An archaeologist is comparing the location of a jeweled box she just found to the location of a brick wall. The wall can be represented by the equation y= -5/3x + 13. The box is located at the point (10,9). Write an equation representing a line that is perpendicular to the wall and that passes through the location of the box.

last one.

step-by-step explanation:

last one.

generally speaking, the others follow some sort of pattern that correlates to either linear (looks like a straight line) or sinusoidal (looks like an s).

the last one is just a random cloud of points that doesn't correlate to any particular known order.

answer is because 4×10=40

and 98×4= is 392

40,392

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
