How do I find the y value for point I such that DI and EI form a 3:5 ratio.

3:5 ratio mean there are 8 "parts" (3 + 5 = 8)

The distance between the x-coordinates is |-3 - 5| = 8.
So each "part" is 8/8 = 1 unit long in the x-direction. 
You want I to be 3(1) = 3 units from D, so the x-coordinate of I is -3 + 3 = 0.

Same deal for y.
|2 - 5| = 3 is the distance between D and E
Each part is 3/8.
3(3/8) = 9/8
2 + 9/8 = 25/8

So the point I is (0, 25/8)

What is the equation of the line that passes through the point (5,6) and has a slope of 2 ?
Serhud [2]

Answer:

y = 2x - 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 2, thus

y = 2x + c ← is the partial equation

To find c substitute (5, 6) into the partial equation

6 = 10 + c ⇒ c = 6 - 10 = - 4

y = 2x - 4 ← equation of line

Y is directly proportional to x,and y=216 when x=2. Find y when x=7.

-------------------------------\\\\
\textit{we also know that }
\begin{cases}
y=216\\
x=2

\\\\\\
108=k\qquad therefore\qquad \boxed{y=108x}

\textit{when x = 7, what is \underline{y}?}\qquad y=108(7)

The perimeter of a rectangle is 70 inches. If its length is four times its width, find the dimensions. Write an equation and sol
katen-ka-za [31]

Answer: Length = 28cm

Width = 7cm

Step-by-step explanation:

Let the width be represented by x.

Since the length is four times its width. Therefore, the length would be:

= 4 × x = 4x

The perimeter of a rectangle is calculated as:

= 2(length + breadth)

Therefore, 2(4x + x) = 70

2(5x) = 70

10x = 70

x = 70/10

x = 7

Therefore, width = 7cm

Length = 4x = 4 × 7 = 28cm
