Answer:
3x + 7
Step-by-step explanation:
For this case, the first thing we must do is define a variable.
We have then:
x: unknown number
We now write the expression that models the problem:

From here, we clear the value of x.
We have then:




Answer:
4/9 divided by 1/27 equals 12
Answer:
134
Step-by-step explanation:
Angle Formed by Two Chords= 1/2(SUM of Intercepted Arcs)
x = 1/2 ( m DH + m BC)
x = 1/2 (144+ 124)
x = 1/2 ( 268)
x = 134
Answer:
Angle IEF = Angle CEH ( corresponding)
Therefore Angle CEH = 96°
Answer:
Linear approximation is given by: 
Step-by-step explanation:
We are given the following information in the question:
Number of citations: 5 7.5 10 15 20
Outputs Residuals: 3 6 10 5 6
We have to find the linear approximation of the data that passes through the points (5, 3) and (20, 6).
Linear approximation is given by:
The equation of line is given by:

where,
is the point through which the line passes.
The equation of line is:

The above equation is the required linear approximation.
