This is what the graph system would look like
First, take off 4 feet of Stacy's rope, which is 19. (23-4=19). Then, divide 19 by 3. It should equal 6.3...
Answer: 121 seats
Step-by-step explanation:
11/15 of the seat taken out of 165 so
11/15× 165= 120.9999≈121 seats
X^2 - 5x - 7 = 0
x = (-b (+-) b^2 - 4ac) / 2a
a = 1, b = -5, c = -7
x = (-(-5) (+-) sqrt (-5^2) -4(1)(-7)) / 2(1)
x = (5 (+-) sqrt 25 + 28) / 2
x = (5 (+-) sqrt 53) / 2
Answer:
C(w) = 6w + 9
Step-by-step explanation:
Anytime 0 is given somewhere, it should be given close scrutiny. In an equation whose general form is
y = mx + b
0 will determine the y intercept immediately.
So when x = 0, y will equal
y = 0*m + 9
So b = 9
y = mx + 9 Now we need to find m
I should start using your variables.
C(w) = m*w + 9
when w = 3 then C(3) = 27
27= 3m +9
27-9 =3m + 9 -9
18 = 3m
18/3 = 3m/3
x = 6
So the complete equation is
C(w) = 6w + 9
