The rotation is 90° counter clockwise.
<u>Step-by-step explanation:</u>
Triangle GHJ has the points G(2,5), H(3,3) and J(1,4)
And the coordinates changes after 90° counterclockwise rotation,
the points are changed from (x,y) to (-y, x) ,
so the triangle G'H'J' has the points G'(-5,2), H'(-3,3), J'(-4,1).
X=2m-nx-4
If you need help just ask me.
For part B
the fixed cost is 500 dollars because it is a set inital amount, the varibale cost is .15 because it is the cost dependent on something else (per indicated variable part)
y=.15x+500
.15 cents per flyer, add 500 because that is the set amount it costs to even create the flyer
Plug in 500 for the equation
y=.15(500)+500
y=75+500
y=575
for part a
b=ka for direct variations so the direct one is C - two items directly multiplied
y=mx+b for partial variation so its A,D - basically the equation of a line
A is neither - shows neither of these relationships
X would have to equal 10. This would be the answer because the numbers have to be proportional. To do that all you have to do is do 12/8. Then you get 1.5. Then you do the same for 15. Do 15/1.5 and get 10.
Yonna, this is the solution to the problem:
Side 1 of the tablet = (4x + 3) cm
Side 2 of the tablet = (-4x² - 2x - 3) cm
Area of the tablet = Side 1 * Side 2
Area of the tablet = (4x + 3) * (-4x² - 2x - 3) cm²
Area of the tablet = (4x * -4x²) + (4x * -2x) + (4x * -3) + (3 * -4x²) + (3 * -2x) + (3 * -3)
Area of the tablet = -16x³ - 8x² - 12x - 12x² - 6x - 9 cm²
Area of the tablet = -16x³ - 20x² - 18x - 9 cm²
