He would have $4131 left from $5400 with a decrease with 23.5%
Answer:
y = (2/3)x + 9
Step-by-step explanation:
Equation of a straight line is y = mx + b. You are trying to finish the equation.
Note that:
m = slope = 2/3
b = y-intercept = 9
Plug in the corresponding numbers to the corresponding variables:
y = mx + b --> y = (2/3)x + 9
y = (2/3)x + 9 is your equation.

7.79cm It is an equilateral triangle so it has 3 equal sides. That means each side is 9cm. <span>
Now draw a line from the top of the equilateral triangle to the base, and dividing it into two. You will have made two smaller triangles, with sides 9, 4.5, and h (the one you want to find).
A line drawn from the apex of an equilateral triangle to the midpoint of the base is perpendicular to the base, so you can use Pythagoras' Theorem!
4.5^2 + h^2 = 9^2
h = sqrt(9^2 - 4.5^2)
Therefore, the height is 7.79cm (2 decimal places)</span><span>

Answer:
A.3
Step-by-step explanation:
Since the lines are parallel that angle is 90 same as the other. So you plug in all your answers to see with one gives you 90 that being 3 because 30(3)=90.
