Answer:

2. m = 1

3. y - (-1) = 5 (x - 4)

4. y = 5x - 21

Step-by-step explanation:

<u>Work for #2</u>

m (slope) = \frac{y2 - y1}{x2 - x1} \fracyx}

m = \frac{-1 - 2}{-2 -1}

m = \frac{-3}{-3}

m = 1

<u>Work for #3</u>

y = -1/5x + 3 and through (4, -1)

The slope of a perperndicular line is the negative reciprocal. So, it is 5.

Plug this number into point-slope form. Use the points you were given (4,-1) in the equation as well.

y - y1 = m (x - x1)

y - (-1) = 5 (x - 4)

y + 1 = 5x - 20 (Only if you are supposed to simplify it)

<u>Work for #4</u>

Finish solving the equation

y - (-1) = 5 (x - 4)

y + 1 = 5x - 20

y = 5x - 20 - 1

y = 5x - 21

Which answer is a solution of the equation?
Nuetrik [128]

2x + y = 5

Put the coordinates of the points to the equation and check it:

A. 5 - not make sense

B. (1, 2) - x = 1, y = 2

2(1) + 2 = 2 + 2 = 4 ≠ 5  NOT

C. (2, -1) - x = 2, y = -1

2(2) + (-1) = 4 - 1 = 2 ≠ 5    NOT

D. (3, -1) - x = 3, y = -1

2(3) + (-1) = 6 - 1 = 5    YES

<h3>Answer: D. (3, -1).</h3>

How many solutions does 3 - 2x = 5 - x + 3 + 4x have?
vitfil [10]

Well let's see.

3-2x=5-x+3+4x \\3-2x=8+3x \\-5x=5 \\x=-1 \\

The equation has exactly one solution.

Hope this helps.

Sandra saves 7% of her salary for retirement. This year her salary was $2,000 more than her salary than in the previous year, an
Effectus [21]

9514 1404 393

Answer:

  • 2,000
  • $45,000

Step-by-step explanation:

Where x represents the previous year's salary, its amount this year is said to be ...

  x + 2000

The equation is trying to reflect the fact that 7% of that is $3,290. The missing number is 2000:

  0.07(x +2000) = 3290

__

Solving for x, we find ...

  x = (3290/0.07) -2000 = 45000

Sandra's salary the previous year was $45,000.
