Answer:
A) (3,-8); Reflection
Step-by-step explanation:
The question kind of gave you a hint. Look at how the coordinate point is arranged...
(-y,-x)
That means all positive become negatives and all negatives become positives. This gives you the coordinate of (3,-8).
As for reflection or rotation, the image's coordinates FLIPPED, like how images do in a mirror's reflection.
This means the answer would be A) (3,-8); Reflection.
Answer:
y=-1/4x
Step-by-step explanation:
METHOD 1: The basic slope-intercept equation is <em>y=ax+b</em>. To achieve the slope with two points, this is the equation:
All you have to do is insert points (-4, 1) and (4, -1) into their corresponding locations.
With this equation, you will be able to find the slope. Then you can simply graph it to connect the two dots.
METHOD 2: Simply connect the two dots with a straight line (use a ruler or something with a straight edge.) Then count how many spaces up/down and left/right. If the line goes from top to bottom from left to right, it is a negative slope (hence, the -1/4.)
Answer:
-2 < x<4
Step-by-step explanation:
We have open circles and -2 and 4 so we don't include those numbers
The line is in between so the x is in between
-2 < x<4
Answer:
x< -1/4
Step-by-step explanation:
- 3/5 x + 1/5 > 7/20
Subtract 1/5 from each side
- 3/5 x + 1/5-1/5 > 7/20-1/5
-3/5x > 7/20 -1/5
Get a common denominator
-3/5x > 7/20 -1/5*4/4
-3/5x > 7/20 -4/20
-3/5x> 3/20
Multiply by -5/3 to isolate x
Remember that flips the inequality
-5/3* -3/5 x < 3/20*-5/3
x < -1/4
