Find the value of X in X-X³=17​

Mathematics
1 answer:
Karolina [17]3 years ago
5 0

Answer:

Step-by-step explanation:

Step1: find the interval of roots. Consider -3 and -2

f(-3) = -7

f(-2) = 18 >0

Hence, the root must be on [-3,-2]

Step2:  consider the middle point -2.5

f(-2.5) = 3.875 >0

Then, the root must be on [-3, -2.5]

Step 3: Repeat step 2 by finding the value of f at the middle point -2.75

f(-2.75) = -1.0468

Step 3: Repeat step 2 by finding the value of f at the middle point of the interval [-2.75,-2.5] which is -2.625

f(-2.625) = 1.537 >0

Step4: Repeat step 2 on [-2.75, -2.625]

Repeat step 2 until you got the root which is -2.701

Cynthia was offered two different jobs for the summer. working as a camp counselor, she will earn $15 per hour plus an additiona
Natali [406]

The value of the composite function (f - g)(x) is 5x - 25

<h3>How to determine the function (f - g)(x)?</h3>

The function definitions are given as:

f(x) = 15x + 25

g(x) = 10x + 50

The function (f - g)(x) is calculated using

(f - g)(x) = f(x) - g(x)

This gives

(f - g)(x) = 15x + 25 - 10x - 50

Evaluate the like terms

(f - g)(x) = 5x - 25

Hence, the value of the composite function (f - g)(x) is 5x - 25

Cynthia was offered two different jobs for the summer. working as a camp counselor, she will earn $15 per hour plus an additional $25 bonus. her earnings after x hours can be represented by the function f(x) = 15x + 25. working as a lifeguard, Cynthia will earn $10 per hour and an additional $50 bonus. her earnings after x hours can be represented by the function g(x) = 10x + 50. the arithmetic operation (f - g)x can be used to determine the difference in the salary Cynthia will earn working as a camp counselor instead of a lifeguard after x hours. what is the function (f - g)x?

Answer:

84

Step-by-step explanation:

x = number of girls

The total for boys is 2x * 81 and for girls it would be 90x

Therefore, the equation goes like this:

2x * 81 + 90x

Then simplify, and set to equal 3x...

3x = 252

Which is the same as

x = 84
