Which pair of measurements is not equivalent?4 lb., 64 oz.
3 tons, 6,000 lb.
108 oz., 8 lb.
10,000 lb., 5 tons

Answers

If you would like to know which pair of measurements is not equivalent, you can calculate this using the following steps:

1 lb = 16 oz
1 ton = 2,000 lb

4 lb = 4 * 16 oz = 64 oz
3 tons = 3 * 2,000 lb = 6,000 lb
8 lb = 8 * 16 oz = 128 oz
5 tons = 5 * 2,000 lb = 10,000 lb

Not equivalent: 108 oz., 8 lb.

Choose the correct simplification of the expression (2x − 6)(3x2 − 3x − 6).6x3 − 24x2 + 6x + 36
6x3 − 24x2 + 6x − 36
6x3 + 24x2 − 6x + 36
6x3 − 24x2 + 6x + 12

Answers

If you would like to solve (2x - 6) * (3x^2 - 3x - 6), you can do this using the following steps:

(2x - 6) * (3x^2 - 3x - 6) = 2x * 3x^2 - 2x * 3x - 2x * 6 - 6 * 3x^2 + 6 * 3x + 6 * 6 = 6x^3 - 6x^2 - 12x - 18x^2 + 18x + 36 = 6x^3 - 24x^2 + 6x + 36

The correct result would be 6x^3 - 24x^2 + 6x + 36.

Answer:

Option A is correct.

Correct simplification of the given expression = 6x^3-24x^2+6x+36

Step-by-step explanation:

Given the expression: (2x-6)(3x^2-3x-6)

The following steps required for the multiplication of polynomials are:

  • Distribute each terms of the first polynomial to every term of the second polynomial.
  • Combine like terms

Apply these steps to the given expressions;

2x(3x^2-3x-6) -6(3x^2-3x-6)

when you multiply two terms together you must multiply the coefficient (numbers) and add the exponent.

⇒6x^3-6x^2-12x -18x^2 +18x +36

Combine like terms;

6x^3-24x^2+6x+36

Therefore, the correct simplification of the given expression is, 6x^3-24x^2+6x+36

given the graph of the line represented by the equation f(x)=-2x+b,if b is increased 4 units, the graph of the new line would be shifted 4 units 1.Right 2.up 3.left 4.down

Answers

The answer to the question if b is increased by 4 units the graph of the new line would be shifted 4 units is 2. up

Since f(x) = -2x + b, if b is increased by 4 units, we have

f(x) = -2x + b + 4

This thus shifts the fuction 4 units up, since addition of a constant to a fuction shifts its upwards.

so, if b is increased by 4 units the graph of the new line would be shifted 4 units up.

So, the answer to the question if b is increased by 4 units the graph of the new line would be shifted 4 units is 2. up

The function C(f) = (f – 32) converts a temperature, f, in degrees Fahrenheit, to atemperature, C, in degrees Celsius. Determine C(52), to the nearest degrees Celsius.

Answers


That function is incorrect.
The correct function is . . . .    C(f) = (5/9) (f - 32) .

If a Fahrenheit thermometer reads 52° ,
then a Celsius thermometer should read . . .

         C (52) = (5/9) (52 - 32) =

                        (5/9) (20)  =  (11 and 1/9)°C.
C(52)= (52-32)=20. You substitute (f) with 52
