X=-2
4(3x+2)=-16
————
4
Divide by 4 on both sides
3x+2= -4
-2 -2
Subtract 2 on both sides
3x=-6
Divide both sides by 3 to isolate x
x=-2
Conversion: 1 mile = 1,760 yards
Multiply.
2.5 * 1760 = 4,400
Therefore, there are 4,400 yards in 2.5 miles.
Best of Luck!
<span>When you have an equation of the form y = mx + b (which you do in this case), the slope is always equal to the coefficient of x, which is m or 12 in this case. Since there is no "b" in your equation, you could say that b=0, and the line is known to cross the y axis at zero.
In case you are interested, if the equation said y = 12 x + 3 the slope of the line would still be 12 but the line would cross the y axis at 3. If the equation said y = 12x -4, the line would have a slope of 12 and would cross the y axis at -4.</span>
