You would put these in a fraction then cross multiply so 15/1800 and 3/x then you get 5400 equals 15x then divide by 15 on both sides to get x equals 360

BRAINLIESTTT ASAP! PLEASE HELP ME :)
Scrat [10]

x-intercepts: (-3,0), (1,0)

work:

0 = x^2 + 2x - 3

quadratic equation: x = -2 +√(2^(2) - 4 × 1(-3)) / (2 × 1) = 1

quadratic equation: x = -2 -√(2^(2) - 4 × 1(-3)) / (2 × 1) = -3

(x,y) --) (-3,0), (1,0)

y-intercept: (0,-3)

work:

y = (0)^2 + 2(0) - 3

y = -3

(x,y) --) (0,-3)

vertex: (-1,-4)

work:

xv = -( b / (2a) )

a = 1, b = 2, c = -3

xv = -( 2 / (2×1) )

xv = -1

yv = (-1)^2 + 2(-1) - 3

yv = -4

(x,y) --) (-1,-4)

axis of symmetry: -1

work:

a = 1 in the x^(2) + 2ax + a^(2)

x^(2) + 2x + 1^(2) = (x + 1)^(2)

(x + 1)^(2) - 3 - 1^(2)

y = (x + 1)^(2) - 4

y + 4 = (x - 1)^(2)

put in standard form --) 4 × 1/4( y -( -4 ) ) = ( x -( -1) )^(2)

(h,k) = (-1,-4); p = 1/4

in parabola form expression: 4p( y - k ) = ( x - h )^(2) and is symmetric around the y-axis at -1.

Julie has a bag of p blue marbles and q red marbles in the ratio 2:3. She adds r blue marbles. The ratio of blue marbles to red
ruslelena [56]
I'm not sure how to answer the question... BUT, I know that the side that says 2 is for the blue marbles and 1 is for the red marbles, meaning that every 2 blue marbles she has equal 1 red marble. 
Sorry I didn't have the answer, hope this helps :/

What are the coordinates of the point on the directed line segment from (-6,9) to
brilliants [131]

Answer:

Step-by-step explanation:

difference of x-coordinates = 4-(-6) = 10

difference of y-coordinates = -1-9 = -10

partition the differences into a ratio of 1:4

10 × 1/(1+4) = 2

-10 × 1/(1+4) = -2

(-6+2,9-2) = (-4,7)
