Step-by-step explanation:
First we solve it.
I'll use substitution.
In the first equation y equals -2x+2 so we can apply that to the second equation
2y + 4x = 4
2(-2x+2) + 4x = 4
distribute
-4x+4+4x=4
simplify
4=4
To figure out how many solutions it has:
•If both side of the equal sign are exactly the same: Infinitely many
ex: 6x=6x
•If both sides of the equal sign do not match when completely simplified: No solutions
ex: 3x=-5x
•If it creates an equation: 1 solution
ex: x=3+2y
Since both sides of the equal sign are 4, we have infinitely many solutions.
Hope this helps! If you have any questions on how I got my answer feel free to ask. Stay safe!
Answer:
2 gallons
since each pitcher holds 2 quarts of water and 4 quarts= 1 gallon, Desta poured 2 gallons of water into her cooler
Answer: smaller angle = 17°
The angle is a right angle so the total degree of the angle would be 90°
Step-by-step:
Equation:
(4x+1)+(x-1) = 90
5x = 90
X = 18
Smaller angle:
(X-1)
(18-1)
17°
Answer:
a(46) = -1.5 + 0.2(45) = -1.5 + 9 = 7.5
Step-by-step explanation:
Each term of this sequence is 0.2 greater than the previous term. The formula for this arithmetic sequence is
a(n) = -1.5 + 0.2(n - 1)
and so the 46th term is:
a(46) = -1.5 + 0.2(45) = -1.5 + 9 = 7.5
