Step-by-step explanation:
R = 3x + 9y
When y = 6 and R = 7
7 = 3x + 9.6
7 = 3x + 54
7 - 54 = 3x
-47 = 3x
x = -47/3
Answer:
Choice 1
Step-by-step explanation:
Let‘s go through each answer and analyze a
each.
<u><em>Choice 1</em></u>
<u>Parallel</u> means to lines with the same slope, they never intersect, ever, they always remain next to each other and never touch. This is true for the picture
<u><em>Choice 2</em></u>
<u>Perpendicular</u> means that two lines intersect at a right angle, however upon looking at the picture you can see this is not a right angle, but an acute angle. So it is not perpendicular.
<u><em>Choice 3</em></u>
A <u>Line Segment </u>means a line with dots on either end, symbolizing the end of the line. This is not a line segment because there are arrows on the ends, indicating these lines go on forever. This is not a segment
<u><em>Choice 4</em></u>
We already determined this is neither a segment nor perpendicular so it cannot be this choice
This leaves us with Choice 1.
I hope this helps!

Answer:
38
Step-by-step explanation:
Given that,
x = -4
f(x)=x² - 4x +6
so,
f(-4)= (-4)² - 4 . (-4) +6
=16 +16 +6
= 38
