Answer:
None of the above
Step-by-step explanation:
The figure3 shows 1 side and 1 angle of one triangle congruent to 1 side and 1 angle of the other triangle. We are not shown anything else, so the answer is:
None of the above
and you can't prove the triangles congruent.
Step-by-step explanation:
The inequality which shows the relationship between the plotted points on the number line is
B. - 9 < - 7
Solve for x of first equation,
17-3=8x
14=8x
7/4 = x
x= 7/4
Put the x value in 4x+9,
4x+9 = 4(7/4) + 9 = 7+9 =16
Therefore, the value of 4x+9 is 16.

Step-by-step explanation:
Answer:
The equation is:
![3(2) ^ t=1,536](https://tex.z-dn.net/?f=3%282%29%20%5E%20t%3D1%2C536)
After ![t=9\ months](https://tex.z-dn.net/?f=t%3D9%5C%20months)
Step-by-step explanation:
This situation can be represented by an exponential growth equation of the form
![y = a (b) ^ {t}](https://tex.z-dn.net/?f=y%20%3D%20a%20%28b%29%20%5E%20%7Bt%7D)
Where a is the initial amount
b is the growth rate
t is the time in months
In this case the initial amount is $ 3. Then ![a=3](https://tex.z-dn.net/?f=a%3D3)
if she initially saves $3 and plans to double the amount she saves each month then
![b=2](https://tex.z-dn.net/?f=b%3D2)
The bike Jane wants is $1,536 at the local bike shop.
Then ![y=1,536](https://tex.z-dn.net/?f=y%3D1%2C536)
The equation is:
![3(2) ^ t=1,536](https://tex.z-dn.net/?f=3%282%29%20%5E%20t%3D1%2C536)
Now we solve the equation for t
![3(2) ^ t=1,536](https://tex.z-dn.net/?f=3%282%29%20%5E%20t%3D1%2C536)
![(2) ^ t=\frac{1,536}{3}](https://tex.z-dn.net/?f=%282%29%20%5E%20t%3D%5Cfrac%7B1%2C536%7D%7B3%7D)
![(2) ^ t=512](https://tex.z-dn.net/?f=%282%29%20%5E%20t%3D512)
![log_2(2) ^ t=log_2(512)](https://tex.z-dn.net/?f=log_2%282%29%20%5E%20t%3Dlog_2%28512%29)
![t=log_2(512)](https://tex.z-dn.net/?f=t%3Dlog_2%28512%29)
![t=9\ months](https://tex.z-dn.net/?f=t%3D9%5C%20months)
