Answer:
-66
Step-by-step explanation:
P(8) = -8^2 - 2
-64 -2 = -66
Answer:
Step-by-step explanation:
4x + 3y = -1 --------------(i)
3x - 9y = 33 -------------(ii)
multiply equation (i) by 3
(i)* 3 12x + 9y = -3
(ii) <u> 3x - 9y = 33</u>
add, 15x = 30
x = 30/15
x = 2
Put x =2 in Equation (i)
4*2 + 3y = -1
8 +3y = -1
3y = -1-8
3y = -9
y = -9/3
y= -3
Answer:
Step-by-step explanation:
11x+6 = 15x-26
This is indeed a linear equation. y-4x=9 in standard form is y=4x+9.
Answer:
<u>∠J = 31.06°</u>
Step-by-step explanation:
Taking the inverse sin function :
- sin ∠J = 1.6/3.1
- J = sin⁻¹ (0.516)
- <u>∠J = 31.06°</u>
