Answer:
c is the supplement angle
Answer:
$3750 and $4250
Step-by-step explanation:
x + 500 = y
.045x + .035y = 317.50
.045x + .035(x + 500) = 317.50
.045x + .035x + 17.5 = 317.50
.08x = 300.00
x = 3750
y = 4250
Start with the general formula. The key word is difference. So the general formula is
D(x) = W(x) - R(x) Now substitute in the values for W(x) and R(x)
D(x) = 0.002x^3 - 0.01x^2 - (x^2 - 4x + 13) Be very careful about the sign in front of the brackets.
D(x) = 0.002x^3 - 0.01x^2 - x^2 + 4x - 13 Do you see what that minus sign did? It affected all 3 terms.
D(x) = 0.002x^3 - 1.01x^2 + 4x - 13 <em>Note: -0.01 - 1x^2 = - 1.01 x^2</em>
That gives you a clear cut answer
C<<<<< answer.
That sign is the worst part of the question. Make sure you understand what it did.
Answer:
Write 0.72 as
0.72
1
Multiply both numerator and denominator by 10 for every number after the decimal point
0.72 × 100
1 × 100
=
72
100
Reducing the fraction gives
18

When any point say (x,y) is rotated 270 degree counterclockwise then it changes to (y,-x).
So for any image, you can collect given coordinate points
then apply above formula like if given point is (1,3) then it will change to (3,-1) after 270 degree counterclockwise rotation.
