This answer key solves every problem in the Unit 4 Lesson 9 homework: evaluating and graphing an absolute value function, disproving equivalence, drawing step functions, and reading postage endpoints correctly.
The six Independent Practice answers use one test throughout: divide the dependent quantity by the independent quantity and verify that the constant ratio agrees with the equation, table, or graph.
The linear table is the one whose y-values increase by one-half whenever x increases by 1. That constant first difference gives slope 1/2 and the equation y = (1/2)x.
Solve the complete set of 24 Lesson 3.4 multi-step equations using distribution, like-term collection, exact fractions, and substitution checks.
Translate, reflect, and rotate coordinate pairs, compare transformations with algebra functions, and compose rules in the correct order.
Work through the GSE Geometry Unit 1 Review #1 with angle equations, transversal relationships, and exact coordinate rules for eight transformations.
Solve the GSE Geometry Unit 4 review with circle-angle theorems, intercepted arcs, cyclic quadrilaterals, arc length, and sector area.
With two possible bases at each codon position, a codon of length n has 2^n possible sequences. Four positions provide only 16 codes, while five provide 32, so five bases is the minimum needed to encode 17 amino acids.
Bacteria divide with an FtsZ-guided constriction and septum, animal cells use an actin-myosin cleavage furrow, and plant cells build a microtubule-guided cell plate because their rigid wall prevents furrow constriction.
