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 β4.
multiply equation b by 2.
9.
the work of a student to solve a set of equations is shown:
equation a: y = 4 β 2z
equation b: 4y = 2 β 4z
step 1: β4(y) = β4(4 β 2z) [equation a is multiplied by β4.]
4y = 2 β 4z [equation b]
step 2: β4y = 4 β 2z [equation a in step 1 is simplified.]
4y = 2 β 4z [equation b]
step 3: 0 = 6 β 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 β 1
p = d β 2
p = d + 1
d = 2p
d = 2p β 1
d = 2p
d = 2p + 1
