The answer is -2.
im sorry if the work is messy.
Hello! For this question, we are looking for the percent of change. The formula for percent of change is change/original = x/100, where change is tge difference between two numbers, and the original is the previous number. 136,500 - 130,000 is 6,500. The original number is 130,000. It would be set up like this:
6,500/130,000 = x/100
Let's cross multiply the values. 6,500 * 100 is 650,000. 130,000 * x is 130,000x. That makes 650,000 = 130,000x. Now, divide each side by 130,000 to isolate the x. 130,000x/130,000 cancels out. 650,000/130,000 is 5. There. x = 5% increase. The answer is A: 5%.
Answer:
y = x -3
Step-by-step explanation:
From the graph we see the line goes from point (0, -3) to point ( 3, 0), so we can find the slope as m= rise ( go up 3) / run ( go to the right 3) = 3/ 3 = 1
From the graph we can also see the y-intercept ( where the line intersects the y axis is at b = -3
The general equation of the line is y= mx+ b
Our line's equation is y = x -3, because m=1 and b= -3
Answer:
x = 2
Step-by-step explanation:
The sum of the 3 angles in the triangle = 180°
Sum the 3 angles and equate to 180
6x + 15 + 90 + 63 = 180
6x + 168 = 180 ( subtract 168 from both sides )
6x = 12 ( divide both sides by 6 )
x = 2
Answer:
y2 = m(x2 - x1) + y1
Step-by-step explanation:
Given the slope formula :
m = (y2 - y1) / (x2 - x1)
To obtain an equivalent expression :
We cross multiply :
m(x2 - x1) = y2 - y1
Making y2 the subject ;
Add y1 to both sides
m(x2 - x1) + y1 = y2 - y1 + y1
m(x2 - x1) + y1 = y2
y2 = m(x2 - x1) + y1
