Answer:
I think the answer is 5 ( if wrong then do a low rating)
Step-by-step explanation:
The way I found the answer was by using PEDMAS so first I handled [(4 - (-5)) x (-7)] which is the same as 4 + -5 which equals -1 and when multiplied by -7 equals positive 7 because whenever you multiply 2 negatives you get a positive.
Next I solved 6 / (-3) which is -2 since whenever a positive is divided by a negative the quotient is negative. Now the equation is:
-2 + 7 and when solved is -2 + 7 = 5
Answer:
-1
Step-by-step explanation:
1+4.5x+4.9x=-8.4
4.5x+4.9x=-8.4-1
9.4x=-9.4
x=-9.4/9.4
x=-1

Answer:
11/5
Step-by-step explanation:
FirLet a and b be the roots of 11x^2-4x-2=0
Now
Dividing the quadratic equation by 11 we have

Now the sum of the roots is the minus of the coefficient of x and the product of the roots is the constant. Therefore

and we have
