Answer:
![e^7=x](https://tex.z-dn.net/?f=e%5E7%3Dx)
Step-by-step explanation:
Given the logarithm function
![In\left(x\right)=\:7](https://tex.z-dn.net/?f=In%5Cleft%28x%5Cright%29%3D%5C%3A7)
For logarithmic equations,
is equivalent to
such that
and ![b\ne 1](https://tex.z-dn.net/?f=b%5Cne%201)
In current case:
![b=e\:](https://tex.z-dn.net/?f=b%3De%5C%3A)
![\:x=x](https://tex.z-dn.net/?f=%5C%3Ax%3Dx)
![\:y=7](https://tex.z-dn.net/?f=%5C%3Ay%3D7)
Substituting the values of
and
into the equation ![b^y=x](https://tex.z-dn.net/?f=b%5Ey%3Dx)
![e^7=x](https://tex.z-dn.net/?f=e%5E7%3Dx)
<u><em>Answer:</em></u>
Dory biked 143 miles last month
<u><em>Explanation:</em></u>
Assume that Karly biked x miles last month
We are given that Dory biked 11 times as many miles as Karly did
<u>This means that:</u>
Dory biked 11x miles last month
<u>Now, we are given that:</u>
Together they biked a total of 156 miles
<u>Therefore:</u>
156 = x + 11x
156 = 12x
x = 13
<u>Based on the above:</u>
Karly biked x miles = 13 miles
Dory biked 11x miles = 11*13 = 143 miles
Hope this helps :)
Look at the shaded areas and then read A. A rectangle has 2 sets of parallel lines (as these two figures do) and 1 right angle somewhere. These two shaded regions do not have 1 right angle.
B: B is not correct because the shaded figures have 2 sets of 2 equal lines. A rhombus has 4 equal lines.
C: Not true either. The lines have 2 sets of parallel lines. Trapezoids have only 1 set.
D. D is true
E. E is true.
Perhaps you are not supposed to consider what the figures look like. I don't know how to answer the question. You likely got the same answers I did. Any chance you copied the wrong diagram?
