Answer:
<h2> x =
-5 - √15 or x = -5 + √15</h2>
Step-by-step explanation:
![y = x^2+10x+10\\\\y=x^2+10x+25-25+10\\\\y=(x+5)^2-15\\\\y=0\quad\iff\quad (x+5)^2-15=0\\\\(x+5)^2=15\\\\x+5=\pm\sqrt{15}\\\\x=-5-\sqrt{15}\quad or\quad x= -5+\sqrt{15}](https://tex.z-dn.net/?f=y%20%3D%20x%5E2%2B10x%2B10%5C%5C%5C%5Cy%3Dx%5E2%2B10x%2B25-25%2B10%5C%5C%5C%5Cy%3D%28x%2B5%29%5E2-15%5C%5C%5C%5Cy%3D0%5Cquad%5Ciff%5Cquad%20%28x%2B5%29%5E2-15%3D0%5C%5C%5C%5C%28x%2B5%29%5E2%3D15%5C%5C%5C%5Cx%2B5%3D%5Cpm%5Csqrt%7B15%7D%5C%5C%5C%5Cx%3D-5-%5Csqrt%7B15%7D%5Cquad%20or%5Cquad%20x%3D%20-5%2B%5Csqrt%7B15%7D)

Step-by-step explanation:
The constant of variation is found using the slope formula:
![\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
The given relation is
X : -2 , -3, -4, -5
Y : -5, -7.5,-10,-12.5
We can use any two ordered pair to find the constant of variation.
Using (-2,-5) and (-3,-7.5), we have
![m=\frac{-7.5--5}{-3--2} =\frac{-2.5}{-1} =2.5](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-7.5--5%7D%7B-3--2%7D%20%3D%5Cfrac%7B-2.5%7D%7B-1%7D%20%3D2.5)
The constant of variation is 2.5
We need to repeat this for all the options to identify the one with -2.5 as slope.
unfortunately, you did not provide the remaining options.
Answer:
With monthly compounding, the bank will calculate interest on your account just once per month. It will not update your balance on a daily basis when it calculates how much interest it owes you. Assuming that the APR is the same, accounts with monthly compounding offer a lower APY than accounts with daily compounding.
