Answer:
C
Step-by-step explanation:
m+x=500
0.3m+0.1(x)=500*0.25
x=500-m
0.3m+(0.1(500-m))=0.25*500
0.3m-0.1m+50=125
0.2m+50=125
0.2m=75
m=75*5
m=375

more than the quotient of -36 and -4 is called a word statement.
Thus, we need to convert it into its algebraic equation and then solve.
Before that, let’s identify each word first
=> 9 is an integer
=> more than = means add or +
=> quotient = means answer to division
=> - 36 and -4 are negative integers
Now, let’s make the equation
=> 9 + (-36 / -4 ), since both numbers to be divided are negative, the quotient
would be positive
=> 9 + 9
=> 18

Answer:
y = -2.8x +69.4
Step-by-step explanation:
The 2-point form of the equation of a line can be used to find the equation of the line through points (3, 61) and (13, 33). The general form of it is ...
y = (y2-y1)/(x2-x1)·(x -x1) +y1
For the given points, this is ...
y = (33 -61)/(13 -3)·(x -3) +61
y = -28/10(x -3) +61
y = -2.8x +69.4 . . . . . the equation of the line through the given points

<em>Comment on the problem</em>
A "line of best fit" is one that minimizes some measure of deviation from the line. Usually, what is minimized is the square of the deviations. Choosing two points to draw the line through may be convenient, but does not necessarily result in a line of best fit.
