Add the angles and minus the total from 180 that will be the answer
Answer:
(-1, 9) (he x value is placed first).
Step-by-step explanation:
y = -3x + 6
y = 9
Substitute y = 9 into the first equation:
9 = -3(x) + 6
-3x = 9 - 6
-3x = 3
x = -1.
Answer:
5/12
Step-by-step explanation:
The whole book is 1.
So This will be your equation.
1/3 + 1/4 = 1
4/12 +3/12 = 1
7/12 = 1
Now you minus 7/12 from 1
1-7/12 is how much is left
12/12-7/12= 5/12
Answer: simplified down to 25/28 or 0.89 / / 0.9 rounded up
(2x³ - 5x² + 8)(x + 3) = ?
First step is to distribute.
2x^4 + 6x³ - 5x³ - 15x² + 8x + 24
Now combine like terms.
2x^4 + x³ - 15x² + 8x + 24
This is your answer, since you can't simplify any further or solve it without some more information.
