Answer: the summation from n equals one to 5 of quantity negative 1 minus 4 times n
Answer:
(-4,-1)
Step-by-step explanation:
-3x+10y=2
-3x+3y=9
-3x=2-10y
-3x=9-3y
2-10y=9-3y
2-9=10y-3y
7y=-7
y=-1
-3x+3(-1)=9
-3x-3=9
-3x=12
x=-4
A correct possibility could be $37.50 because 37.50 x 2 + 4 = 79
Answer:
1) -32+12x 2) 2(3x-4)
Step-by-step explanation:
I hope this is right!
It is just asking to find the sum of interior angles
So follow this rule 180(n-2)
180(5-2)
180(3)= 540
So in another words: a+b+c+d+e=540
