The absolute value of a number is its distance from zero on the number line. For example, -7 is 7 units away from zero, so its absolute value would be 7.

What is the slope of the line that passes through the points E(-1, 4) and F(2, 6)?

Phoenix [80]

The formula for finding the slope is:
(second y - first y)/(second x - first x)
so for this question you can say:
(6 - 4) / (2 - (-1)) = (2)/ (2+1) = 2/3 so the slope is 2/3 :)))
i hope this is helpful

Find the solutions of the given equation. 25x^2+64=289

AleksAgata [21]

Answer:

Step-by-step explanation:

Start by subtracting 64 from both sides:

$25x^2=225$

Factor this by taking roots. Divide both sides by 25 first:

$x^2=9$

We "undo" a square by taking the square roots of both sides. Taking the square root leaves the possibilities of both the positive and negative roots of 9. Therefore, the solutions to this are

$x=\sqrt{3},-\sqrt{3}$
