Answer:
1 (-4,5), (-2,1) (2,2) (5,5)
2 (0,1) (-4,3) (-4,1)
Step-by-step explanation:
Answer:
x=-2, y=-3
Step-by-step explanation:
we can rearrange the questions to make it easier
y=3x+3
2y=-3x-12
if you add the two equations, you get
3y=0x-9
so y=-9/3 = -3
plug y into one of the equations
-3=3x+3
-6=3x
x=-2
and then check your work by plugging into the other equation:
2*-3=-3(-2)-12
-6=6-12
-6=-6
Answer:
the 2nd and 4th expressions are the appropriate ones.
Step-by-step explanation:
both result in '0' which means that kiana is on the ground floor of the building at the end.
60/15=4 meaning 25% of the dogs are purebreed
Ok so remember
x^n means x times itself n times
example
x^2=x times x
x^4=x times x times x times x
so
a^3
a=7
a^3=a times itself 3 times therefor
a^3=a times a times a
subsitute 7 for a
7^3=7 times 7 times 7
7^3=343
