Assuming you meant y=3/4x-3, the answer is y=-4/3x-3
Answer: B is 11 feet tall
A=x+1 since A is one more than B
C=x+1/2 since C is one half more than B
B=x since B is just B
A+B+C=34.5
x+1+x+x+1/2=34.5
3x+1.5=34.5
3x=33
x=11
B is 11 feet tall
Answer:
14
Step-by-step explanation:
We solve this by using 2 to open the bracket
(3+4)2 is the same as 2(3+4)
2(3)+2(4)
=6+8
=14
OR
(3+4)2 is the same as 2(3+4)
So we can solve the one inside the bracket first
=2(7)=14

Answer:
option-C
Step-by-step explanation:
We are given row-echelon form
So, we can write equation from matrix as


Let's assume

now, we can find x and y




so, we get solutions as



where t can be any real numbers
