What is the y coordinate of the point that divides the

Mathematics
1 answer:
svet-max [94.6K]3 years ago
6 0

Answer:

the y coordinate is 5

Step-by-step explanation:

In the figure attached, the  directed line segment is shown.

J is located at (-3, 1) and K is located at (-8, 11)

run: x2 -x1 = -8 - (-3) = -5

rise: y2 - y1 = 11 - 1 = 10

Taking J as reference, the coordinate of the point that divides the  directed line segment from J to k into a ratio of 2:3 is:

c = 2/(2+3) = 0.4

(x1 + c*run, y1 + c*rise)

(-3 + 0.4*-5, 1+0.4*10)

(-5, 5)

3. Which expression is equivalent to 1+2(x-1)
padilas [110]

Answer:

<em>2x - 1</em>

Step-by-step explanation:

<u>Equivalent Algebraic Expressions </u>

One algebraic expression can be written in several ways by applying known rules and theorems that modify expressions without changing its final value.

The expression:

1 + 2(x - 1)

Can be modified by applying the following operations:

Multiplying the constant by the contents in parentheses:

1 + 2x - 2

Collecting like terms:

-1 + 2x

Or, equivalently:

2x - 1

Give the slope between the points<br> (2,5) (14,-4)
andrezito [222]

Answer:

-\frac{3}{4}

Step-by-step explanation:

Slope

(2, 5) and (14, -4)

_______________

When we solve for slope within two points, we have to follow the formula of slope.

\frac{y^2-y^1}{x^2-x^1}

X and Y - The first and second number in both points

1 and 2 - The first or second number within one point

Substitute :

\frac{-4-5}{14-2}

\frac{-9}{12}

Simplify :

-\frac{3}{4}
