Answer:
y ≥ x - 2 and x + 2y < 4
Step-by-step explanation:
There are two lines graphed.
The dotted line passes through (0,2) and (4,0), then:
<u>slope (m)</u>: (0 - 2)/(4 - 0) = -1/2
<u>y-intercept (b)</u>: 2
<u>equation</u>:
y = mx + b
y = -1/2x + 2
multiplying by 2 at both sides, we get
2y = -x + 4
x + 2y = 4
The inequality is x + 2y < 4 because points below this line are shaded and points on the line are not included.
The solid line passes through (0,-2) and (2,0), then:
<u>slope (m)</u>: (0 - (-2))/(2 - 0) = 1
<u>y-intercept (b)</u>: -2
<u>equation</u>:
y = x - 2
The inequality is y ≥ x - 2 because points above this line are shaded and points on the line are included.
Answer:
Choice A. √x
Step-by-step explanation:
In exponents,
![\\ \tt \: {a}^{ \frac{1}{b} } = \sqrt[b]{a}](https://tex.z-dn.net/?f=%20%20%5C%5C%20%20%5Ctt%20%5C%3A%20%20%7Ba%7D%5E%7B%20%5Cfrac%7B1%7D%7Bb%7D%20%7D%20%20%3D%20%20%5Csqrt%5Bb%5D%7Ba%7D%20)
Hence,
![\\ \tt \: {x}^{ \frac{1}{2} } = \sqrt[2]{x} \: \: \: or \: \: \: \sqrt{x}](https://tex.z-dn.net/?f=%20%5C%5C%20%20%5Ctt%20%5C%3A%20%20%20%7Bx%7D%5E%7B%20%5Cfrac%7B1%7D%7B2%7D%20%7D%20%20%3D%20%20%5Csqrt%5B2%5D%7Bx%7D%20%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20or%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20%20%5Csqrt%7Bx%7D%20)
