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
Y=-3x+5
Since the slope is -3, you write -3x since x labels the slope. The point is on the y axis giving us the y intercept which is 5.
I don't agree because a pyramid's lateral face is a triangle, and he can only draw a prism if it's rectangular
Answer:
A number that has a greater absolute value then -10 is -15
Step-by-step explanation:
the absolute value basically means to make the negative number a positive.
c + 2c = 33
3c=33 (now divide by 3 both sides of equation)
c=11
so Ann has 11 apples (c=11) and her brother has 22 apples (2c=2×11=22)
