Answer:
100
Step-by-step explanation:
it is a bit unclear to me, what that problem description means.
if I understand it correctly, than z is directly depending on x².
so, z = 16 for x = 2. x² = 4
I pondered a little bit, as there are several possibilities to connect 16 with 4 as a driving factor (e.g. 2⁴ = 16, 4×4 = 16, 12 + 4 = 16).
I decided to go with the simplest interpretation with the usual meaning of "varies" (multiplication) : 4×x²
that would mean
z = 4×x² = 4×5² = 4×25 = 100
Answer:
Area of the dilation = 10.8 square inches
Step-by-step explanation:
Given the original dimension
Length = 12inches
Width = 10inches
If they are dilated by a factor of 0.3
New length = 0.3 * 12 = 3.6in
New width = 0.3 * 10 = 3in
Area of the dilation = 3.6 * 3
Area of the dilation = 10.8 square inches

Hello there. To solve this question, we'll have to see how to identify the difference between the two lines y = 0.5x (solid line) and y = x (the dashed line)
First, usually the solid line represents itself, all the values of y such that y = 0.5x.
In this case, for every value you take for x in the real line, you divide it by two and this will be its image, the line covers all the points satisfying this relation.
The dashed line usually represents inequalities, in this case, y is not equal to x.
When you have y > x, you have a dashed line and a shadowed region covering all the plane above the line.
When you have y < x, you have a dashed line and a shadowed region covering all the plane under the line.
When y is not equal to x, you only have a dashed line.
Therefore, the dashed line represents all the points in the plane such that y is equal to x, but excluding them in some sense.
