This is the concept of algebra, we are required to solve the given expression;
32^(2c)=8^(c+7)
this can be written as:
2^[5(2c)]=2^[3(c+7)
applying the natural logs we shall get
[5(2c)]ln2=[3(c+7)]ln2
The ln 2 will cancel on from both sides and we shall have:
5(2c)=3(c+7)
10c=3c+21
To make c the subject we begin by subtracting 3c from both sides
10c-3c=3c+21-3c
7c=21
dividing both sides by 7 we get:
(7c)/7=21/7
c=3
The answer is c=3

3(x-1)=2x+9. Solve equation
Anna11 [10]

Hello.

In order to solve this equation, we need to isolate the variable (in this case, the variable is x)

The first step is to use the Distributive Property and distribute 3:

\mathrm{3(x-1)=2x+9}

\mathrm{3x-3=2x+9}

Now, add 3 to both sides:

\mathrm{3x-3+3=2x+9+3}

\mathrm{3x=2x+9+3}

\mathrm{3x=2x+12}

Now, subtract 2x from both sides:

\mathrm{3x-2x=2x-2x+12}\\\mathrm{3x-2x=12}

\mathrm{x=12}

Therefore, the answer is

\mathrm{x=12}

I hope it helps.

Have a nice day.

Phoenix [80]

Answer:

The answer is shown in the pic.

Step-by-step explanation:

The cost model will have a fixed cost of $26.30 for 0 ≤ x ≤ 1 lb and variable cost of $4.00/lb for x > 1.

As seen on the pic, the graph will be that of the greatest integer function that is vertically stretched by a factor 4.00 & shifted 26.30 units upward.

Can someone please help me solve this, thank you so much if u help!
malfutka [58]

Answer:

  68°

Step-by-step explanation:

The triangle containing the 79° angle is isosceles. That means the other base angle is also 79°. The central angle is ...

  V = 180° -2(79°) = 22°

__

Angle X is the other acute angle in right triangle VWX, so has measure ...

  X = 90° -22° = 68°

_____

<em>Additional comment</em>

A tangent makes a right angle with the radius to the point of tangency. W is the point of tangency, so angle VWX is a right angle.

Hannah and Anthony are siblings Who have ages that are consecutive odd numbers do some of their ages is 92 which equations could
baherus [9]
Let Hannah's age be represented by h; 

Since Anthony's age is a consecutive odd number age; his age is (h+2) 

92=(h)(h+2) 
92-2=2h
90=2h
90/2=h 
45=h 

If Hannah is 45 years old, Anthony is (45+2)= 47 years old

Hope I helped :)
