Assuming none of the factors is zero, if an odd number of the factors of a multiplication problem have negative signs, then the product will be negative. Otherwise, the product is positive.
Assuming the dividend of a division problem is non-zero, the quotient wil be negative if the signs of the dividend and divisor are differnt. Otherwise the quotient is positive.
In short, if a multiplication or division problem involves an odd number of minus signs, the result will be negative. Otherwise, the result is positive.
Answer:
Step-by-step explanation:
Since it is an isosceles triangle, 34 = x-5.
x=39 and 4y =180-(34+34)
4y=112
y=28
Answer:
next three terms: 12, 6, 0
Step-by-step explanation:
subtract 6 from 18, which is 12, then subtract another 6 from 12, then do it again for the last term
5(2x+5y=16)+2(-5x-2y=2)
10x-10x+25y-4y=80+4
21y=84
y=4, making 2x+5y=16 become:
2x+5(4)=16
2x+20=16
2x=-4
x=-2
So the solution to the system of equations is the point (-2, 4)
