How long is the segment from(-5,2)to(-5,-8)

Mathematics
1 answer:
dusya [7]3 years ago
6 0

Answer:

10

Step-by-step explanation:

To calculate the distance d use the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (- 5, 2) and (x₂, y₂ ) = (- 5, - 8)

d = \sqrt{(-5+5)^2+(-8-2)^2}

  = \sqrt{0^2+(-10)^2}

  = \sqrt{0+100} = \sqrt{100} = 10

What values of a and b would make the equation shown have infinitely many solutions? 3x=ax+b
Wittaler [7]
Infinitely many solutions means that you have the same thing on both sides of the equation no matter what value of x you plug in, right?

We just need both sides to be 3x then, correct?

If a were equal to 3 and b were equal to 0, we'd have

3x = (3)x + 0

Which is essentially 3x = 3x

So that means a = 3 and b = 0 must work!
Let's say x = 5

3(5) = 3(5) + 0

15 = 15 + 0

15 = 15

That means that a = 3 and b = 0 is your final answer :)

Please help me with this problem..
charle [14.2K]

Answer:

y = 6

Step-by-step explanation:

Given that y varies directly with x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = 3 when x = 9, then

k = \frac{y}{x} = \frac{3}{9} = \frac{1}{3}, thus

y = \frac{1}{3} x ← equation of variation

When x = 18, then

y = \frac{1}{3} × 18 = \frac{18}{3} = 6
