Answer:
(a, 0)
Step-by-step explanation:
Point S has the same x-coordinate as does Point R: a.
Point S has the y-coordinate 0, as Point S lies on the x-axis.
Correct final answer: (a, 0) represents Point S.
Answer:
Step-by-step explanation:
The circle is divided into 5 sections. The probability that the needle lands on a particular color is equally likely.
So,
Probability of not blue = 1 - Probability of blue
Answer:
310
Step-by-step explanation:
A circle is 360 degrees
50 +x = 360
x = 360-50
x = 310
So to solve this you need to reverse factor this problem
x^2 + 8x + 7 = 0
The common formula is this for factoring ax^2 + bx + c
Now you have to think what multplties to "c" and adds up to "b".
So in this case it's 7 x 1 = 7 and 7 + 1 = 8
So you set it up like this
(x + 7)(x + 1) = 0
So now you can check the factors by multiplying them together and see if it gets your original equation which is does.
So finally to get the answers you need to set each parenthesis to 0 and solve for x.
x + 7 = 0
x + 1 = 0
and we get x = -1 and - 7
You can also plug these two answers back into your original equation to see if it equals 0.

Answer:
The coordinates of point X that divides the line in 1:4 are: (3,8/5)
Step-by-step explanation:
When a point divides a line with coordinates (x1,y1) and (x2,y2) in ratio m:n,
the coordinates of point are given by:
Given points are:
(x1,y1) = (5,1)
(x2,y2) = (-5,4)
Putting the values in the formula
Hence,
The coordinates of point X that divides the line in 1:4 are: (3,8/5)
