49. The line containing (1, -3) and (3, y) is parallel to the line containing (5, -6) and (9, y).
How do I find y?

Answers

Answer 1

Answer:

y = 0

Step-by-step explanation:

Parallel lines have equal slopes

Calculate the slopes of both lines and equate them

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (1, - 3 ) and (x₂, y₂ ) = (3, y )

m = [tex]\frac{y-(-3)}{3-1}[/tex] = [tex]\frac{y+3}{2}[/tex]

Repeat with (x₁, y₁ ) = (5, - 6 ) and (x₂, y₂ ) = (9, y )

m = [tex]\frac{y-(-6)}{9-5}[/tex] = [tex]\frac{y+6}{4}[/tex]

Equating the 2 expressions

[tex]\frac{y+3}{2}[/tex] = [tex]\frac{y+6}{4}[/tex] ( cross- multiply )

4(y + 3) = 2(y + 6) ← distribute parenthesis on both sides

4y + 12 = 2y + 12 ( subtract 2y from both sides )

2y + 12 = 12 ( subtract 12 from both sides )

2y = 0 , then

y = 0

What the equation in point-slope form, matchs the graphed line shown

Answers

Given points (0, 1) and (-7, 5):

Let (x1, y1) = (0, 1)
(x2, y2) = (-7, 5)

First, solve for the slope of the line using the formula:

m = (y2 - y1)/(x2 - x1)
m = (5 - 1) / (-7 - 0)
m = 4/-7 = -4/7

Now that we have our slope, m = -4/7, we can plug this in, along with one of the given points, (0, 1), into the point-slope form:

y - y1 = m(x - x1)

y - 1 = -4/7(x - 0) ← This is the point-slope form

If 2k - 3 = 9 (k+7)-3 then k is ????

Answers

Answer:

k= -9

Step-by-step explanation:

2k-3=9k+63-3     [expand the 9(k+7) first]

2k-9k=63-3+3     [put the like terms together]

-7k=63                 [do the simple math]

k= 63 ÷ by -7

k=-9  

Answer:

K = -9

Step-by-step explanation:

2k-3 = 9(k+7)-3

2k-3 = 9k+63-3

2k-3 = 9k+60

2k-9k = 60+3

-7k = 63

-k = 9

k = -9

Answer:

hat = 5pumpkin = 2ghost = 7cauldron = 10

Step-by-step explanation:

Using h, p, g, c to represent the values of the hat, pumpkin, ghost, and cauldron, respectively, we can write 5 equations:

gh +h = 40cp +p = 22g +2c = 27ph +g = 172g +h = 19

Solving the last equation for h, and substituting into the first equation gives ...

  h = 19 -2g

  g(19 -2g) +(19 -2g) = 40

  2g^2 -17g +21 = 0 . . . . . . . . write in standard form

  (2g -3)(g -7) = 0 . . . . . . . factored form

The values of g that make the factors zero are g = 3/2 and g = 7. If we assume the solution is restricted to integer values, then g = 7, and ...

  h = 19 -2·7 = 5

From equation 4, ...

  5p +7 = 17   ⇒   p = 2

From equation 3, ...

  7 +2c = 27   ⇒   c = 10

The values of the symbols are ...

hat = 5pumpkin = 2ghost = 7cauldron = 10
