Answer:
Step-by-step explanation:
The pizza shop is offering two pizzas for the same price.
The round one is 12 inches in diameter. To know the size of the round pizza, we will determine its area. It is the same as the area of a circle which is expressed as
Area = πr^2
Radius, r = diameter /2 = 12/2 = 6 inches.
π = 3.14
Area = 3.14 × 6^2 = 3.14 × 36 = 113.04 inches square.
To know the size of the square pizza, we will apply the formula for a square
Area = l^2
Since one side is 10 inches,
The area is 10.5 × 10.5 = 110.25 inches square.
It means that the round pizza is bigger. She should by the round pizza
The slope-intercept form:
m - slope
b - y-intercept
We have the points (1, -5) and (9, 11). Substitute:
Therefore we have
Put the coordinates of the point (1, -5) to the equation:
<h3>Answer: y = 2x - 7</h3>
Answer:
Step-by-step explanation:
hello :
x2 plus y2-6x plus 2y equals 6 means :
x²+y²-6x+2y =6
(x²-6x)+(y²+2y)=6
(x²-6x+9 -9 )+(y²+2y+1-1) = 6
(x-3)²-9 +(y+1)²-1 = 6
(x-3)²+(y+1)² = 4²
standard form when the center is : (3;-1) and length of the radius is :4
