Answer:
b) x-intercept
Step-by-step explanation:
First Vilgot made a hat with some amount of yarn, let us assume the weight of yarn used to be 'h', which is fixed. Then we assume the weight of yarn used to make unit length of scarf be 'm'.
The sum of the weight of yarn used to make hat and scarf both is 'x' and the length of scarf is 'y', as given in the question.
The sum of weight of scarf and hat can also be expressed as:
<em>( weight of yarn used to make hat ) + ( weight of yarn used to make unit length of yarn ) × ( length of scarf made )</em>
The above equation in terms of variables (assumed and given) will appear like:
here m and h are constants.
The above equation is represented by the graph given in the question.
So, if in the equation we substitute <em>y=0</em> then <em>x=h</em> which is x-intercept.
Therefore the <u>x- intercept</u> of graph give h which is the weight of yarn used to make hat.
Answer:
D
Step-by-step explanation:
(f×g)(x)=-5x(8x^2-5x-9)=-5x(8x^2)-5x(-5x)-5x (-9)=-40x^3+25x^2+45x
Original amount = new amount/(percentage decrease or percentage increase)
100 - 15 = 85/100 = 75.65 / 0.85 = $89
Hope I'm right and this helps! :)
Answer:
11 cans
Step-by-step explanation:
1 hr = 60 min
33 hrs = ? min
Setup proportion and solve for x:
Do butterfly method and get x = 1980 minutes
Then take the 1980 divide it by 180 to find the number of cans.
