Answer:
x=30
Step-by-step explanation:
The two angles are supplementary. They add to 180
4x+20 + 40 =180
Combine like terms
4x+60 =180
Subtract 60 from each side
4x+60-60 = 180-60
4x = 120
Divide each side by 4
4x/4 = 120/4
x = 30
If f(x) = 2x -6+4
Then
f(-2) = 2(-2) -2
f(-2) = -6
If you think about what times what equals 93.
Type in the calculator square root of 93, and you get 9.643650761... but you want to round this decimal to the nearest tenth or hundredth... so 9.64
Start with y = x^2.
Vertical reflection over the x-axis: y = -x^2
Vertical translation up by 2: y = x^2 + 2
Horiz. transl. left by 5: y=(x+5)^2
Answer:
4x^3 -x^2 -6x +10
Step-by-step explanation:
You can perform the division of (4x^4 +11x^3 -9x^2 -8x +30)/(x +3) by polynomial long division or by synthetic division. The latter is shown below.
The result of the division is ...
4x^3 -x^2 -6x +10
