The answer is
a) one solution (0,-1)
just substitute y
we are told that y = 5x-1
so do
-15x — 3 (5x-1) = 3
and solve from there
M = 9
o = 7
m + 0 = 9 + 7 = 16
Hence, the answer is 16.
Circumference of a circle = 2π r (2 * π * radius) or πd (π * diameter)
The mean is 52 inches.
49, 50, 51, 52, 53, 54, 55 add the numbers all together then divide 364 by 7 = 52
you do not include the outier
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>
