Answer:
a = 8
Step-by-step explanation:
a + 7 = 15
a + 7 - 7 = 15 - 7 Subtract 7 from both sides.
a = 8
A and b are the legs, and c is the hypotenuse.
hope this helps!
In the case of exponential functions, the graph is shifted when a constant is added to the exponent of the constant. The original equation, f(x) is:
f(x) = (1/2)ˣ
Now, when horizontal shifting is occurring, the equation is:
y = Cˣ⁺ᵃ
If a is positive, the graph shifts to the lefts and the shift is equal to a units. If a is negative, the graph shifts to the right and the shift is equal to a units. Therefore, to shift the graph 3 units to the left:
g(x) = (1/2)⁽ˣ⁺³⁾
The correct answer is B.

We write the kinematic equations for each one.
We have then:
For Janene:
r = (9) * t
For Emily:
r = (8.25) * (t-16)
Equating both equations:
(9) * t = (8.25) * (t-16)
t (9-8.25) = - 132
t = -132 / (9-8.25)
t = -176
We observe that time is negative, which physically does not make sense.
This means that Emily does NOT reach Janene.
Answer:
Emily DOES NOT reach Janene
