The answer is C.

33,21,and 15 are all composite numbers. Meaning that they had factors other than 1 and themselves. 13 is a prime number because 13 only factors are 1 and itself.

Line a is parallel to line b, m∠1=2x +44, and m∠5x+38. Find the value of x.
Soloha48 [4]

2x + 44 = 5x + 38
5x - 2x = 3x
44 = 3x + 38
44 - 38 = 6

How are basic facts can help you find 10*20*30*40 mentally
Lena [83]
When you do the multiplication you can notice that 10, 20, 30, 40 all have 0's at the end.

So that means 10 *20*30*40 = 1*2*3*4*10000 = 24*10000 = 240,000

What is the inverse of the function f(x) = x +3?
Yanka [14]

Answer:

C)h(x) = x-3

Step-by-step explanation:

To find the inverse of a function, switch the "x" and "y" values, then isolate for "x".

f(x) is the y value.

y = x + 3

x = y + 3   Switch x and y

x - 3 = y     Subtract 3 from both sides to isolate

y = x - 3   Change back to function of h

h(x) = x - 3
