The correct question is:
A circle has a radius of 45 units and is centered at (-2.4, -4.8).
What is the equation of this circle?
Answer:
Equation of the circle is;
(x + 2.4)² + (y + 4.8)² = 2304
Step-by-step explanation:
The standard equation of a circle is;
(x - a)² + (y - b)² = r²
where;
(a,b) is the center of the circle and r is the radius of the circle
Now, from the question, the circle is centered at (-2.4, -4.8) and the radius is 45
Thus, plugging those values into the standard form of equation of a circle, we have;
(x - (-2.4))² + (y - (-4.8))² = 48²
This gives;
(x + 2.4)² + (y + 4.8)² = 2304
The perimeter of a rectangle is 2L + 2W, where L and W are the length and width, respectively. The dimensions of the garden are given, 6 x 12 ft.
The amount of fencing needed is 2(6) + 2(12) = 12 + 24 = 36 ft of fencing

sry idk the rest hope this helped a little bit
Answer:
y = 5-3x
Step-by-step explanation:
First, you want to divide both sides of the equation by 3, so we have the equation in the simplest form. Thus, we have an equation: 3x + y = 5.
Slope intercept form means the equation is in the y = mx + b form. In this case, y is y, m is 3 (coefficient of x) x is x, and b is 5. So, subtracting 3x from both sides means we have our answer of y=5-3x.
