How much do they pay him an hour. Justify your question please?
Answer:
The first one, the third one, and the fourth one
Step-by-step explanation:
The 1st one is the Pythagorean identity. One of the most essential trig identities you have to remember.
The second one is false because A is equal to 60 and b is equal to 30 and the left side turns into 0.5 while the other side becomes -0.5.
The third one is true since it is a distinction of the identity = (OR you can simply just subtract from either side).
The fourth one is true since it's just a different version of .
I do not think so, but i’m not 100% sure
Answer:
This equation is invalid, the left and right sides are not equal, therefore there is no so
Step-by-step explanation:
Simplifying
5 + 2y = 13 + 2y
Add '-2y' to each side of the equation.
5 + 2y + -2y = 13 + 2y + -2y
Combine like terms: 2y + -2y = 0
5 + 0 = 13 + 2y + -2y
5 = 13 + 2y + -2y
Combine like terms: 2y + -2y = 0
5 = 13 + 0
5 = 13
Solving
5 = 13
Couldn't find a variable to solve for.
This equation is invalid, the left and right sides are not equal, therefore there is no so
Answer:
the slope is over 3 then down 3 or 3/-3
step explanation: first find the y-intercept (9) then normal you just count the number of spaces over or back then up or down
