Find the smaller value of x that satisfies the equation x2 + 7x + 10 = 0
-5
-2
2
5
Correct answer is A
x2 + 7x + 10 = 0
x2 + 5x + 2x + 10 = 0
x(x + 5) + 2(x + 5) = 0
(x + 2)(x + 5) = 0
x + 2 = 0 or x + 5 = 0
x = -2 or x = -5
the smaller value x = -5x2 + 7x + 10 = 0
x2 + 5x + 2x + 10 = 0
x(x + 5) + 2(x + 5) = 0
(x + 2)(x + 5) = 0
x + 2 = 0 or x + 5 = 0
x = -2 or x = -5
the smaller value x = -5
Simplify 1\(\frac{3}{4} - (2 \frac{1}{3} + 4)\)
3\(\frac{5}{12}\)
2\(\frac{7}{12}\)
-4 \(\frac{7}{12}\)
-5 \(\frac{7}{12}\)
Correct answer is C
1\(\frac{3}{4} - (2 \frac{1}{3} + 4)\) = \(\frac{7}{4} - (\frac{7}{3} + \frac{4}{1})\); \(\frac{7 + 12}{3}\)
\(\frac{7}{4} - \frac{19}{3} = \frac{21 + 76}{12}\)
= \(\frac{-55}{12} = -4 \frac{7}{12}\)
What must be added to (2x - 3y) to get (x - 2y)?
5y - x
y - x
x - 5x
x - y
Correct answer is B
What must be added to 2x - 3y = Difference between x - 2y and 2x - 3y
x - 2y - 2y - (2x - 3y); x - 2y - 2x + 3y
= x - 2x + 3y - 2y
= y - x
