Answer: the following system of equations has 2 solutions
x1=4
X2=-2
Step-by-step explanation:
5*x+4=x²+3*x-4
x²-2*x-8=0
x12=(2+/-√4+4*1*8)/2
x12=(2+/-√36)/2
x1=(2+6)/2=4
x2=(2-6)/2=-2
4b^-6
When u have a negative exponent, u simply take the reciprocal. So the answer is
4/b^6
Answer:
3 shirts and 6 skirts
Step-by-step explanation:
lets call number of shirts x and number of skirts y
so x+y=9
17x+22y=168
multiplying the first equation by 17 we get
17x+17y=153
17x+22y=168
subtracting we get
5x= 15
x=3
and we know x+y=9 so y=6
so 3 shirts and 6 skirts
