Answer:
Mostly correct
For Q3, you are doing great, you remembered that negative numbers can happen if the exponent is an odd number.
For Q4, I think you were confused with the fractions,
4(i)
4(ii) is also wrong but I'll let you try to fix it yourself following what I given you for 4(i). You should get 1/64
Hope this helps!
Answer:
-4(2+i)
Step-by-step explanation:
-8-4i (can factor out a 4)
-4(2+i)
Answer:
-15x + 30
Step-by-step explanation:
Using the distributive property, distribute -3 to the parentheses:
-3(5x) = -15x
-3(-10) = 30
Add these terms together:
-15x + 30 is the rewritten expression
Answer:
see below. × signifies a wrong choice; → signifies a correct one
Step-by-step explanation:
× Jorge should graph in the vertical line with values of –4 for the line of reflection. (The line of reflection is horizontal.)
→ Jorge could count how far each pre-image point is from the line of reflection along the perpendicular from the point to the line of reflection.
× Jorge could count how far each vertex of the figure is from the y-axis and count the same distance on the other side. (He could do this pointless exercise, but it has no relation to the problem. The y-axis (x=0) is not the line of reflection.)
→ Jorge will not move any point that lies on the line of reflection. (All points on the line of reflection are reflected to themselves.)
→ Jorge could check his work by seeing if each segment joining a pre-image point with its image has the midpoint on the line of reflection. (This is what is meant by "line of reflection.")
× Jorge could check his work by making sure that the image has the same orientation as the original. (A reflected image as an orientation opposite that of the original, a fact you see every time you look in a mirror.)
