Answer:
b
Step-by-step explanation:
if a is perp to b, and b is parallel to c, and c is parallel to d, then a is perp to d
Answer:
y = -3x-1 or 3x + y = -1
Step-by-step explanation:
6x + 3y - 11 = 0 can be written as y = -3x + (11/3)
In parallel lines the slope remains the same but the constant changes. To find the constant you place in the cordinates for x and y.
5 = -3(-2) + b
5 = 6 + b
5 - 6 = b
-1 = b
Now you replace (11/3) by the new b, -1
y = -3x - 1
Answer:
The actual distance is 11.7km
Step-by-step explanation:
2cm = 1km
1cm = 0.5km
23.4cm = ?
23.4 × 0.5 = 11.7km

Answer:
1. ratio - 1:4 (side to perimeter)
2. ratio - 4:1 (perimeter to side)
3. ratio - 1: 2 (radius to diameter)
Step-by-step explanation:
for 1. I just put 6/24 which simplies to 1/4. I tried the that with the rest and it equalled to 1/4
for 2. put 24/6 which is 4 (in fraction from 4 is 4/1)
for 3. 4/8 which equals to 1/2
I believe the answer to this is correct and i believe he did this by adding(i think)
