A student is attempting to write the statement below as an equation. Which of the following statements best applies to the sample mathematical work? Statement: the product of a number and 2 is equal to the difference between that number and 4 Work: (1) Let x be the unknown quantity. (2) The phrase “the product of a number and 2” results in 2x. (3) The phrase “the difference between that number and 4” results in x – 4. (4) Set the values from step 2 and step 3 equal. A. The interpretation in step 2 is incorrect or invalid. B. The interpretation in step 3 is incorrect or invalid. C. The interpretation in step 4 is incorrect or invalid. D. The interpretation is correct as shown.

16

step-by-step explanation:

2 x 40 = 80

80/5

= 16

a) t'(-3, 6) and v'(0, 3)  

step-by-step explanation:

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
