<span>the equation -2x² + 5x -3=0, we notice that the sum of the coefficient equals 0, -2+5-3=0, if such a case happens, the solution of the previous equation will be, x=1 (always) and x= c/a, a=-2, and c=-3, so x=-3/-2, finally, the answer is: the 2 in the denominator should be -2</span>
<span>if a trip from earth to mars, is 97/186=.52150
and
a trip from earth to venus is 0.2774(now we have to times it by 2 since its a roundtrip),
we get .5548
we can clearly see that .5548>.52150
So roundtrip venus</span>
Answer:
Y-1 = 10(X-7)
Step-by-step explanation:
Y -Y1 = M(X - X1)
Y1= 1
X1= 7
M= SLOPE
SLOPE= -9-1 DIVIDED BY 6-7.
-10 DIVIDED BY -1 EQUALS 10
Value of x is 
and y is 
Solution set is (, )
Step-by-step explanation:
We need to solve the system of equations given.
Solving
Let:
Multiply eq(1) by 3 and eq(2) by 2 and add both
Putting value of y in equation 1
So, value of x is and y is
Solution set is (, )

Answer:
3
Step-by-step explanation:
Evaluate the calculation from left to right, that is
3 - 24 - 8 + 32
= - 21 - 8 + 32
= - 29 + 32
= 3
