When a point is reflected across the x-axis, it's y value is flipped. Here is a formula for your future reference:
X-axis reflection: (x,-y)
Using your given coordinates, you simply plug the numbers in, resulting in final coordinates of (5,3.5).
Because the problem asks for the distance between the two points, you now have to find the difference between -3.5 and 3.5, which is 7.
There you go; the distance between the points is 7 units.
Answer:
There are two numbers 10 units from zero on the number line. These are 10 and -10.
Step-by-step explanation:
On a number line, if you move a pointer ten units right and left you will land on 10 and -10.
Answer:
D) 36 bottles for $4 by 1.4¢ per bottle
Step-by-step explanation:
We calculate bottle per dollar for each option.
#A
Bottles/Dollar=
bottles/dollar
#Both B and C charges the same as A and will have bottle/dollar ration of 8:1
#D

Hence, D is the better buy as it gives you 9bottles per $1 spent as compared to the 8 bottles per $1 spent as in the other 3 options.
Notice the picture below
due to equal sides on each scalene triangle, the angle bisector cuts the horizontal in half
thus, use the pythagorean theorem to get the "b" or opposite side

also notice, that "b" is also the altitude or height "h"
what's the area? well, area of a triangle is 1/2 bh
get the area of each triangle and sum them up, that's the area of the kite
Answer:
Step-by-step explanation:
1/6+1/4=5/12
5/12 of the job is done in 1 hour
so
5/12+5/12= 10/12
so 10/12 of the job is done in 2 hours
and then simplify 5/6 so then add 1/6
so it is done in 2 hours and 24 minutes
