Answer:

Step-by-step explanation:
You are looking for the point of intersection of these two functions.
Substitution:
- This are now your formulas

- You are going to substitute x, so you can solve for y




- Now you are going to substitute y to find x



- Now lets check if it is correct

So it is true, making (-4 , -5) your point of intersection.
hope it helps

Step-by-step explanation:
The sum of the angles of a triangle is 180
26x+6 + 21x-1 +11x+1 = 180
Combine like terms
58x +6 = 180
Subtract 6 from each side
58x = 180-6
58x = 174
Divide by 58
58x/58 =174/58
x=3
We want <C
<C = 11x+1 = 11*3+1 = 33+1 = 34

Step-by-step explanation:
Equation for Fast Internet is
45 + 50.45x
Equation for Quick Internet is
57.95x
To find when they cost the same , equate the 2 equations
45 + 50.45x = 57.95x ← required equation
Solve the equation by subtracting 50.45x from both sides
45 = 7.5x ( divide both sides by 7.5 )
6 = x
Both services would cost the same after 6 months
