Let x = the unknown number to get x = 6
You have to set up a system of equations
x+y=104
3x-y=104
Sodas = 78
Hotdogs = 26
You would round up because 24 16/17 is closer to 25 and 4 8/9 is closer to 5.
which would be 25/5 which estimates to 5.
Answer:
y = 2/3x + 4
Step-by-step explanation:
Slope-intercept form of a line:
- y = mx + b
- where m = slope and b = y-intercept
To find the equation of a line, we need two points that the line passes through.
We can use the x-intercept and y-intercept of the line: (-6,0) and (0,4), respectively.
Find the slope of the line using these two points:
- Slope formula:
Plug the two points into the formula.
Subtract and simplify this fraction.
The slope of this line is m = 2/3.
Now we can look at the graph to determine the y-intercept of this line; the line intersects the y-axis at (0,4) so the constant b = 4.
We can use the slope, m, and the y-intercept, b, and substitute these values into the slope-intercept form of a line.
The equation of the line is y = 2/3x + 4.
Using the Pythagorean theorem
C = sqrt( 9^2 + 40^2)
C = sqrr(81 + 1600)
C = sqrt(1681)
C = 41 cm
