7. two equations are given below: a – 3b = 4 a = b – 2 what is the solution to the set of equations in the form (a, b)? (5 points) (–2, –2) (–3, –1) (–9, –7) (–5, –3) 8. a student is trying to solve the set of two equations given below: equation a: x + z = 6 equation b: 2x + 4z = 1 which of the following is a possible step used in eliminating the z-term? (5 points) multiply equation b by 4. multiply equation a by 2. multiply equation a by –4. multiply equation b by 2. 9. the work of a student to solve a set of equations is shown: equation a: y = 4 – 2z equation b: 4y = 2 – 4z step 1: –4(y) = –4(4 – 2z) [equation a is multiplied by –4.] 4y = 2 – 4z [equation b] step 2: –4y = 4 – 2z [equation a in step 1 is simplified.] 4y = 2 – 4z [equation b] step 3: 0 = 6 – 6z [equations in step 2 are added.] step 4: 6z = 6 step 5: z = 1 in which step did the student first make an error? (5 points) step 1 step 3 step 4 step 2 10. variable p is 2 more than variable d. variable p is also 1 less than variable d. which pair of equations best models the relationship between p and d? (5 points) p = d + 2 p = d – 1 p = d – 2 p = d + 1 d = 2p d = 2p – 1 d = 2p d = 2p + 1
