Answer:
Slope intercept form is y = mx + b
m is slope
b is y intercept
y = -4/5x + -9

Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
6.2 kilograms/ deciliters
Step-by-step explanation:
megagrams to kilograms
1 megagram = 1000 kilograms
hectoliter to deciliter
1 hectoliter = 1000 deciliter
Using conversion factors
6.2megagrams 1000 kilgrams 1 hectoliter
---------------------- * ----------------------- * -------------------------
hectoliter 1 megagram 1000 deciliters
Canceling like terms
6.2 kilograms/ deciliters
The perimeter of a rectangle is the sum of twice the length and twice the width. When a diagonal is drawn across the rectangle, two congruent triangles are formed. The legs of the triangle are the sides of the rectangle. Right triangles indicates that we can use the Pythagorean theorem. Let length = xLet width = y Set the equation based on what we know. 2x + 2y = 22 x + y = 11 eq1 x2 + y2 = [√65]2 eq2 We have two equations to work with. x + y = 11 eq1 x2 + y2 = 65 eq2 Substitute eq1 into eq2. From eq1, x = 11 - y x2 = (11 - y)2 x2 = (11 - y)(11 - y) x2 = 121 - 22y + y2 (121 - 22y + y2) + y2 = 65 121 - 22y + 2y2 = 65 2y2 - 22y + 56 = 0 2(y2 - 11y + 28) = 0 2(y - 7)(y - 4) = 0 y = 7 and y = 4 Substitute these y values into eq1 to solve for x. x = 11 - 7 and x = 11 - 4 x = 4 and x = 7 Each pair of solutions has the same dimensions. Shorter side = 4Longer side = 7
