Answer:
infinitely many solutions
Step-by-step explanation:
y = -2x -6 -----------------------------------------------------------------(1)
2y = -4x - 12---------------------------------------------------------------(2)
using elimination method
multiply equation (1) by 2
2y = -4x - 12 ----------------------------------------------------------------(3)
subtract equation (3) from equation (2)
0 = 0
Therefore the system of equation has infinitely many solutions

Answer:
5/4.75 or about 1.05
Step-by-step explanation:
y2-y1 /x2-x1 is the slope formula
8-3 = 5
5-1/4= 4.75
so 5/4.75 or simplified would be about 1.05
Answer: D. The range stays the same, but the domain changes.
Step-by-step explanation: A function can be reflected over or across an axis. When the function is reflected in the y-axis, it means:
g(x) = f(-x)
i.e, the x-values are opposite to the original function.
In the image below, when we reflected the function across the y-axis, the new one will be drawn at the positive x-axis but still at the negative y-axis as shown in red at the second attachment.
<u>Domain</u> of a function is all the values x can assume. <u>Range</u> of a function is all the results the variable y assume.
According to the new graph, <u>y-values didn't change, so Range stays the same. However, x-values changed their signal. Therefore, domain changes.</u>
Correct answer is D.
