p(x) = 1/2 x - 3

1) Type of function: linear function

2) Doman: all real number

3) Range: all real number

4) x-intercept:

1/2 x - 3 = 0

1/2 x = 3

x = 3 * 2

x = 6

x-intercept: (6 , 0)

5) y-intercept: x = 0; y = -3

So y-intercept: (0, -3)

6) p(x) = 1/2 x - 3

x = 0; y = -3

x = 1, y = - 5/2

x = 2 , y = - 2

x = 4, y = -1

x = 6, y = 0

x = 8, y = 1 and so on....

The output values increase as the input values increase. so it's increasing.

What is the simplified form of 15 x to the eighth power over 24 y to the fifth power divided by 4 x to the fourth power over 8 s

IRISSAK [1]

The exponent symbol when typing is ^. so I so rewrite this for you.
(15x^8 / 24y^5) / (4x^4 / 8y^2)

I assumed you meant 8y squared because you said 8 squared.

now when we divide by a fraction, we can actually multiply by it's reciprocal and get the same thing. The word reciprocal really just means flip it over. so:

(15x^8 / 24y^5) * (8y^2 / 4x^4)

let's reduce the coefficients ( the numbers in front of the x and y) to make it easier.

We have 15/24 which can be reduced to 5/8
and 8/4 which is 2/1

so:
(5x^8 / 8y^5) * (2y^2 / x^4)

multiply numerator and denominator
(10x^8y^2) / (8x^4y^5)

now reduce coeffient. 10/8 is 5/4
reduce x: x^8/x^4 is x^4
reduce y: y^2/y^5 is 1/y^3

now put together
5x^4 / 4y^3

so C

a jeweler buys gold jewelry and resells the gold to a refinery the jeweler buys gold for 1235.55 per ounce and then resells it f

weqwewe [10]

The jeweler bought it for (1235.55 * 73.5) = 90812.925...expenses
and the jeweler sold it for (1376.44 * 73.5) = 101168.34...revenue

profit = revenue - expenses
profit = 101168.34 - 90812.925 = 10355.415 rounds to 10,355.42 <==

Three numbers A. B and C are in the ratio of 12:15: 25. If sum of these numbers is 312, find the ratio between the difference of

Gala2k [10]

Answer:

The ratio of difference between B and A and the difference between C and B is 3 : 10

Step-by-step explanation:

Three numbers A, B and C are in the ratio of 12: 15 : 25

Let the rational between the numbers be x. Hence the three numbers are :

A is 12x, B is 15x and C is 25x.

Sum of these numbers is 312,

12x + 15x + 25x = 312

52x = 312

x = 6

The rational is 6. Thus the three numbers are:

A = 12x = 12 × 6= 72

B = 15x = 15 × 6 = 90

C = 25x = 25 × 6 = 150

Ratio between the difference of B and A and the difference of C and B to be calculated

Difference between B - A = 90 - 72 = 18

Difference between C - B = 150 - 90 = 60

Thus the ratio of difference between B and A and the difference between C and B is 18 : 60 or 3 : 10
