Step-by-step explanation:
<u>Step 1: Define</u>
f(x, y) = 2x - 3y + xy²
(3, -1) is x =3 and y = -1
<u>Step 2: Evaluate</u>
- Substitute: f(3, -1) = 2(3) - 3(-1) + 3(-1)²
- Exponents: f(3, -1) = 2(3) - 3(-1) + 3(1)
- Multiply: f(3, -1) = 6 + 3 + 3
- Add: f(3, -1) = 9 + 3
- Add: f(3, -1) = 12
If l || m than 8x+20=11x-31
3x=51
x=17
The angles are obtuse angles.
Answer:
(A) - 4t
Step-by-step explanation:
5t + (t - 3) - [(7t + 5) - (8 - 3t)] =5t + (t - 3) - [7t + 5 - 8 + 3t] =
= 5t + (t - 3) - [10t -3 ] = 5t + t - 3 - 10t + 3 = - 4t
Answer : 50 degrees
Explanation : Every triangle equals a total of 180 degrees. Use this fact to create an equation to solve for x. Add all expressions together.
You would get the equation 3 1/3x = 300
x = 90
Then plug x into the equation x - 40 to find the angle of A. This gives you 50.
Answer:
Probably 80* (* means degrees for me) i might be wrong
Step-by-step explanation:
So if m<1 = 50* and m<2 = 65, then there might be a pattern.
50 + 15 = 65. So if 65 + 15 = 80, then 80* MIGHT be the answer.
