I. Select the option that gives the correct answer. Check the box. 1) What should h be so that the expression h? - 2h has a value of 3 ?
Th = 1 Oh=-1 h = 2
h = -2
2) What should b be so that the expression (3b + 10) has a value of 1?
b=-3 0 b = 2 b= -2 b= 3
3) What should y be so that the expression 1 - yl has a value of 25?
y=-6 y=2 y=-4 y = 5
4) What should m and n be so that the expression 3m² + nm has a value of 0 ?
m=-1, n = 3 m = 2, n = -1 m = 3, n = 2 m = -3,n=0
5) What should a and b be so that the expression ala-2b) -b has a value of -11?
O a=-4,6 = 6 a = 5, b = 8 O a = 7, b = 4 O a=6, b = -5
6) What should x and y be so that the expression -(x - y) + 2(x + y) has a value of 4?
O x = 2. y=-2 x=-2, y = 2 x=3, y = -3 0 x = -3. y = 3
