Actual cost = bill + VAT*bill
= bill*(1 +VAT)
= £463.20*(1 +0.20)
actual cost = £555.84
Answer:
<h2>A) y = -5x - 8</h2>
Step-by-step explanation:
The point-slope form of an equation of a line:
m - slope
(x₁, y₁) - point on a line
We have the slope m = -5, and the point (-1, -3). Substitute:
Convert to the slope-intercept form (y = mx + b):
<em>use the distributive property</em>
<em>subtract 3 from both sides</em>
Answer:
Step-by-step explanation:
step 1
Find the diameter of the circle
the formula to calculate the distance between two points is equal to
we have
substitute the values
step 2
Find the center of the circle
The center is the midpoint of the diameter
The center is equal to
step 3
Find the equation of the circle
The equation of the circle in center radius form is equal to
we have
(h,k)=(3,2)
---> the radius is half the diameter
substitute
Answer:
Step-by-step explanation:
hello :
the system is : x+ y =4 ...(*)
2x - y = -1...(**)
add(*) and (**) : 3x=3 so : x=1
put this value into (*) : 1+y=4 so : y=3
one solution : (1 , 3)
Answer:
Not Similer
Step-by-step explanation:
we can use the process of elimination, first AA isn't it because the corresponding angles arn't equal, next SSS itsn't it because we don't know the side lengths, and lastly SAS isn't it because we still don't know the side lengths.
