Answer:
B, C, and F
Step-by-step explanation:
y = 1/2x
y = 1/2(4)
y = 2
y = 1/2x
y = 1/2(-2)
y = -1
y = 1/2x
y = 1/2(2)
y = 1
A) 3.5
B) 9.8666

8n=40-16
8n=24
n=3
Answer:
-2x + 3
Step-by-step explanation:
Step 1: Write out expression
-1/5(5x + 20) - 1/4(4x - 28)
Step 2: Distribute
-1/5(5)x - 1/5(20) - 1/4(4)x + 1/4(28)
Step 3: Multiply
-x - 4 - x + 7
Step 4: Combine like terms
-2x + 3
Answer:
The least common denominator would be 28.
Mutiply by 7 for 3/4.
Mutiply by 2 for 5/14.
3(7)/4(7)= 21/28, 5(2)/14(2)= 10/28
