Answer:
4 : 12 : 15
Step-by-step explanation:
S : J = 1 : 3
J : P= 4 : 5
Using John's ratio to find a common ratio for all
S : J
(1 : 3)4 = 4 : 12
J : P
(4 : 5)3 = 12 : 15
Therefore our ratio is
S : J : P
4 : 12 : 15
Answer:
y= -3/4x-1
Step-by-step explanation:
The points are (8,-7) and (0,-1)
The slope is the change in Y over the change in X, so you have -3/4 as your slope.
Then, you have y=-3/4x+b
You substitute either (8,-7) or (0,-1) for X and Y in the equation, and solve it, giving you -1 for B
So you need to know 32 centimeters in what?
1) -12 meters
2) 28 meters
3) 40 meters apart
The equation of a line is .
Solution:
Given slope, m = and passes through the point (–3, –1).
Equation of a line passes through one point and slope formula:
Here, and
Substitute these in the given formula, we get
⇒
⇒
Cross multiply the fraction.
⇒
⇒
Subtract 3 on both sides of the equation.
⇒
⇒
Divide by 3 on both sides of the equation.
⇒
Hence, the equation of a line is .
