What is the domain of f for f(x)=x-3/x+2?

Answers

Answer:

(-infinity, -2) ∪ (-2, infinity)

Step-by-step explanation:

I will have to assume that you meant

f(x)=(x-3)/(x+2).  You must use parentheses to specify the order of operations in this problem.

x can take on any value except -2, at which the function is undefined.

Thus, the domain is (-infinity, -2) ∪ (-2, infinity)

Dennis is selling chocolate bars for a
fundraiser, and if he sells over $175 worth of
candy, he'll win a prize. If chocolates sell for
$2.50 a bar, and Dennis has already sold $40
worth of candy, then how many more bars does
he have to sell in order to win a prize? (Solve for x with inequalities)

Answers

Answer:

54 , 2.50x+40=175

Step-by-step explanation:

Answer:

2.5x + 40 > 175 (Dennis has to sell 55 chocolate bars)

Step-by-step explanation:

When you solve the inequality, you get...

2.5x + 40 > 175

Subtract 40 on both sides...

2.5x > 135

Divide 2.5 on both sides...

x > 54

When you substitute 54 for x in the original inequality you get...

175 > 175

Dennis needs to make more than 175 so he needs to sell 55 not 54.

Hope this helps :)

a y = 14^x
b y = -3 (17)^x
c y = 120x
d y = -275x

Answers

Answer:The given equation is of the form y = mx + b where m is the slope and b is the y-intercept.

Here, m = -14

Two parallel lines have the same slope. So, the slope of the new line will be -14.

To calculate the y-intercept substitute x=4 and y=4 in the equation.

4 = (-14)(4) + b

Solving for b, we get b = 60.

So, the new equation will be y = -14x + 60

Answers

Answer:

y=50 and x=-173/2

Step-by-step explanation:

52-2y=-48

∴-2y=-100

y=50

and 2x+3y=-23

y=50→(1)

2x+3y=-23→(2)

Putting y=50 in equation (2), we get

⇒2x+3y=-23

⇒2x+3(50)=-23

⇒2x+150=-23

⇒2x=-23-150

⇒2x=-173

⇒x=-173/2

∴y=50 and x=-173/2

Mr Singh is paid £11.70 per hour after tax is deducted.

This means that for x hours of work, his earning are given by:

[tex]E(x) = 11.7x[/tex]

a) How much does he earn if he works 5 hours?

This is E(5).

[tex]E(5) = 11.7*5 = 58.5[/tex]

b) How much does he earn if he works 10 hours?

This is E(10).

[tex]E(10) = 11.7*10 = 117[/tex]

c) He works 37.5 hours per week. How much does he earn in a week?

Least common denominator of 3/4 and 3/8

Answers

Answer:

8

6/8 and 3/8

4 = 2²

8 = 2³

LCM = 2 × 2 × 2

LCM = 8

The Least common denominator of the fraction numbers 3/4 and 3/8 is 9/24

What is least common denominator?

The least common denominator (LCD) of 3/4 and 3/8 is the smallest number that both 4 and 8 can divide into evenly.

The prime factorization of 4 is 2 x 2, and the prime factorization of 8 is 2 x 2 x 2.

Next, we list the prime factors of each denominator and identify any factors that are common to both:

4: 2 x 2

8: 2 x 2 x 2

The common factors are 2 x 2, which means that we only need to include one set of these factors in the LCD.

So, the LCD of 3/4 and 3/8 is:

LCD = 2 x 2 x 2 x 3 = 24

For 3/4, we need to multiply both the numerator and denominator by 6 to get:

3/4 = (3 x 6)/(4 x 6) = 18/24

For 3/8, we need to multiply both the numerator and denominator by 3 to get:

3/8 = (3 x 3)/(8 x 3) = 9/24
