Answer:
x=40
Step-by-step explanation:
subtract first then multiply
7*38=7x-14
move terms 266=7x-14
calculate-7x=-14-266
divide both sides by -7 (-7x=-280)
solution x=40
Those are all lines...
So the x interval is from -2 to 3, because of x=-2 and x=3
The upper line is y(u)=4x and the lower line is y(l)=x-5
So the area between the two lines is:
A=⌠y(u)-y(l) dx
A=⌠4x-x+5 dx
A=⌠3x+5 dx
A=[3x^2/2+5x]
A=[(3x^2+10x)/2], x=[-2,3]
A=(1/2)(27+30-(12-20))
A=(1/2)(57+8)
A=(1/2)(65)
A=32.5 u^2

Answer : 2.5
Step - by - step explanation :
X / Y = COP
5 / 2 = 2.5 or 2 1/2
Y = 2.5x
