She underestimated by 60 cents. To get this answer all you need to do is multiply 1 dollar times 12 which is $12 and then multiply $.30 by 12 and that gives you $3.60. Then you add the $12 to the $3.60 and that gives you $15.60 which is 60 cents over the estimation.
<span>How to graph {3x-8y = 29 3x+y = -2}
</span> The first thing you should do is to clear "y". Then, you must substitute values of x in the equation to find the values of "y". Finally, graph the points obtained. (see graphic)
How do you convert this to slope intercept form? 3x-8y = 29 ---> y = 0.375x - 3.625 3x+y = -2 ---> y = -3x - 2

Answer:
x = 48
Step-by-step explanation:
14^2 + b^2 = 50^2
196 + b^2 = 2500
-196 -196
b^2 = 2304
√b^2 = √2304
b = 48
