Step-by-step explanation: Vertical Line test will determine if a graph is a function or not
Complementary angles are two angles whose measures add to a sum of 90 degrees. This can be expressed as the following formula:
A1 + A2 = 90
Substitute any known values into the equation above:
(2x + 1) + (x – 7) = 90
2x + 1 + x – 7 = 90
Combine like terms:
3x – 6 = 90
Add 6 to both sides of the equation:
3x = 96
Divide 3 from both sides of the equation:
x = 32
When (2x + 1) and (x – 7) are complementary, “x” is equal to 32.
I hope this helps!
Very easy:
put the 10 and 12 end to end then back off the 7 inches
22-7 = 15
Step-by-step explanation:
a^2 + b^2 = c^2
a = 6
b = x
c = 11
6^2 + b^2 = 11^2
36 + b^2 = 121
b^2 = 121 - 36
b^2 = 85
Find the square root of both sides.
b = 9.22
.16
It‘a really easy just do
20 divided by 125
