Answer:
C= to find x, add the given angles
Step-by-step explanation:
Answer:
The value of c that completes the square
is 1
Step-by-step explanation:
We need to find the value of c that completes the square 
The formula used will be: 
In the question given the value c can be found by breaking the middle term. we are given 2x while the general formula is 2ab for middle term so,
2(x)(1) = 2x
so, c= 1
Solving:

So, the value of c that completes the square
is 1
Answer:
56.25 pi cm^2
Step-by-step explanation:
To find the area of the circle,
we use the formula
A = pi r^2, where r is the radius
We know the diameter is 15 so we can find the radius from
r = d/2 where d is the diameter
r = 15/2
A = pi ( 15/2) ^2
A = pi ( 225/4)
A = 56.25 pi cm^2
Recall that a slope-intercept form of a linear equation is

Rearrange the given so that it follows that slope intercept form

The y-intercept is the value for which the linear function crosses the y-axis, this is when the value of x is equal to zero. The ordered pair therefore of the y-intercept is (0,-1).
Answer:
Function 1 is linear
Step-by-step explanation:
A linear is a straight line on the graph.
