−7 ≤ x ≤ 4
Step-by-step explanation:
Answer:the answer is a
Step-by-step explanation:
Given:
Consider the below figure attached with this equation.
To find:
Length of side ZX.
Solution:
From the figure it is clear that, WXY is a right angled triangle.
According the 30°-60°-90° theorem, the longer leg (opposite to 60° angle) of the right-angled triangle is
times of shorter leg (opposite to 30° angle).
In the below figure, WY is longer leg and XY is shorter leg.



So, the length of XY is 8 units.
VWYZ is a rectangle, so

Now,



So, the length of ZX is 18 units.
Therefore, the correct option is C.
Answer
(0,-4) and (4,0).
Step-by-step explanation:
The solutions of a system of equation from a graph is where the graphs intersect.
From the question, you mentioned that the graphs intersect at (0,-4) and (4,0).
Therefore the solutions to the system are (0,-4) and (4,0).
Probably, you might have a straight line and a quadratic graph interesting or two quadratic graphs.
