Answer:

Sum of the angles of the triangle is 180°.

=> 39° + 4y + y + 11° = 180°

=> 5y + 50° = 180°

=> 5y = 180° - 50°

=> 5y = 130°

=> y = 130°/5

<h3>=> y = 26°</h3>

Answer:

Sum of the interior angles of the triangle is 180°.

According to the above problem,

4y + (y + 11) + 39 = 180 \\ 5y + 50 = 180 \\ 5y = 130 \\ y  = \frac{130}{5}  \\  \boxed{y = 26}✓

<h3><u>y=26</u><u>°</u> is the right answer.</h3>

A study was conducted to investigate the relationship between the resale price, y (in hundreds of dollars), and the age, x (in y
GaryK [48]

Answer:

a. $121.07

b. $60.9

C. $20.03

Step-by-step explanation:

From the equation given

Y=181.7-20.21x

Where y is in dollars and X is in years

a. To find the resale price after 3years we have, we substitute x=3 into the given equation.

We have

y=181.7-20.21(3)

y=181.7-60.63

y=121.07

The resale price after 3years is $121.07

b. To find the resale price after 6years we have, we substitute x=6 into the given equation.

We have

y=181.7-20.21(6)

y=181.7-120.72

y=60.98

The resale price after 3years is $60.98

C. To find the average decrease per year, we have

[(x=3)-(x=6)]/3

=(121.07-60.98)/3

$20.03

Hence the average annual decrease is $20.03

if x+3 is a factor, then -3 is a root of expression, and the remainder would be 0

calculating remainder:

-3(-3)^3+6(-3)^2+6(-3)+9=-3\cdot(-27)+6\cdot9-18+9=\\\\=81+54-9=126
