F(x)=x²+3x ; [-2;3]⇒Δf/Δx=(f(3)-f(-2))/(3-(-2))=4 (A)
f(x)=3x-8 ; [4;5]⇒Δf/Δx=<span>(f(5)-f(4))/(5-4)=3 (B)
f(x)=x</span>²-2x ;[-3; 4]⇒<span>Δf/Δx=(f(4)-f(-3))/(4-(-3))= -1 (C)
f(x)=x</span>²-5 ;[-1; 1]⇒<span>Δf/Δx=(f(1)-f(-1))/(1-(-1))= 0 (D)

40% of 60 is 24
To convert from percent to decimal, divide the percent without the percent symbol by 100.
so, 40% = 40/100 = 0.4
40% 60 is just 0.4*60 = 24
The correct answer for this would be X=10
Answer:
put your first point at 7 in y axis that point go down 3 to the rights side 1 and your point should be at (1,4) then connect the dots and that's how you graph it
Step-by-step explanation:
-------------------------------------------
Define x:
-------------------------------------------
Let the shorter piece be x.
Shorter piece = x
Longer piece = 6x
-------------------------------------------
Construct equation:
-------------------------------------------
x +6x =35
7x = 35
x =5
-------------------------------------------
Find the length:
-------------------------------------------
Shorter length = x = 5 feet
Larger length = 6x = 6(5) = 30 feet
-------------------------------------------
Answer: The shorter piece is 5 feet.
-------------------------------------------
