Algebra 1 Semester 1 Final Exam
1) (..., -3, -2, -1, 0, 1, 2, 3,)
2) (a× b) ×c=a× (b×c) is an associative property of multiplication
3) 4x+20-3x-6=14
4) x(5−3) y(2−6) z
= x2 z
y4
5) (x2y3)2*(x3y) 3= ( x2.2 y3.2) × (x3.3 y3
)
=x4y6*x9y3=x13y9
1.256097 rounded off to the nearest thousandth is 1.256
7) 36/48 into percentage =36/48*100=75%
8) First step in evaluating {6 [2 ( 6−4 ) ] } ÷ 4 is 6-4
9) 1 oz=28.3495 g
22 oz=22*28.3495=623.69 g=624 g
10) (x-4) (x+7) =0
x-4=0; x=4 or x+7=0; x=-7
11) 3(x-2) =3x(x-2); (x-2) cancels out on both sides hence we are left with 3=3x. dividing
through by 3; x=1
12) 5x+y=-23; when x is 0, y=-23 and when y=0, x=-23/5

13) Cannot be determined
14) Graph D
15) Find (f⁰g) (4) when f(x) =4x+5 and g(x) =4x2-5x-3
Evaluate (f (g)) by substituting in the value of g into f
4(4x2-5x-3) +5=16x2-20x-12+5
=16x2-20x-7
16) A
17) B
18) Graph C
19) Graph of g(x) =|x|+3 is C
20) Graph A
