Answer:
there should only be two points at 6 and 4
Step-by-step explanation:
[x-5]=1
x-5=+ 1 or -1
x-5= 1
x-5= -1
x=6 or 4
Answer:
(x + 6)² + (y - 2)² = 75
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
here (h, k) = (- 6, 2) and r = 5
, hence
(x - (- 6))² + (y - 2)² = (5
)², that is
(x + 6)² + (y - 2)² = 75
Answer:

Step-by-step explanation:
<u><em>The complete question is</em></u>
Suppose that a new fuel-efficient European car travels an average of 28 kilometers on 1 liter of gasoline. If gasoline costs 1.50 euros per liter, how much will it cost to drive 220 kilometers ?
step 1
using proportion
Find out the number of liters of gasoline needed for 220 kilometers
so

step 2
Find the cost to drive 220 kilometers
Multiply the cost of one liter of gasoline by the total liters of gasoline needed to travel 220 Km
so
