the arrowheads on the line means the line keeps on going and going like the Energizer Bunny and going to infinity, so the domain or extent horizontally will be

Complete the equation of the line through (-6, -5) and (-4, -4). Use exact numbers

77julia77 [94]

In general the equation through (a,b) and (c,d) is

$(y-b)(c-a)=(x-a)(d-b)$

Can you see that this is a line and that both (a,b) and (c,d) are on it?

Here we're given (a,b)=(-6,-5) and (c,d)=(-4,-4)

$(y- -5)(-4 - -6) = (x - -6)(-4 - 5)$

$2(y+5)=x+6$

$2y + 10 = x + 6$

$x - 2y = 4$

$y = \frac 1 2 x - 2$

Either of the last two are fine answers.

Suppose that for a certain experiment p(b)equals=0.5 and p(avertical line upper bb)equals=0.2. find p(aintersect∩b).

raketka [301]

P(a | b) = p(a ∩ b)/p(b) . . . . . a definition worth remembering
0.2 = p(a ∩ b)/0.5 . . . . . . . . fill in the given values
0.2*0.5 = 0.1 = p(a ∩ b)

p(a ∩ b) = 0.1

Rodney is making three pizzas. The recipe says that, for one pizza, he needs 2 cups of flour, 2 teaspoons of instant active dry

Mamont248 [21]

Answer:

14 cups of flour.

Step-by-step explanation:

Rodney is making three pizzas.

The recipe says that for one pizza he needs flour = 2 cups

Rodney buy a bag of flour containing = 20 cups flour

Rodney needs flour for three pizzas = 3 × 2 = 6 cups

He will have left over flour after making the pizzas = 20 - 6
