Agraph displays point a (5, 3, 4) and point b (-4, 2, 6). calculate the approximate distance each point is from the origin.
round to the nearest tenth.
which point is farther from the origin, and by how much?
point b is 0.4 units farther.
point a is 0.4 units farther.
point a is 2.6 units farther.
point b is 2.6 units farther.

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
