Answer: First option.
Step-by-step explanation:
Given the following equation provided in the exercise:
![\sqrt[3]{x+8}=-4](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx%2B8%7D%3D-4)
You can follow the steps indicated below in order to find the solution of this equation:
1. Cubing both sides of the equation, you get:
![(\sqrt[3]{x+8})^3=(-4)^3\\\\x+8=-64](https://tex.z-dn.net/?f=%28%5Csqrt%5B3%5D%7Bx%2B8%7D%29%5E3%3D%28-4%29%5E3%5C%5C%5C%5Cx%2B8%3D-64)
2. Finally you must subtract 8 from both sides of the equation:
![x+8-8=-64-8\\\\x=-72](https://tex.z-dn.net/?f=x%2B8-8%3D-64-8%5C%5C%5C%5Cx%3D-72)
You can notice that this solution matches with the first option.
Answer:
46 Iris Blooms
Step-by-step explanation:
Multiply 40 * .15 (.15 is 15% as a decimal)
You should get 6
Add 6 to 40 and get 46
To change from percent to decimal, move the decimal place to the left two times. In this case the decimal is after the 75. so the decimal is .75 To write .75 as a fraction put 75/100 because it is in the hundredths place. Reduce by dividing both parts by 25. the fraction is 3/4
Hope that helped! if you don't get it ask and ill re explain!
Slope formula
y2-y1/x2-x1
1 = x1
-7 = y1
3 = x2
-21 = y2
Plug in the given values into their corresponding spot in the formula:
-21 - (-7) / 3 - 1
-21 - (-7) is the same as -21 + 7
-21 + 7 is the same as 7 - 21
7 - 21 = -14
3 - 1 = 2
-14/2
-14 divided by 2 = -7
The slope is -7
