Answer:

M = (3, 3.25)

Step-by-step explanation:

First, using the internal selection formula

Given

m:n = 3:5

(x1,y1) =(0,1)

(x2,y2) =(8,7)

M={[(mx2+nx1)/(m+n)],[(my2+ny1)/(m+n)]}

M = (3, 3.25)

2.

M is the point on XY that is 3/8 of the way from X to Y.

x-coordinate of M = 0 + (3/8)(8) = 0 + 3 = 3

y-coordinate of M = 1 + (3/8)(6) = 1 + 2.25 = 3.25

So, M = (3, 3.25)

or (3, 3 1/4)

10(x+3)-(-9x-4)= x-5 +3
kakasveta [241]

Answer:

Step-by-step explanation:

Simplifying

10(x + 3) + -1(-9x + -4) = x + -5 + 3

Reorder the terms:

10(3 + x) + -1(-9x + -4) = x + -5 + 3

(3 * 10 + x * 10) + -1(-9x + -4) = x + -5 + 3

(30 + 10x) + -1(-9x + -4) = x + -5 + 3

Reorder the terms:

30 + 10x + -1(-4 + -9x) = x + -5 + 3

30 + 10x + (-4 * -1 + -9x * -1) = x + -5 + 3

30 + 10x + (4 + 9x) = x + -5 + 3

Reorder the terms:

30 + 4 + 10x + 9x = x + -5 + 3

Combine like terms: 30 + 4 = 34

34 + 10x + 9x = x + -5 + 3

Combine like terms: 10x + 9x = 19x

34 + 19x = x + -5 + 3

Reorder the terms:

34 + 19x = -5 + 3 + x

Combine like terms: -5 + 3 = -2

34 + 19x = -2 + x

Solving

34 + 19x = -2 + x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-1x' to each side of the equation.

34 + 19x + -1x = -2 + x + -1x

Combine like terms: 19x + -1x = 18x

34 + 18x = -2 + x + -1x

Combine like terms: x + -1x = 0

34 + 18x = -2 + 0

34 + 18x = -2

Add '-34' to each side of the equation.

34 + -34 + 18x = -2 + -34

Combine like terms: 34 + -34 = 0

0 + 18x = -2 + -34

18x = -2 + -34

Combine like terms: -2 + -34 = -36

18x = -36

Divide each side by '18'.

x = -2

Simplifying

x = -2

Write an equation of the line that passes through the given point P and
dexar [7]

Answer <u>(assuming it can be in point-slope form)</u>:

y-4 = 3(x+2)  

Step-by-step explanation:

Use the point-slope formula y-y_1 = m (x-x_1), to write the equation of the line in point-slope form. Substitute x and y values for m, x_1, and y_1 in the formula.

Since m represents the slope, substitute 3 for it. Since x_1 and y_1 represent the x and y values of a point the line intersects, take the x and y values of point P and substitute them into the equation as well. Substitute -2 for x_1 and 4 for y_1. This gives the following answer:

y-4 = 3(x+2)
