Answer:
Janelle's height is 82 units.
Step-by-step explanation:
Let j represent Janelle's height.
It is mentioned that, 58 is the difference between Janelle's height and 24.
Mathematically, we can write it as :
j-24 = 58
We can solve it as follows :
Adding 24 both sides,
j-24+24 = 58+24
j = 82
Hence, Janelle's height is 82 units.

Answer:
58. 2 real roots; see attached for a graph
59. -6, 3
Step-by-step explanation:
58. A graphing calculator graphs this easily. The graph is shown in the attachment. There are 2 x-intercepts, hence 2 real roots.
__
59. The x-intercepts are (-6, 0) and (3, 0), so the x-values x=-6 and x=3 satisfy the equation y = 0.
Answer:
.36

Answer/Step-by-step explanation:
4(x - 2)= 100 and 2(x - 2) = 50.
We can determine that in both equation x equals 27. But, why is the second one half as much as the first problem? This is because the second problem is being multiplied with a number half as large as the first. Since 27 - 2 = 25 and 25 x 4 = 100 and 25 x 2 = 50 these problems hold up to their function.
If x = 27:
<u>4(x - 2) = 100</u>
27 - 2 = 25
25 x 4 = 100
<u>2(x - 2) = 50</u>
27 - 2 = 25
25 x 2 = 50
