Answer:
-5 =x
Step-by-step explanation:
3^(x-1) = 9^(x+2)
Replace 9 with 3^2
3^(x-1) = 3^2^(x+2)
We know that a power to a power means the powers are multiplied
a^b^c = a^(b*c)
3^(x-1) = 3^(2x+2)
When the bases are the same, the powers have to be the same
x-1 = 2x+4
Subtract x from each side
x-x-1 =2x-x+4
-1 =x+4
Subtract 4 from each side
-1-4 =x+4-4
-1-4 = x
-5 =x
Answer:
the slope is -4.
Step-by-step explanation:
To find the slope, look at the number in front of the x which is known as the coefficient. Hope this helps :)
Answer:
262 miles
Step-by-step explanation:
251.55 - 20.99 = 230.56

Answer:
x=42°
Step-by-step explanation:
We know that 2 of the legs are congruent, so the angles opposite them will be congruent.
The angles of a triangle add up to 180°
This can be represented by
