<u>Graph 1</u>
coordinates : (0,-5) (-6,-2)
m = (y2-y1)/(x2-x1)
m = (-2-(-5))/(-6-0)
m = 3/-6 = -1/2
Substitute the values,
y = mx + c
-2 = (-1/2)(-6) + c
-2 = 3 + c
c = -5
Thus, equation is y = -1/2x -5
<u>Graph </u><u>2</u>
coordinates : ( 4,-2) (-5,3)
m = (y2-y1)/(x2-x1)
m = (3-(-2))/(-5-4)
m = 5/-9
Substitute the values,
y = mx + c
-2 = (-5/9)(4) + c
-2 = -20/9 + c
c = 2/9
Thus, the equation is y = -5/9 + (2/9)
Hope it helps :)
Answer choice d (7) would be monomial because it's just one number by itself not attached to anything :)
6.5(2r - s) + 3.7r - 1.25s.....first we distribute the 6.5 thru the parenthesis
13r - 6.5s + 3.7r - 1.25s....now we combine like terms
(13r + 3.7r) = 16.7r
(-6.5s - 1.25s) = -7.75
leaving us with : 16.7r - 7.75s <==
In this item, we are already given that the length of the rectangular book can be represented by the variable x. In this way, the width, which was described to be the difference of the length and 3 inches, can be expressed as x - 3.
The area of the triangle is rectangle is calculated by multiplying the length, x, and the width, which was derived to be x - 3.
Area = Length x width
Area = (x)( x - 3)
Putting in the value of the area, we have the final answer as,
x(x - 3) = 63.8 in²
Hence, the final answer is the first answer.
