Answer:
y=-(4x/3) -1
Step-by-step explanation:
Slope=m= -4/3
y intercept = c = -1
now using equation;
y= mx+c
y= (-4/3)x+(-1)
y=-(4x/3) -1
3n-5=-8(6+5n) First distribute -8 to 6 and 5n
3n-5= -48-40n Move variables using opposite operations ,n-terms should be on the left
43n-5=-48
43n=-43
43n/43=-43/43 n=-1
-(1+7x)-6(-7-x)=36 There is an invisible -1 in front of the first parenthesis. We know it's here because of the negative sign before the first parenthesis. Distribute -1 to (1+7x) and -6 to (-7-x).
-1-7x+42+x+=36 Now combine x-terms with x-terms and regular numbers with regular numbers. This is called combining like terms.
42-6x=36 Move 42 by substracting 42 from 42 and from 36
-6x=-6 Divide -6x by -6 and -6 by -6
x=1
-3(4x+3)+4(6x+1)=43 Distribute -3 to (4x+3) and -4 to (6x+1)
-12x-9+24x+4=43 Combine like terms(explained above)
24x-5=43 Add 5 to -5 and to 43
24x=48 Divide 24x And 48 by 24
x=2

a
Step-by-step explanation:
1/3 is one third and times by 30
Interval notation uses an ordered pair inside brackets. The ordered pair is ...
... lower end of the interval, upper end of the interval
The brackets are square if the endpoint is included (solid dot, or "≤"), and they are curved (parentheses) if the endpoint is not included (open dot, or "<"). The brackets don't have to match.
Here, your interval is -4 ≤ x ≤ -1, so we use square brackets around the end values -4 and -1.
... [-4, -1]
