Answer:
Point of intersections are (0, -7) and (5, -2).
Step-by-step explanation:
From the graph attached,
A straight line is intersecting the circle at the two points (0, 7) and (5, -2).
Now solve algebraically,
Equation of the line → y = x - 7 -------(1)
Equation of the circle → (x - 5)² + (y + 7)² = 25 -------(2)
By substituting the value of y from equation (1) to equation (2)
(x - 5)² + (x - 7 + 7)² = 25
(x - 5)² + x² = 25
x² - 10x + 25 + x² = 25
2x² - 10x = 0
x² - 5x = 0
x(x - 5) = 0
x = 0, 5
From equation (1),
y = 0 - 7 = -7
y = 5 - 7 = -2
Therefore, point of intersections are (0, -7) and (5, -2).
Answer:
15.60 times 100 divided by 390=4%
Step-by-step explanation:
Leeza can put 33 or less gallons of water in aquarium.
Step-by-step explanation:
Given,
Capacity of aquarium = 55 gallons of water
Water already in aquarium = 22 gallons
Let,
x be the number of gallons that can be added in aquarium.
As aquarium can hold 55 gallons of water, therefore, we cannot add more than 55 gallons of water.
Subtracting 22 from both sides
Leeza can put 33 or less gallons of water in aquarium.

The equation is -2x-4. u can use y2-y1/x2-x1.
Answer:
I dont really understand this notation, but it should be C or D. If the inequality includes 2, its C. If it doesn't include its D. Most likely it includes im guessing but Im not sure. So if you know how this notation works, its C or D. C for including 2 and D for excluding 2.
<h2><u>
Answer: Probably C but can be D</u></h2>
