Very easy:
Since there is no involvement of y so simply draw a vertical line at x=1.And shade the part which is describing the x values.
Hence,
You will shade all the part which is on the left of the vertical line.As there is an equal sign too,so the vertical line will be a solid line instead of dotted line.
See the attachment for graph.
I'm going to rewrite f(x) and g(x) so that I don't get confused.
Based on your description:
f(x) = (2x)
+ x - 1 simplified to 4x
+ x - 1
g(x) = x
+ 3x - 3
Now we handle parts A-D.
A. f(x) + g(x)
We combine like terms.
4x
+ 5x
+ x + 3x - 1 - 3 = 5x
+ 4x - 4
B. f(x) - g(x)
Again combine like terms like normal except this time subtracting.
4x
- x
+ x - 3x - 1 - (- 3) = 3x
- 2x + 2
C. 2f(x) + 2g(x)
Multiply, then again CLT
2f(x) = 8x
+ 2x - 2
2g(x) = 2x
+ 6x - 6
Combine like terms to get 10x
+ 8x - 8
D. 2f(x) - 2g(x)
Use the same 2f(x) and 2g(x) terms and this time just subtract.
You get 6x
- 4x + 4
Answer:
Option C
Step-by-step explanation:
See here the net seems like a equilateral triangle
- And another equilateral traingle is inscribed in it
- So 4 equilateral triangles
Hence option C
Answer:
x = -6 and y = -9
y = 0
Step-by-step explanation:
A vertical line is an x = equation. No matter what y equals, x will always be -6, so it's x = -6. A horizontal line is a y = equation. No matter what x equals, y will always be -9, so it's y = -9. Finally the equation of the x axis is simply y = 0 since any point on that horizontal line has a y coordinate of 0.
