Answer:
5/9
Step-by-step explanation:
5/6 x 2/3 = 5/9
9 tenths - 3 tenths = 6 tenths. this is true the same way that 9 minus 3 = 6. In reality the tenths make both numbers decimals, but in this case the "tenths" is just a classification of the number and it doesn't effect the answer.
Step 2: She did not simplify under the square root correctly
under the square root:
(-6)^2 =36
and -4(5)(-8) =160
therefore under the square root it needs to be square root of 36+160 which is square root of 196.
That answer is 14 when square rooted
The true equations are 24 over 2 squared equals 50 minus 6 squared minus 8 and 56 divided by 8 plus 3 squared equals 2 times 2 cubed.
The equation one is given as
39- 3(6) = 6(10/4)+4
After solving we get,
39 - 18 = 15 +4
21 = 19
Which is not a true equation.
2nd equation we have
24/(2^2)=50 -6^2-8
24/4 = 50 -36 -8
6 = 50 - 44
6 = 6
which is a true equation.
3rd equation we have
56/8+3^2= 2(2^3)
7 +9 = 2(8)
16 = 16
which is true equation.
4th equation, we have
8^2-5^2 = 4^2-7
16-10 = 16-7
6 = 9
Which is not a true equation.

Answer:
-21
Step-by-step explanation:
From the graph,
f(-4) = -3
and
g(-2) = 6
Hence,
-3 -3*6
= -3 -18
= -21
