Answer:
You did not show a picture so i can only help explain.
Step-by-step explanation:
When reflecting over the x-axis each point should have the same x coordinate and opposite y coordinate. For example from (9, 3) to (9, -3)
hope this helps!
For each 26 miles she needs 1 Gallon
For a distance of 2d , she will need x
Since the distance is proportional to the number of miles I can right:
2d/26 = 1/x or x =2d/26 or x=d/13
SIN(x) = .7547
X = INVERSE-SIN(.7547)
X = 49.0 degrees
Step-by-step explanation:
Here
5x+16+7x-3+6x+5 = 180(being sum of triangle)
or, 18x=180-18
or, x= 162/18
so, x = 9
now,
here,
<ACD = <ACB(diagonals of parallelogram bisect eachother)
or, <ACD = 7x-3
or, <ACD = 7×9-3
or, <ACD = 63-3
So, <ACD = 60°
Answer: B
Step-by-step explanation:
Insert the values of x and y for any point in the heavily shaded region and see if it satisfies both inequalities
We can see that the origin (0,0) is inside the shaded region so use these values because they are the easiest to compute
Plug in x = 0 and y = 0 into the first inequality
0 + 2.0 = 0 which is greater than 5.
So we can eliminate both A and D since they both contain incorrect inequalities
Now, test the second inequality with x = 0 and y = 0
For B we get
3.0 + 0 = 0 which is indeed less than 4
C is not applicable since 0 is not greater-than-equal to 4
Hence B is the correct solution
This can be verified using a graphing tool (see image)
