Answer: y= 7,250x + $225,000
Because the graph is linear, you can express it in y = x+a form where y is the price and x is the year. The slope of the graph would be: ($300,000-$225,000)/ 12-0= 7,250
In year 0, the house is price $225,000, then a=$225,000
The graph would be: y= 7,250x + $225,000
You know when a squared number is ration when it is a perfect square like the square root of 25 is 5. The square root can't be a decimal.
Answer:
(4, - 6 )
Step-by-step explanation:
7x - y = 34 ( multiply through by - 1 )
- 7x + y = - 34 ( add 7x to both sides )
y = 7x - 34 → (1)
2x + 3y = - 10 → (2)
substitute y = 7x - 34 into (2)
2x + 3(7x - 34) = - 10
2x + 21x - 102 = - 10
23x - 102 = - 10 ( add 102 to both sides )
23x = 62 ( divide both sides by 23 )
x = 4
substitute x = 4 into (1)
y = 7(4) - 34 = 28 - 34 = - 6
solution is (4, - 6 )
Answer:
Then the solution set is all the values of x equal to or larger than -3.
Step-by-step explanation:
First, we know that each long strip represents an x.
Each white square represents 1.
Each grey square represents -1
Then, at the left side, we have:
8 long stripes.
12 white squares
Then we can write that as:
8*x + 12*1 ≥
And in the right side, we have 12 grey squares, then that is:
≥ 12*-1 = -12
Then the inequality is:
8*x + 12 ≥ -12
To find the solution set, we just need to isolate x.
First, we can subtract 12 in both sides to get:
8*x + 12 - 12 ≥ -12 - 12
8*x ≥ -24
Now we can divide both sides by 8
8*x/8 ≥ -24/8
x ≥ -3
Then the solution set is all the values of x equal to or larger than -3.
