Answer:

y-coordinate = 0

Step-by-step explanation:

Consider the below diagram attached with this question.

Section formula:

If a point divides a line segment in m:n whose end points are (x_1,y_1) and (x_2,y_2), then the coordinates of that point are

(\frac{mx_2+nx_1}{m+n},\frac{my_2+ny_1}{m+n})

From the below graph it is clear that the coordinates of end points are J(1,-10) and K(7,2). A point divides the line JK is 5:1.

Using section formula, the coordinates of that point are

(\frac{(5)(7)+(1)(1)}{5+1},\frac{(5)(2)+(1)(-10)}{5+1})

(\frac{35+1}{6},\frac{10-10}{6})

(\frac{36}{6},\frac{0}{6})

(6,0)

Therefore, the y-coordinate of the point that divides the directed line segment from J to k into a ratio of 5:1 is 0.

Solve negative 5 over 2, the whole multiplied by x minus 5 equals negative 55.
astraxan [27]

Answer:

-24

Step-by-step explanation:

-  \frac{5}{2} x \:  - 5 = 55

Multiply through by the denominator (that is, 2)

= 2 \times ( -  \frac{5}{2} x) \:  - 5(2) = 55(2)

=  - 5x - 10 = 110

Collect like terms

- 5x \:  = 110 +10

- 5x = 120

Divide through by - 5x

\frac{ - 5x}{ - 5}  =  \frac{120}{ - 5}

x =  - 24

Will mark you as brainliest. If your good with polynomials.
kobusy [5.1K]
To solve/simplify this all you have to do is group like terms (the x^2's with each other, the x's with each other, and the normal numbers, -8)

14x^2-8+5x-6x^2+2x

group the x^2 (add 14x^2 to -6x^2)

8x^2-8+5x+2x

group the x's together (add 5x and 2x together)

8x^2+7x-8

Your answer will be d) 8x^2+7x-8
