To solve for x in the given equation, use natural logarithms. Getting the natural logarithms of both sides, will be ln 4^(2x) = ln 7^(x-1). This is also equal to 2x ln 4 = (x-1) ln 7. Rearranging the equation, 2x/(x-1) = ln 7/ln 4. The right side is equal to 1.4037. Thus, the value of x is -2.3539.

For each function, find f(-1), f(1), and f(3)<br> f(x)=3x-4
Anna [14]

Answer:

f(x)= 3x-4

f(-1)= 3*-1-4

f(-1)= 2-4

f(-1)= -2

f(x)= 3x-4

f(3)= 3*3-4

f(3)= 9-4

f(3)=5

f(x)= 3x-4

f(1)= 3*1-4

f(1)= 3-4

f(1)= -1

Alicia drew a pentagon with equal side lengths and equal angles. Then she added red lines of symmetry to her drawing. How many l
son4ous [18]
A pentagon is a regular polygon with five equal sides and five equal interior angles. Also, it has five vertices. To draw the line that would divide the figure equally into two, we simply have to draw a line from one vertex and then extend the line to the opposite side.

Since, there are five vertices then, she will be able to draw five.

qaws [65]

Answer:

3.10h + 2.30b ≥ 100

Step-by-step explanation:

Tammy earns $3.10 for each hour,

Let h represents hour,

So total earning for h number of hours will be 3.10h

Tammy earns $2.30 for each bushel of apples

Let b represents bushel of apples,

So total earning for b number of bushels will be 2.30b

Tammy's goal is to earn at least $100 this week

Therefore, to reach her goal the inequality will be

3.10h + 2.30b ≥ 100

Where h is the number of hour and b is the number of bushels.
