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
Answer:
1,075
Step-by-step explanation:
4,870-2575=2295
2295-1220=1075
-2(6-8)
-2(-2)= 4
-2(6 - 8) using distributive property
(-2 x 6) (-2 x - 8)
-12 + 16 = 4
so if she did the above step, she should get 4
the error might be that she failed to distribute to both 6 & -8 (but idk since technically idk what she did)
hope this helps
