Answer:
=−1/2
Step-by-step explanation:
You have to find the inverse of the function, then plug in -25 to that.
So:
First replace y with x and x with y
x=4(y+8)^2 - 9
Solve for y
x + 9 = 4(y+8)^2
(x + 9)/4 = (y+8)^2
Here square root both sides
sqrt((x + 9)/4) = y + 8
Subtract 8 from both sides
y = sqrt((x + 9)/4) - 8
Now plug in -25 in this equation
y = sqrt((-25 + 9)/4) - 8
solve
y = sqrt((-16 / 4)) - 8
Here, there is a negative number under the square root sign. So, -25 cannot be in the domain and the answer is D.
Answer:
The options that have two angles, which are A and D prove both triangles to be similar.
Step-by-step explanation:
The postulate AA is exactly what it sounds like, and you can find the two angles, which will prove the similarity of two triangles sharing those two angles.
The reason being is if two angles are the same between the two triangles, the third can't be different.
Answer:
option 1
Step-by-step explanation:
- we can easily rule out option 2, since 1/25 would not come out to $25 each day.
-we can rule out options 3 and 4 since it was not $75 each day and not $1 for 150 days.
<em>-we can conclude that the correct answer is option 1, 25/1, because if we divide that, we get $25, the amount each day spent.</em>
