Use the point-slope formula: y-2 = 1(x-1), or y-2 = x-1, or y = x + 1 (answer)
Answer:
d.
Step-by-step explanation:
To convert a root to a fraction in the exponent, remember this rule:
![\sqrt[n]{a^{m}}=a^{\frac{m}{n}}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Ba%5E%7Bm%7D%7D%3Da%5E%7B%5Cfrac%7Bm%7D%7Bn%7D%7D)
The index becomes the denominator in the fraction. (The index is the little number in front of the root, "n".) The original exponent remains in the numerator.
In this question, the index is 4.
The index is applied to every base in the equation under the root. The bases are 16, 'x' and 'y'.
![\sqrt[4]{16x^{15}y^{17}} = (\sqrt[4]{16})(\sqrt[4]{x^{15}})(\sqrt[4]{y^{17}}) = (2)(x^{\frac{15}{4}}})(y^{\frac{17}{4}}) = 2x^{\frac{15}{4}}}y^{\frac{17}{4}}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B16x%5E%7B15%7Dy%5E%7B17%7D%7D%20%3D%20%28%5Csqrt%5B4%5D%7B16%7D%29%28%5Csqrt%5B4%5D%7Bx%5E%7B15%7D%7D%29%28%5Csqrt%5B4%5D%7By%5E%7B17%7D%7D%29%20%3D%20%282%29%28x%5E%7B%5Cfrac%7B15%7D%7B4%7D%7D%7D%29%28y%5E%7B%5Cfrac%7B17%7D%7B4%7D%7D%29%20%3D%202x%5E%7B%5Cfrac%7B15%7D%7B4%7D%7D%7Dy%5E%7B%5Cfrac%7B17%7D%7B4%7D%7D)
To find the quad root of 16, input this into your calculator. Since 2⁴ = 16,
= 2.
For the "x" and "y" bases, use the rule for converting roots to exponent fractions. The index, 4, becomes the denominator in each fraction.
![2x^{\frac{15}{4}}y^{\frac{17}{4}}](https://tex.z-dn.net/?f=2x%5E%7B%5Cfrac%7B15%7D%7B4%7D%7Dy%5E%7B%5Cfrac%7B17%7D%7B4%7D%7D)

Answer:
D
Step-by-step explanation:
Answer: No, the equation is not correct
Step-by-step explanation:
Victor has saved $89.25 for a bicycle that costs $129.85. To get the remaining amount that is needed to complete the bicycle, we subtract the amount saved by Victor from the total amount. This will be:
= $129.85 - $89.25
= $40.6
The amount remaining is $40.6
The equation written by Victor is
= $89.25 + $129.85
= $219.1
The equation written by Victor is not correct. The correct equation is:
= $129.85 - $89.25 = $40.6
