Step-by-step explanation:
So if you are reflecting across the x-axis then the point after the reflection should be (x,-y). If you are reflecting across the y-axis the the point after the reflection should be (-x,y). If you are reflecting across the line y=x, then the point after the reflection should be (y,x) If you are reflecting across the line y=-x, then the point after the reflection should be (-y, -x). If you are reflecting across the origin, then the point after the reflection should be(-x,-y). Hope this helps.
Answer:
y=1x-9 That's the equation if you're trying to figure that out and the slope would be 1/1
I'm sure there's an easier way to do this, but this method does work:
First, AB = CD = CG + GF + FD, so FG = 2.
By the Pythagorean theorem, in triangle AFD we get
and in triangle BCG,
Angles AFD and EFG form a vertical pair, so they are congruent and have measure
Similarly, angles BGC and FGE are congruent and have measure
Then the remaining angle in triangle EFG has measure
We can solve for the lengths of FE and GE exactly by applying the law of sines:
Let 
be the semiperimeter of triangle ABE, so that
Then according to Heron's formula, the area of triangle ABE is
Answer:
9x miles
Step-by-step explanation:
Distance covered per day = x mile per day
Number of days = 9days
Unknown:
Distance covered for 9 days = ?
Solution:
This is a simple problem.
Since Kinsey covered a distance of x mile/day, in 9 days:
x mile is covered in 1 day;
1 day, Kinsey covers x mile
9 days, she will cover 9 x (x) miles = 9x miles
Answer:
The answer is B.
Step-by-step explanation:
There are two shirts, both cost 10.
10 + 10.
The variable is the cost of the hat, which we add on.
10 + 10 + x.
Finally, 50 is the total price so that is going to be what it equals.
10 + 10 + x = 50
