Use PEMDAS, which stands for Parenthesis, Exponents, Multiply, Divide, Add, and Subtract.
First multiply, so 86 x 450 = 38700, and then divide 47 divided by 10, which is 4.7, and then add 4.7 plus 38700, which would give you 38704.7
The answer is - 1 and 11/12.
Answer:
The linear regression model is
.
Step-by-step explanation:
The given data points are (-6 4) (-4 0) (-3 -2) (-1 -7). Plot these points on a coordinate plane.
From the graph it is clear that the point are in the form of a straight line, so we need to use the linear regression model.
The general linear regression model is

Using technology we get


Put a=-2.19 and b=-8.92 in the above equation.

Therefore the linear regression model is
.
Use the pythagorean theorem to solve this: a^2 + b^2 = c^2.
You already have a and b which are 3 and 4. Square them up and you will get 9 + 16 = c^2.
Add.
25 = c^2
Lastly, square root both sides.
5 = c
The length of AB is 5.
Answer:
Step-by-step explanation:
4x + 7 = 3x + 14
x + 7 = 14
x = 7
4(7) + 7 + 3(7) + 14
28 + 7 + 21 + 14
35 + 35 = 70
