Answer:
<em>3.9 kg</em>
Step-by-step explanation:
total mass = (number of nails) * (mass of one nail)
total mass = 750 * 5.2 * 10^(-3) kg
total mass = 750 * 5.2 * 10^(-3) kg
total mass = 750 * 0.0052 kg
total mass = 3.9 kg
Answer:
Step-by-step explanation:
two points on the line are (-3,-2) and (5,4)
slope=(4+2)/(5+3)=6/8=3/4
eq. of line is
y+2=3/4 (x+3)
4y+8=3x+9
4y=3x+1
y=3/4 x+1/4
To determine what the line looks like, simply change it to y = mx + b form. Then simply either make a table of values. And substitute any points into the equation and obtain points to plot on the graph. Or you can simply plot the graph by using the slope of the equation.
Y = 8 - 6x/2
Y = 4 - 3x
Y = -3x + 4.
This would be the rearranged equation.
Given :
