Answer:
x=3
Step-by-step explanation:
Sub y=x-1 into 2x+y=8.
You will get 2x+x-1=8.
Simplify 3x-1=8
Solve 3x=9
x=3
Answer:
Direct proportional
Step-by-step explanation:
The direct proportional refers to the effect of one element to the other element.
In other words, when one variable is increased the other variable is also increased but the product would remain the same
y = kx
This equation represents that y is directly proportional to x
As in the given case, the bonus amount is of $10,000 and the amount earned by every employee depends on how numbers of workers are earning a bonus.
Plus, the equation is
y = 10,000
This shows the direct proportional example
Answer: x=3
Step by Step:
(x+2)2+(y-3)2=4
2x+4+(0-3)x2=4
2x+4-3x2=4
2x+4-6=0
2x=6
x=3
First divide both sides by 2 so that we can get rid of the parentheses, so we get
now subtract 5 from both sides
then finally we want x alone so we'll divide both sides by 3 and get our final answer!
