Answer:
Substitute in the values of both given coordinates & form 2 equations:

Find the value of B from the equation 2A - B = 1:

Substitute in the B-value to the other equation:

Find the B-value using the equation from before:
Therefore the equation Ax + By = 1 would equal:

Answer:
$109 and 35%
Step-by-step explanation:
49.05 is the sale price and the discount is 55%. What’s the original price?
price/ 1- discount
49.05/ 1 - 0.55
49.05/ 0.45

to find the discount subtract final price from original price
94 - 61.10 = 32.9
Which would be 35% in percent form.
Answer:
What the hell AC is not given so you can't find the Perimeter
Step-by-step explanation:
x+10=0
x=-10
AB=x+5
AB=-5
BC=x-2
BC=-12
Area of ABC = 30cm2
<u>Perimeter of ABC = AB+BC+</u><u>AC</u>
