Find the coordinates of point X that lies along the directed line segment from Y(-8, 8) to T(-15, -13) and partitions the segmen

Nataly_w [17]

Answer:

C. (-13, -7)

Step-by-step explanation:

The location of a point O(x, y) that divides a line AB with location A $(x_1,y_1)$ and B $(x_2,y_2)$ in the ratio m:n is given by:

$x=\frac{m}{m+n} (x_2-x_1)+x_1\\\\y=\frac{m}{m+n} (y_2-y_1)+y_1$

Therefore the coordinates of point X That divides line segment from Y(-8, 8) to T(-15, -13) in the ratio 5:2 is:

$x=\frac{5}{5+2} (-15-(-8))+(-8)\\\\x=\frac{5}{7} (-15+8)-8=\frac{5}{7}(-7)-8=-5-8=-13 \\\\\\y=\frac{5}{5+2} (-13-8)+8\\\\y=\frac{5}{7} (-21)+8=5(-3)+8=-15+8=-7$

Therefore the coordinates of point X is at (-13, -7)

ANSWER

The correct answer is D.

$\sum_{n=1} ^{6} (n - 3) = ( - 2) + ( - 1) + (0) + (1) + (2) + (3) = 3$

EXPLANATION

The given expression is

$\sum_{n=1} ^{6} (n - 3)$

The symbol means summation.

So we need to substitute

$n=1,n=2,n=3,n=4,n=5, \:and\:n=6$

into the formula and add all to get,

$\sum_{n=1} ^{6} (n - 3) = (1 - 3) + (2 - 3) + (3- 3) + (4 - 3) + (5 - 3) + (6 - 3)$

We simplify to obtain,

$\sum_{n=1} ^{6} (n - 3) = ( - 2) + ( - 1) + (0) + (1) + (2) + (3) = 3$

The correct answer is D

Write the equation for 5x + 2y = 3 in slope-intercept form.

Vikki [24]

Answer:

B. y = -5/2x +3/2

Step-by-step explanation:

5x + 2y = 3

We want to get this in the form

y = mx +b where m is the slope and b is the y intercept

Subtract 5x from each side

5x -5x+ 2y =-5x+ 3

2y = -5x+3

Divide by 2

2y/2 = -5x/2 +3/2

y = -5/2 x +3/2
