The average weight is 114 pounds of all 5 children.
3 * 120 = 360
2 * 105 = 210
210 + 360 = 570
570 / 5 = 114

Math help, I'm stuck with my homework and I want to get it done.

Answer:

m = $\frac{1}{4}$

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 4x + 7 is in this form with slope m = - 4

Given a line with slope m then the slope of a line perpendicular to it is

$m_{perpendicular}$ = - $\frac{1}{m}$ = - $\frac{1}{-4}$ = $\frac{1}{4}$

Hence the value of m = $\frac{1}{4}$
