Answer:
Area = 5/6 * x^2
Step-by-step explanation:
If you are given the base and height of a certain triangle, you will most likely be asked to find the area
The area of any triangle can be found by
Area = base*height * (1/2)
In your case
Area = (5/3)*x*x* (1/2) = 5/6 * x^2
In your case, x should be a known parameter of your triangle, so if you have the value of the height, you should be able to find the area. Or conversely, if you have the area, you can find the length and height of your triangle.
Answer:
Step-by-step explanation:
Sum of 1 through 100 = 100×(1+100)/2
8a+12b because you multiply 2 by each number. For example 4a times 2 is 8a and 6b times 2 is 12b
Hope that helped :)
Answer:
The equation would be y = -1/5x + 5
Step-by-step explanation:
To find the equation of this new line, we first need to identify the slope of the first line. We do this by putting it into slope intercept form.
x + 5y = 10
5y = -x + 10
y = -1/5x + 2
In slope-intercept form, the slope is always the coefficient of x. This makes the slope of the first equation -1/5. Since parallel lines have the same slope, our new slope will also be -1/5.
Given that and the point, we can solve for the equation using point-slope form.
y - y1 = m(x - x1)
y - 6 = -1/5(x + 5)
y - 6 = -1/5x - 1
y = -1/5x + 5
The last one will give the incorrect slope
