Answer: 1. Proportional 2. Not Proportional
Step-by-step explanation: cross multiply.
1. 16*9=144
36*4=144
2. 8*80= 640
20*20=400
Answer:
Step-by-step explanation:
For problem #1 identify the coordinates of the point of intersection of the two lines. This point is (4, 2), and this is the solution to #1.
In problem #2 the lines never cross, and thus we conclude that there is no solution.
Answer:
3.5x=24.5
3.5x7=24.5
X=7
Step-by-step explanation:
3.5 times what equals 24.5
3.5x1=3.5
3.5x2=7
3.5x3=10.5
Keep doing this and increase the number you are multiplying 3.5 by until your answer is 24.5.
Answer:
<-3,4>
<0,-5>
Step-by-step explanation:
|-3w| = 15
3|-w| = 3|w| = 15
|w| = 
|w| = 5
- If vector w is represented by <1,-9>
Then |w| = 
.
Therefore this is not possible.
- If vector w is represented by <-3,4>
Then |w| = 
.
Therefore this is possible.
- If vector w is represented by <4,5>
Then |w| = 
.
Therefore this is not possible.
- If vector w is represented by <-5,-3>
Then |w| = 
.
Therefore this is not possible.
- If vector w is represented by <0,-5>
Then |w| = 
.
Therefore this is possible.
(NOTE : if z vector is represented by <x,y> then |z| = 
)
Answer:
m = 5
n = 12
Step-by-step explanation:
Opposite sides in a parallelogram are equal
so:
m+1 = 6
m = 6-1
m = 5
n is opposite to 12 so n = 12
