If you meant to write y=23x-4 then none of the lines are perpendicular.
I suspect you intended y=2/3x-4, then line D, y=-3/2x-4 is perpendicular.
For any line y=mx+b, you have to "invert" m to get a perpendicular line. Inverting in this case means: flip numerator and denominator and add a minus sign.
So 2/3 becomes -3/2, hence answer D.
The 'inverted' m is called the opposite reciprocal. That's your word of the day.
Answer:
<em>The length of the actual ship is 125 meters.</em>
Step-by-step explanation:
<u>Scaling</u>
Objects can be represented in a reduced or augmented size by using scaling which is basically multiplying or dividing by a constant factor. We use scaling for example, when representing geographic locations on a map.
A model ship is built to a scale of 1 cm: 5 m. This means that each centimeter of the model represents an actual length of 5 m.
The length of the model is 25 cm, thus the real ship has a length of 25*5 = 125 m.
The length of the actual ship is 125 meters.
Answer:
6 times
Step-by-step explanation:
Turn that fraction into a decimal. 3/4=0.75
Divide!
4.5/0.75=6
Answer:
E(3.75,-2.5)
G(-0.75,-3)
Step-by-step explanation:
Point E is the midpoint of the segment AB, then it has coordinates
Point F is the midpoint of the segment EB, then it has coordinates
Let S be the midpoint of segment CB, then it has coordinates
Point G is the midpoint of segment CS, then its coordinates are
