4)
Area=(base x height) / 2
area=24 in²
therefore:
(b*3b)/2=24 in²
3b²/2=24 in²
b²=(24*2)/3 in²
b²=16 in²
b=√(16 in²)= 4 in
answer: 4 in
5)
if x=9
x²+z=103
(9)²+z=103
81+z=103
z=103-81=22
if x=-9
(-9)²+z=103
81+z=103
z=103-81=22
Answer: 23
1)
n²-49=0
n²=49
n=⁺₋√49=⁺₋7
Answer: ⁺₋7
2)
x²+64=0
x²=-64
x²=⁺₋√-64 These numbers are not real.
Answer:no solution
3)
area=slide²
slide=+√area
slide=+√(144x²)=12x
answer: 12 x
1. The equations are Consistent and Independent because they intersect at only one point.
2. The equations are Consistent and dependent because there are infinite solutions.
3. The equations are Inconsistent because they never intersect.
4. The equations are Consistent and Independent because they intersect at only one point.
I hope this helps :)
