= 1/5 + (-2/3) = -7/15
(A rational number is a number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q. Rational number can be both positive and negative.)
Answer:
A. cos(t)= 1/sec(t)
Second answer is C. 12/13
Step-by-step explanation:
Just had the question.
Answer:
1373 r 4
Step-by-step explanation:
Answer:
x = 35 degrees.
Step-by-step explanation:
These are 2 'same side' interior angles of a parallelogram whose sum is 180 degrees.
So we have th equation:
3x + x + 40 = 180
4x = 180 - 40
4x= 140
x = 140 / 4 = 35 (answer)>
Numbers 27 and 81 have 27 as common factor which is equal to 3^3. Noting that we can put 27 before brackets write it in form 3^3 and that third root and cube will trim.
![\sqrt[3]{27x - 81} - 5=](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B27x%20-%2081%7D%20%20-%205%3D)

-5 means that graph is shifted 5 to down.
-3 means it is shifted to right by -3
3 and ∛ represent scaling of graph which can be seen and tested once you draw it. It is harder to explain it with words.
