Area of figure is the total number of 1 square unit in the figure. For a rectangle, it is calculated from the product of its length and its width. For this case, we are given:
Width = x
Length = 7x
Area = x(7x) = 7x^2
The coefficient 7 would mean that the length is 7 times longer than the width, x.
Answer:
y = -2x - 9
Step-by-step explanation:
so we have our two points, (-4,-1) and (-8,7) What we need to do to find our slope is y2 - y1 over x2 - x1. Once plugging in the numbers and subtracting it should give you 8/-4. 8 divided by -4 is -2. m = -2. Now to find our "b" we plug in our slope, and plug in one of the two points into the format of y = mx + b.
-1 = -2(-4) + b
multiply -2 and -4
-1 = 8 + b
we subtract 8 from itself and -1
-9 = b
Our equation is y = -2x - 9
Answer:
Answer: The truck is worth of $27508 after 2 years.
Step-by-step explanation:
Since we have given that
The value in dollars v(x), of a certain truck after x years is represented by the equation :
We need to find the price of the truck after 2 years,
so, x= 2
So, we put the value of x = 2 in the above equation:
Hence, the truck is worth of $27508 after 2 years.
C. 33.60
that would be because 25% of 56 is 14 so 56-14=42
and 20% of 42 is 8.40
so 42-8.4= 33.60
$33.60 is your answer
