Answer:
C) y = 2|x - 3| - 1
Step-by-step explanation:
Point slope form: y = a(x - h) + k
The slope (a) is 2
The vertex (h, k) is (3, -1)
plug these values into the equation:
y = 2|x - 3| - 1
Answer:
30 oranges
Step-by-step explanation:
2 apples : 5 oranges
12 apples : 30 oranges
because 12 apples is 6 times the original ratio, so we multiply the 5 oranges by 6 too.
Answer:
![a^{\frac{1}{2}}b^{\frac{1}{2}}](https://tex.z-dn.net/?f=a%5E%7B%5Cfrac%7B1%7D%7B2%7D%7Db%5E%7B%5Cfrac%7B1%7D%7B2%7D%7D)
Step-by-step explanation:
Given:
The expression in radical form is given as:
![\sqrt{ab}](https://tex.z-dn.net/?f=%5Csqrt%7Bab%7D)
We need to express this in fractional exponent form.
We know that,
![\sqrt a=a^{\frac{1}{2}}](https://tex.z-dn.net/?f=%5Csqrt%20a%3Da%5E%7B%5Cfrac%7B1%7D%7B2%7D%7D)
Also, ![\sqrt{ab}=\sqrt a\times \sqrt b](https://tex.z-dn.net/?f=%5Csqrt%7Bab%7D%3D%5Csqrt%20a%5Ctimes%20%5Csqrt%20b)
Now, clubbing both the properties of square root function, we can rewrite the given expression as:
![\sqrt{ab}=\sqrt a \times \sqrt b\\\\\sqrt{ab}=a^{\frac{1}{2}}\times b^{\frac{1}{2}}\\\\\therefore \sqrt{ab}=a^{\frac{1}{2}}b^{\frac{1}{2}}](https://tex.z-dn.net/?f=%5Csqrt%7Bab%7D%3D%5Csqrt%20a%20%5Ctimes%20%5Csqrt%20b%5C%5C%5C%5C%5Csqrt%7Bab%7D%3Da%5E%7B%5Cfrac%7B1%7D%7B2%7D%7D%5Ctimes%20b%5E%7B%5Cfrac%7B1%7D%7B2%7D%7D%5C%5C%5C%5C%5Ctherefore%20%5Csqrt%7Bab%7D%3Da%5E%7B%5Cfrac%7B1%7D%7B2%7D%7Db%5E%7B%5Cfrac%7B1%7D%7B2%7D%7D)
So, the given expression in fractional exponents form is
.
The perimeter is 17 units! :D
Since the line is parallel, the same coefficients can be used for x and y. The constant on the right needs to change so that the given point will satisfy the equation.
... 5x - 4y = 5(-8) -4(2) = -40 -8 = -48
Your equation is
... 5x -4y = -48
