She made an error in step 1.
Step-by-step explanation:
Answer:
f(-4) = -2
Step-by-step explanation:
To find f(-4) use the "piece" of the function rule defined for x < -3 (because -4 is less than -3). That part of the rule says the output (range) value is x + 2, so f(-4) = -4 + 2 = -2.
Answer:
Option 2
Step-by-step explanation:
6(a)-6(3)=6a-6×3=6(a-3)
Answer:
x=23, y=157
Step-by-step explanation:
23 and x are on equalivent sides of the rhombus so they are equal. To solve for y you have to multiple 23 by 2. Getting 46 you subtract that from 360 to get 314. Dividing 314/2 you get 157.
