Answer:
the answer may be 127.
Step-by-step explanation:when you add 90° + 37° you will get the answer 127
I am not sure.
Answer:
(4, -6), (-10, -6), (-3, 1), (-3, -13)
Step-by-step explanation:
If we add/subtract t to/from any x/y coordinate, we will form a line segment with length 7. Hence, (4, -6), (-10, -6), (-3, 1), (-3, -13).
Answer
Sol: The correct answer is b. three planes that contain point B are ABD, AEF and DHF.
First do PEMDAS
There's no parenthesis. So move on to exponent. There's also no exponents. Move on to multiplication. There it is.
12×5=60.
There's no division so now next one is addition. Hey look! There is addition.
60+55=115.
So 115 is your answer.
Have you learned matrices yet? I'm going to use that to solve these, please refer to the photos.
I solved the system by using a matrix calculation. The work always needs to be shown and you do that by setting up the matrix like in the first photo and also writing out all your equations. In a TI calculator, to do this you press 2ND-X^-1,GO TO EDIT - [A] - 3×4- now enter the coefficient of the system of equations variables. NOW 2ND MODE- 2ND-X^-1 -GO TO MATH- ALPHA APPS
Now, if you don't know this you may be confuse so after rref([A]) was enter a matrix came up with [1 0 0 -21] in the top row this means x equal -21. So, the next row is y and it came out as [0 1 0 46] so y equals 46 and I'm going to let you figure out what z is by looking at the matrix.
SO... X=-21 Y=46 and Z=-10
Let's Test it
