3D%3E-4%3D%5Csqrt%7Bx%2B3%7D-8%5C%5C%20%3D%3E-4%2B8%3D%5Csqrt%7Bx%2B3%7D%20%5C%5C%3D%3E4%3D%5Csqrt%7Bx%2B3%7D%5C%5C)
Squaring both sides,
![=>4^{2}=\sqrt{(x+3)} ^{2}\\=>16=x+3 \\=> x=16-3\\\\=>x=13](https://tex.z-dn.net/?f=%3D%3E4%5E%7B2%7D%3D%5Csqrt%7B%28x%2B3%29%7D%20%5E%7B2%7D%5C%5C%3D%3E16%3Dx%2B3%20%5C%5C%3D%3E%20x%3D16-3%5C%5C%5C%5C%3D%3Ex%3D13)
Answer:
hello and thank u for asking questions
the correct answers are...
A. is correct because an obtuse angle is an angle that measures over 90°
B. is incorrect because the acute angle is less than 90°
C. is correct because a reflex is "Reflex angles are angles measuring greater than 180 degrees and less than 360 degrees. The measure of a reflex angle is added to an acute or obtuse angle to make a full 360 degree circle"
D. is incorrect because if it is less than 2 but greater than 4 that does not make any sence
hopes this help pls mark brainiest and have a great and wonderful rest of your day
