Answer:
(x - 2)^2 + (y + 3)^2 = 49.
Step-by-step explanation:
The circle will have the equation:
(x - 2)^2 + (x + 3)^2 = r^2 where r = the radius and (2,-3) is the center..
To find r^2 we use the distance formula ( the radius is the distance between the center and the point (9,-3):
r^2 = ( 9 - 2)^2 + ( -3 - (-3)^2
r ^2 = 7^2 + 0^2
r^2 = 49.
The answer is (x - 2)^2 + (y + 3)^2 = 49.
Answer:
3.2t - 2.4
Step-by-step explanation:
- 3.6 - 1.9t + 1.2 + 5.1t ← collect like terms
= (- 1.9 + 5.1)t + (- 3.6 + 1.2)
= 3.2t + (- 2.4)
= 3.2t - 2.4
Answer:
Mia scored 6 baskets Last Saturday.
Step-by-step explanation:
Let:
Mia made score of baskets on Last Saturday = x
Mia made score of baskets yesterday = 3x (Mia made three times as many baskets in yesterday’s basketball game as she did last Saturday. three times means multiply 3 with score of Last Saturday baskets, i.e. x)
Total score of baskets = 24
We need to find How many baskets did Mia score last Saturday?
We can write:
<em>Total Score = Score on Last Saturday + Score yester</em>day
![24=x+3x](https://tex.z-dn.net/?f=24%3Dx%2B3x)
Solving this equation we can find value of x:
![24=x+3x\\24=4x\\=>4x=24\\x=\frac{24}{4}\\x=6](https://tex.z-dn.net/?f=24%3Dx%2B3x%5C%5C24%3D4x%5C%5C%3D%3E4x%3D24%5C%5Cx%3D%5Cfrac%7B24%7D%7B4%7D%5C%5Cx%3D6)
So, we get value of x = 6
Mia made score of baskets on Last Saturday = x = 6
Mia scored 6 baskets Last Saturday.
