Answer:
Answer is below
Step-by-step explanation:
Charles is wrong because 3 doesn't represent exponential decay. This is because 3 is greater than 1, so it represents exponential growth. If the number was less than 1, then it would represent exponential decay.

Work on Both sides of the equation by doing the same thing on both sides. This will get your answer.
Answer:
x=−1 and y=3 or (-1,3)
WORK:
Let's solve your system by substitution.
y=2x+5;y=−3x
Step: Solve y=2x+5 for y:
y=2x+5
Step: Substitute 2x+5 for y in y=−3x:
y=−3x
2x+5=−3x
2x+5+3x=−3x+3x (Add 3x to both sides)
5x+5=0
5x+5+−5=0+−5(Add -5 to both sides)
5x ÷ 5 = -5÷5 (divide both sides with 5)
x=−1
Step: Substitute −1 for x in y=2x+5:
y=2x+5
y=(2)(−1)+5
y=3(Simplify both sides of the equation)
Answer:
x=−1 and y=3
(Incase you needed to show your work)
Hope this helps :)
No. 1/12 is a smaller amount than 1/3.
Lets assign some variables: Let
y = Darren + Michael
x = Brian.
Given:
y = 2x + 30 (Darren and Michael [y] earn [=] 30 more than[+30] twice what Brian earns[2x])
y = 3800 (Darren and Michael [y] earn [=] $3800)
Solve for x: What Brian earns.
I will solve this by substitution. Plugging in 3800 for y:
3800 = 2x + 30 subtract 30 from both sides
3770 = 2x divide by 2 on both sides
1885 = x flip the equation
x = 1885
Brian earns $1885 per month.
