Answer:
.
Step-by-step explanation:
Given:
center (7,-3)
radius = 9
Equation of the circle:
(x-h)² + (y-k)² = r²
(x-7)² + (y-(-3)² = 9²
(x-7)² + (y+3)² = 81 Last option.
Answer:
5:3
Step-by-step explanation:
Given that the chemist mixed 5 mL of Solution A with every 3 mL of Solution B to make a new solution with a new concentration.
So, the amount of Solution A in the mixture, a = 5 mL
The amount of Solution B in the mixture, b = 3 mL
Therefore, the ratio of Solution A to Solution B in the new solution with the same concentration is a:b=5:3.
Hence, the required ratio for the same concentration is 5:3.
Please note that none of the given options matched.
You just multiply g(x) and f(x) together and it gives you C :)
Rewriting this <span>7-y=5x+11 in standard form involves only changing the order in which the terms appear:
</span><span>7-y=5x+11 becomes 5x + y + 11 - 7 = 0, or 5x + y + 4 = 0, or 5x + y = -4.</span>
