What is the distance between points P(0, 4) and Q(3, 0)?

1 answer:

5 0

$PQ= \sqrt{(x_p-x_q)^2+(y_p-y_q)^2}= \sqrt{(0-3)^2+(4-0)^2} = \\ \\ = \sqrt{(-3)^2+4^2}= \sqrt{9+16}= \sqrt{25}=5$

Answer: 5

What is the answer????

Liula [17]

Answer:

$(5, 6)$

Step-by-step explanation:

Step 1: Solve for x in the first equation

$x - y + y = -1 + y$

$x = y - 1$

Step 2: Plug in x into the second equation

$(y - 1) - 3y = -13$

$y - 1 - 3y + 1 = -13 + 1$

$-2y / -2 = -12 / -2$

$y = 6$

Step 3: Plug in y into the first equation

$x - (6) + 6 = -1 + 6$

$x = 5$

Answer: $(5, 6)$

Answer: The answer in simplest form is $-6(1/4)$

Step-by-step explanation:

In Wyatt's method I observed the mixed fraction was converted to simple fraction in the second step.

Therefore Wyatt's solution will be:

$2/5 * -15(5/8) = 2/5 * -125/8 = -25/4$

Distributive property was used in Abigail's method.

The solution would be:

$2/5 * -15(5/8) = 2/5(-15 -5/8) = 2/5(-15) + 2/5(-5/8) = -6(-1/4)$
