Answer:
(-1,-4)
Step-by-step explanation:
(2, -1)
Moving down 3 means subtract 3 from the y value
Left 3 means subtract 3 from the x value
(2-3, -1-3)
(-1,-4)
Hello!
We can put the x values in and see if we get y
Option 1:
Set A: y = 4x - 2
Do the first values
y = 4(-1) - 2
y = -4 - 2
y = -6
Look at the next one to be sure
y = 4(1) - 2
y = 4 - 2
y = 2
So the set A equation is correct we can look at set be now
y = x + 4
y = -5 + 4
y = -1
Try the next one to be sure
y = -2 + 4
y = 2
So the set B equation is also correct
The answer is the first one
Hope this helps!
Answer:
124.80
Step-by-step explanation:
price = $104.00
percentage deducted = 20%
price deducted = 104 × 20 ÷ 100
= 20.80
original price = 104.00 + 20.8 = 124.80
