Ann [662]

<u>Corrected Question</u>

In the year 2009, the cost of a flat screen television can be  modeled by the equation C = -10t^2 + 500 where t is the  number of years since 2009. Factor this cost polynomial.

Answer:

C=10(50-t^2)

Using express exponents, you write C=10(50-t^2)

Step-by-step explanation:

To factor the cost polynomial, C=-10t^2+500, we follow these steps.

Step 1: Determine the greatest common divisor of the terms in the polynomial

The terms in the polynomial are -10t^2$ and 500

The greatest common divisor of -10t^2$ and 500 is 10.

Step 2: Factor the polynomial by dividing each of the terms with the greatest common divisor obtained above.

C=10\left(\dfrac{-10t^2}{10} +\dfrac{500}{10}\right)\\C=10(-t^2+50)\\$We can rewrite this as \\C=10(50-t^2)

Answer: 7 1/12

B.

Step-by-step explanation:

Rewriting our equation with parts separated

=1+1/4+5+5/6

Solving the whole number parts

1+5=6

Solving the fraction parts

1/4+5/6=?

Find the LCD of 1/4 and 5/6 and rewrite to solve with the equivalent fractions.

LCD = 12 3/12+10/12= 13/12

Simplifying the fraction part, 13/12,

13/12=1 1/12

Combining the whole and fraction parts

6+1+1/12 = 7 1/12

What is the general form of the equation of the line shown?
OleMash [197]
I think the correct answer would be A. 3x+y-3=0
because if you were to change it to slope intercept form, it would be y=-3x+3, which would be the equation for the line on the graph.
