It's a good idea to get into the habit of

using parenthses when substituting

numbers in for variables.

Since x = -4 and y = -2, 5x - y is 5(-4) - (-2).

Now, 5(-4) is -20 and minus a negative 2

can be thought of as plus a positive 2.

So we have (-20) + (+2) which equals -18.

Find the measure of the indicated arc
taurus [48]

Answer:

m(ABC) = 218°

Step-by-step explanation:

The measure of any arc with end points of an inscribed angle = 2 × inscribed angle

Inscribed angle = m<AMC = 109°

Intercepted arc = m(ABC)

Therefore,

m(ABC) = 2 × 109°

m(ABC) = 218°

How can you find the area of a semi-circle
quester [9]

In the case of a circle, the formula for area, A, is A = pi * r^2, where r is the circle's radius. Since we know that a semicircle is half of a circle, we can simply divide that equation by two to calculate the area of a semicircle. So, the formula for the area of a semicircle is A = pi * r^2/2
