M of angle FCE + 63 =180 (give that they are supplementary)
180-63=FCE
117=m of angle FCE

Line BCE is supplementary, which means its straight or it is 180 degrees. so you take the angle of BCF, which is 63, and subtract that from 180 to get 117, so the measure of angle FCE is 117 degrees

Answer:

see below

Step-by-step explanation:

It is easiest to compare the equations when they are written in the same form.

The first set can be written in slope-intercept form.

y = 2x +7

y = 2x +7 . . . . add 2x

These equations are identical, so have infinitely many solutions.

The second set can be written in standard form.

y +4x = -5

y +4x = -10

These equations differ only in their constant, so have no solutions.

The third set is already written in slope-intercept form. The equations have different slopes, so have exactly one solution.

Answer:

Step-by-step explanation:

All the sides are complete, hence we can use the information given to find just 1 triangle

Triangles

From the given information, we have that:

m<B = pi/6 = 30 degres

c = 10

b = 5

This shows that we can use the cosine rule to find the third side b of the triangle. Since all the sides are complete, hence we can use the information given to find just 1 triangle

Given : Fix amount charges = $200.

Each month additional charge = $50.

Let us assume number of months are taken by x.

So, we can setup a function as

Total charge = Fix charge + each month charge * number of months.

f(x) = 200 + 50*x

Or f(x) = 200 +5x.

Where function f is the total charge of x number of months.

The values of x's represents domain and function value represents range.

According to problem, it is said " first three months".

So, we need to take number of months as x=0,1,2,3.

And we need to find values of function for those x values.

On plugging x=0,1,2 and 3 we would get

f(0) = 200 +5(0) = 200 +0 = 200.

f(1) = 200 +5(1) = 200 +50 = 250.

f(2) = 200 +5(2) = 200 +100 = 300.

f(3) = 200 +5(3) = 200 +150 = 350.

We got function values 200,250,300 and 350.

Therefore, with respect to the given situation, the domain of the funtion is

{0,1,2,3} and Range { 200,250,300, 350}.
