(4x+7)/5 = 58
Cross Multiply:
4x+7 = 5*58
4x + 7 = 290
Subtract 7 from both sides:
4x = 283
Divide by 4 on each side:
x = 70.75
D) 70.75! :)
Answer:

The definition of estimated sum and the actual sum are these: estimated sum means to form an approximate judgment of the total of 2 or more numbers. A<span>ctual sum means the real total of two or more numbers.</span>
If we have the directrix at x = -3 (a vertical line) and the focus at (3, 0), then the vertex of the parabola is between these two, at the origin (0, 0). The parabola itself opens in the direction of the focus, which is to the right. The general equation for a parabola opening to the right is x^2 = 4cy, where c is the distance from the vertex to the focus (or to the directrix). In this case, c = 3 (from (0,0) to (3,0)). Therefore, the equation is x^2 = 12y, which is identical to y = (1/12)x^2, choice A.
the answer is: 83,229 (the least) , 283,299, 823,299 ( the greatest)
