Answer:
c = 5
Step-by-step explanation:
- 6 + 2c = 3c -(6+5)
-6 + 2c = 3c -11
-6 + 11 = 3c- 2c
5 = c
Answer:
Slope=2
Step-by-step explanation:
Slope=rise/run
We can start at 2, 3 (you can start anywhere on the line)
Then go to 3, 5 (you can end anywhere on the line)
Rise=2
Run=1
2/1=2
Slope is 2. The uses up there were examples. It doesn't have to be the exact points.
Answer:
The vertex would be (1, -7/10)
Step-by-step explanation:
In order to find the vertex, start by finding the x-coordinate. The x-coordinate can be calculated using -b/2a, in which a is the coefficient of x^2 and b is the coefficient of x.
-b/2a
-(-2)/2(1)
2/2
1
Now that we know the value of the x-coordinate as 1, we can use it in the equation to find y.
y = x^2 - 2x + 3/10
y = (1)^2 - 2(1) + 3/10
y = 1 - 2 + 3/10
y = -7/10
Well to find the area you have to multiply 3.14 by your radius. Then you square it.
