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
First one is 672 the second one is 1008 the third one is 1344 the last one is 1512
Answer:
gallons = dependent
minutes = independent
Step-by-step explanation:
independent variable = the variable being manipulated/changed
dependent variable = the variable being changed as a result
gallons = dependent (of the minutes of running water)
minutes = independent (affecting the gallons)
Step-by-step explanation:
7x+22=2(5x+2)
7x+22=10x+4 (-7x)
3x+4=22 (-4)
3X=18 (divide by 3)
X=6 pencils
check if the number is correct
asha= 7*6=42 42+22 is 64
Lucy= 5*6=30 30+2 is 3264/32 is 2
asha= 7*6=42 42+22 is 64Lucy= 5*6=30 30+2 is 3264/32 is 2there fore asha sells twice as many as Lucy
Answer:7
Step-by-step explanation:
1/2 of j is the same as j ÷ 2
14 ÷ 2 = 7
