Answer:
x = -7
Step-by-step explanation:
This is an exponential equation.
We need to take log(or ln) of both sides and use logarithm property to solve this.
So, let's take ln of both sides, so we have:
Now, we will use this property shown below to further simplify:
So, we now have:
The value of x is -7
Y=2x-1 because (y2-y1)/(x2-x1) is 10/5 which is two. Using point slope form y-y1=m(x-x1) we find y=2x+1.

Step-by-step explanation:
In other to draw a mapping diagram for the ordered pairs (1,0) (3,0) (5,4) (7,4) (9,4).
We identify the domain and range:
The domain is the set of the first coordinates of the ordered pairs.
Domain={1,3,5,7,9}
The range is the set of all the second coordinates.
Range: {0,4}
Answer:
fiction books = 4
non fiction books = 8
non fiction books are twice fiction books.
Step-by-step explanation:
let number of fiction books be X so
non fiction books will be 12-X
12X + 25(12-X) = 248
12X -25X = -53
X = 4( fiction books)
12-4 = 8 (non fiction)
Answer:
64.4
Step-by-step explanation:
In one of the trig formulas, it states sin <a/A = sin<b/B = sin<c/C
So we have in this case:
sin(70)/12 = sin x/14 Note: x is just a variable for the angle <ABC
14(sin70)/12 = sin x
sin^-1(14(sin70)/12) = x
x=64.4
