Answer:
D. 
Step-by-step explanation:
we are given
Firstly, it is reflected over x-axis
we know that for reflection about x-axis , we can replace y as -y
we get
now, it is vertical shift up by 4 units
so, we can add 4 to y-value
we get
Answer:
C =28.26m
Step-by-step explanation:
We are walking around a circle, which means we are finding the perimeter. The perimeter of a circle is called the circumference.
We find the circumference by
C = pi *d where d is the diameter
C = 3.14 * 9
C =28.26m
Answer:
You must add 9/4 in order to make this a perfect square.
Step-by-step explanation:
To make any binomial into a perfect square trinomial, you have to take the middle term (-3), cut it in half (-3/2) and then square it (9/4). This will give you the constant to make a perfect square trinomial every time.
Answer:
B) f(x) = -3/5x +5
Step-by-step explanation:
There are several ways you can write the equation of a line from a list of points. When you look through the list and see that one of them is the y-intercept, then the problem can be easier. When you look through the list of answers and see that the required answer is in slope-intercept form, then you know all you need to do is find the slope to go with the intercept you've located.
The point (x, f(x)) = (0, 5) tells you the y-intercept is 5.
The slope, the change in y divided by the change in x for two points, is ...
... (-1 -2)/(10 -5) = -3/5
This is the slope and the coefficient of x in the linear equation.
Now, we know the y-intercept (b=5) and the slope (m=-3/5), so we can fill in the slope-intercept form of the equation of a line:
... y = mx + b
... y = (-3/5)x + 5
