Answer:

Step-by-step explanation:

10y2 - 17y + 12 = y + 16

10y2 - 17y + 12 - 16 = y

10y2 - 17y - 4 = y

10y2 -17y - y -4 = 0

10y2 -16y - 4 = 0

Now put formula

x = -b +- (square root) b2 - 4ac

a = 10 b= -16 c= -4

y = -(-16) +- (square root) -16 - 4 (10) (-4)

2(10)

y = 16 +- (square root) -16 - 400

y = 16 +- (square root) -416

y = 16 +- 20.396

Now this +- is the plus minus thingy in which two answers come

The first we will do is +

16 + 20.396 16 - 20.396

20 20

= 1.8198 = -0.2198

Can someone please help

Sloan [31]

Answer:

Step-by-step explanation:

an = a1 + (n-1)d

a_n = the nᵗʰ term in the sequence = 10

a_1 = the first term in the sequence = 5

d = the common difference between terms = 4

a10 = 5 + (10-1)4

a10 = 5 + (9)4

a10 = 5 + 36

a10 = 41

Eva8 [605]

Answer:

Divide both sides by -1/3, Apply distributive property, add 1/3 to both sides

Step-by-step explanation:

If its confusing just replace -1/3 with a simple number such as -1, to make it make sense.

Using Triangle Similarity Theorems (6)

Fantom [35]

Answer:

DC = 3

Step-by-step explanation:

Based on triangle similarity theorem, we would have the following equation:

$\frac{AD}{AC} = \frac{AE}{AB}$

Plug in the values

$\frac{9}{9 + DC} = \frac{12}{12 + 4}$

$\frac{9}{9 + DC} = \frac{12}{16}$

$\frac{9}{9 + DC} = \frac{3}{4}$

Cross multiply

3(9 + DC) = 9×4

27 + 3DC = 36

Subtract 27 from each side

3DC = 36 - 27

3DC = 9

Divide both sides by 3

DC = 9/3

DC = 3

Answer:

B. 4200

Step-by-step explanation:

A suitable calculator can add the terms for you. (See attached)

The first term is 69, and the common difference is 75-69 = 6. The general term is ...

an = a1 +d(n -1)

an = 69 +6(n -1)

Then the 28th term is ...

a28 = 69 +6(27) = 231

The average term is (a28 +a1)/2 = (231 +69)/2 = 150.

The sum is the number of terms multiplied by the average term:

sum = 28×150= 4200
