What we know:
a, b and c are not zero
abc=c
What we need to find:
a
abc=c
abc/bc=c/bc additive inverse
a=1/b simplified
Answer:
1) x= -2
2) x= 3
3) x=7
4) x>5
5) x=-14
Step-by-step explanation:
1) −3x − 3 −7x = 17
−10x−3=17
−10x=17+3
−10x=20
x= -20/10
x=-2
2) 10x − 6 = 24
10x=24+6
10x=30
x= 30/10
x= 3
3) −4−5x=−39
−5x=−39+4
−5x=−35
x=-35/-5
x= 7
4) 3x - 5 > 10
3x>10+5
3x>15
x>15/3
x>5
5) -5 + x + 16 = -3
x+11=−3
x=−3−11
x=-14
The value is -6
(-1,-6)
all you have to do it plug in -1 for x
f(-1)= -2(-1+4
f(-1)=-2(3)
f(-1)=-6
