Answer:
50
Or D (if D is 50)
Step-by-step explanation:
4.5x+396=621
Subtract 396 from both sides. (Subtraction Property of Equality)
4.5x=225
Divide both sides by 4.5 to get x by itself. (Division Property of Equality)
x=50
Answer:
m = 1
Step-by-step explanation:
slope = (y₂-y₁)/(x₂-x₁)
m = (4 - -1) / 1 - -4) = 5/5 = 1
Sinx =8/40
in order to solve this you would have to use the inverse which would be Sin^-1(8/40) giving you 11.5
Answer:
see explanation
Step-by-step explanation:
Given
y = 3(x - 3)(x - 2)
To find the x- intercepts, let y = 0, that is
3(x - 3)(x - 2) = 0
Equate each factor to zero and solve for x
x - 3 = 0 ⇒ x = 3
x - 2 = 0 ⇒ x = 2
Thus the x- intercepts are x = 2 and x = 3
To find the y- intercept let x = 0 and equate for y, that is
y = 3(0 - 3)(0 - 2) = 3(- 3)(- 2) = 3 × 6 = 18
Thus the y- intercept is y = 18
Answer:
7
Step-by-step explanation:
39 divided by 5 is 7.8, so he can only fill seven boxes with muffins.
