A line passes through (2, -1) with slope 3.
Morgarella [4.7K]
A. y - 1 = 3x + 6
Add 1
y = 3x + 7

B. 3y + 6 = x - 1
Subtract 6, then divide by 3
3y = x - 7
y = 1/3x - 7/3

C. y - 2 = 1/3x + 1
Add 2
y = 1/3x + 3

D. y + 1 = 3x - 6
Subtract 1
y = 3x - 7

When put on a graph, D passes through (2, -1)

Answer is D.

Find the length of the third side. If necessary, write in simplest radical form.<br> 2741<br> 8
ki77a [65]

Answer:

<u>10</u>

Step-by-step explanation:

Let the missing side be 'x'.

Using Pythagorean Theorem, we can find the missing side.

  • x² + 8² = (2√41)²
  • x² + 64 = 4(41)
  • x² + 64 = 164
  • x² = 100
  • x = <u>10</u>

What represents the algebraic expression 3 p + 6 Over 7 p minus 9
MatroZZZ [7]
The answer is the sum of three times a number and six, divided by the difference of seven times a number and nine.

The phrase is(3p+6)/(7p-9)
Let’s describe each factor:
3p is three times a number
7p is seven times a number

3p+6 is the sum of three times a number and six
7p-9 is the difference of seven times the number and nine

The last two factors are divided, so
(3p+6)/(7p-9) is the sum of three times a number and six, divided by the difference of seven times the number and nine.

I hope this helped and have a nice day!

allsm [11]

Answer:

\boxed{\sf f(-3) = 9}

Given:

\sf f(x) =  {x}^{2}  - 2x

To Find:

Value of f(x) when x = -3

Step-by-step explanation:

\sf \implies f(x) =  {x}^{2}  - 2x \\  \\  \sf \implies f( - 3) =  {( - 3)}^{2}  - 2 ( - 3) \\  \\  \sf \:  \:  \:  \:  \:  \:   \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  = 3 - ( - 6) \\  \\  \sf \:  \:  \:  \:  \:  \:   \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  =3 + 6 \\  \\  \sf \:  \:  \:  \:  \:  \:   \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  =9
