Slope is -10/20=-1/2
y-7=(-1/2)(x+15). answer C
Answer: e= -4
Step-by-step explanation:
2e-12=7e+8
2e-7e=8+12
-5e=20
e=<u>20</u>
-5
e= -4
Given: e^x=25step1: ㏑ e^x= ㏑ 25
step2: x㏑ e= ㏑ 5^2
step3: x=
![\frac{2In5}{1}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2In5%7D%7B1%7D%20)
step4: x=2㏑ 5<u />
The answer is 70
you can just divide 63 by 0.9 (90%)
you can use proportions to do that
5 x 0.4 = 2 and
![\sqrt{2}](https://tex.z-dn.net/?f=%20%5Csqrt%7B2%7D%20)
= 1.4142....... which is an irrational number
