Answer:
1/5
Step-by-step explanation:
In the circle equation shown, the 1/25 all by itself on the right side of the equation is r^2.
r^2 = 1/25
Squareroot both sides.
r = 1/5
(5x - 1)^2 - 25x^2
Rewrite.
(5x - 1)(5x - 1) - 25x^2
FOIL.
25x^2 - 5x - 5x + 1 - 25x^2
Cancel like terms.
-5x - 5x + 1
Combine like terms.
<h3>-10x + 1</h3><h3>The simplified form of the given expression is -10x + 1.</h3>
It looks like you're trying to solve
3x₁ + 7x₂ + s₁ = 49
x₁ +4x₂ +s₂ = 31
Fill in the given values for x₁ and s₁ and your system reduces to
7x₂ = 49
4x₂ +s₂ = 31
The first of these equations tells you x₂ = 49/7 = 7, so the second equation becomes
28 +s₂ = 31
and it is immediately obvious that s₂ = 3
Your solution is (x₁, x₂, s₁, s₂) = (0, 7, 0, 3).
You would start by saying his budget is $80 so you start with 80= he pays an initial fee of $59.50 every month plus $5 per gigabyte so you would set it up like
80=59.50+5x
X being how many gigabytes he uses then you solve 80-59.50 is 20.5 divided by 5 gives you 4.1 but you round down cause you don’t want to pass the limit so therefor the most gigabytes he can use is 4
Answer:
20
Step-by-step explanation:
Segment ST is half and RS is the other half. RT is the whole line so adding ST and RS will get you RT. 4x-7+3x-8=4x. solve for x which will get you 5. Replace the x with 5 in 4x (for segment RT) will get you an answer of 20 for the whole line.
