-45x+72
you multiply the 9 by everything in the parentheses
The angle show with the yellow square has a measure of 90°.
Together with angles 1 and 2, they form a straight angle so we have:
∠1+∠2+90°=180°,
subtracting 90° from both sides we have:
∠1+∠2=90°
If the sum of the measures of 2 angles is 90°, the angles are called complementary.
Since the sum of the measures of angles 1 and 2 is 90°, then these 2 angles are complementary.
Answer: <span>They are complementary</span>
point slope form of a line
y-y1 = m(x-x1)
y-7 = -2 (x-1)
if you want it in slope intercept form
y-7 = -2x +2
add 7 to each side
y = -2x +9
Sebastian ran 1.44 miles in the last 24 minutes. First, divide 8.64 by 2.4 to get 3.6 miles per hour. Since the question is asking for the last 24 minutes, divide 3.6 by 60 which gives you 0.06. Then, just multiply the rate per minute by 24 which gives you how many miles he ran in the last 24 minutes of his run.
<h2>
Hello!</h2>
The answer is:
Center: (1,-2)
Radius: 4 units.
<h2>
Why?</h2>
To solve the problem, using the given formula of a circle, we need to find its standard equation form which is equal to:

Where,
"h" and "k"are the coordinates of the center of the circle and "r" is its radius.
So, we need to complete the square for both variable "x" and "y".
The given equation is:

So, solving we have:



Now, we have that:

So,
Center: (1,-2)
Radius: 4 units.
Have a nice day!
