Answer: Rewrite equations:
5x+y=−13;6x+6y=−6
Step: Solve5x+y=−13for y:
5x+y=−13
5x+y+−5x=−13+−5x(Add -5x to both sides)
y=−5x−13
Step: Substitute−5x−13foryin6x+6y=−6:
6x+6y=−6
6x+6(−5x−13)=−6
−24x−78=−6(Simplify both sides of the equation)
−24x−78+78=−6+78(Add 78 to both sides)
−24x=72
−24x
−24
=
72
−24
(Divide both sides by -24)
x=−3
Step: Substitute−3forxiny=−5x−13:
y=−5x−13
y=(−5)(−3)−13
y=2(Simplify both sides of the equation)
Answer:
x=−3 and y=2

Answer:
Find the domain by finding where the expression is defined. The range is the set of values that correspond with the domain.
Domain: (−∞,0)∪(0,∞),{x|x≠0}(-∞,0)∪(0,∞),{x|x≠0}
Range: ,{x|}
Answer:
0.875 as a decimal
875/1000 or 7/8 as a fraction
explanation:
7/8 = 0.875
875/1000 = 0.875
hope this helps :)
