You would need 31 Vans for everyone to be transported.
ANSWER
(–4.5, 4.25)
EXPLANATION
The first equation is
This function is in the slope-intercept form
The second equation is:
x + 2y = 4
2y =-x+ 4
The graph of the two functions are shown in the attachment.
The point of intersection represents the solution to the system of equations they represent.
The solution is
(–4.5, 4.25)
Answer:
1.) -7/2
2. -42/5
hope this helps, I just did the math.
Answer:
(x - 12)(x² - 2)
Step-by-step explanation:
Given
x³ - 12x² - 2x + 24 ( factor the first/second and third/fourth terms )
= x²(x - 12) - 2(x - 12) ← factor out (x - 12) from each term
= (x - 12)(x² - 2)
1. first parabola is up, so a are going to be positive
y = a(x-r)(x-s),
roots -7,-3, so we can write y=a(x+7)(x+3) [1]
we can take point (-5,-2), substitute into equation [1], and find value of a
-2=a(-5+7)(-5+3)
-2=a*2*(-2)
a=1/2
so first parabola has an equation
y=1/2(x+7)(x+3)
2. second parabola
y=a(x-r)(x-s) roots are 2 and 4 so we ca write
y=a(x-2)(x-4) take point (3,4) and substitute into this equation
4 =a(3-2)(3-4)
4=-a
a=-4, and it will look down
y=-4(x-2)(x-4)
