Just solve for x and then compare
We can use substitution or elimination
Let’s use substitution
Make slope intercept equation for the first equation
Y = -x + 5
Now plug in the y value for the second equation
-5x - 4(-x + 5) = -18
-5x + 4x - 20 = -18
-1x = 2, x = -2
There is one solution
Answer: The complete question is "A circle has a radius of \blue{3}3start color #6495ed, 3, end color #6495ed. An arc in this circle has a central angle of 20^\circ20 ∘ 20, degrees. What is the length of the arc?"
The length of the arc is 1.06667 units.
Step-by-step explanation:
According to the question the radius of the circle
and central angle of arc is 
As we know that the length of the arc is given as: 
Where R is radius of the circle, L is the length of the arc and
is central angle in radian.
Now, 
Therefore, length of the arc is

Answer:
96 millimeters
Step-by-step explanation:
If you get 2 per month then by 1 year you have 24 (2*12 since there are 12 months in a year). From there multiply by 4 since you are looking for 4 years (24*4)
