You want to write this equation in the form (x+...)(x+...) (maybe with a minus sign). To do this, find numbers that, when multiplied, give 16, and when added give -10.
What whole numbers give 16?
1*16 and -1*-16
2*8 and -2*-8
4*4 and -4*-4
Which of these solutions, when changed into a sum, give -10?
Try them one by one and find it is:
-2-8 = -10.
So (x-2)(x-8) is the factorization!
This is really a bit of trial and error, but since most of the time the assignments deals with whole numbers, there aren't that many possibilities.
Ratio = 2:3 = 2/5
Distance between the x coordinates: 3
Distance between the y coordinates: 7
x: 3 * 2/5 = 1.2
y: 7 * 2/5 = 2.8
x coordinate of point: 6 - 1.2 = 4.8
y coordinate of point: 1 + 2.8 = 3.8
So the point that divides the segment AB in the ratio of 2:3 is (4.8 , 3.8) or (24/5 , 19/5)

Answer:
153.94
Step-by-step explanation:
The formula for the area of a circle is
A =
If the diameter is 14 in the to get the radius all you have to do is divide it by 2 to get 7
R is radius
R = 7
plug in 7 for R in the equation
*
and you will get 153.94
Answer:
y = 90x + 50
Step-by-step explanation:
In this situation, let's define the variable and the constant.
The variable is what changes, so in this case the wage ($90) changes with how many hours the electrician is hired for.
The constant is the number that stays the same, in this case it would be the $50 traveling fee because it remains the same every time.
The equation should be written in this form:
y = mx + b
m = slope (variable)
b = y-intercept (constant)
Therefore, you can write the equation like this:
y = 90x + 50

Answer:
48,58
Step-by-step explanation:
Let The speed of the west bound train be x
Let the east bound train be x+10
The speeds can be calculated as follows
2(2x+10)= 232
4x + 40= 232
4x= 232-40
4x= 192
x= 192/4
= 48
Hence the speedof the west bound train is 48
The speed of the east bound train is 48+10
= 58
