Answer:
y = -5x + 90
Step-by-step explanation:
y = mx + b is slope intercept form
b is the y intercept, meaning that 90 is the y-intercept
m is the slope (rise over run), 20/4, 5/1, 5
y = -5x + 90
this wasnt the best explanation but I hope it helped
Okay. Mainly for these questions, we have to write out equations.
1. For the vacation days given in the U.S., that equation would be 25-n, because the U.S. gets fewer days than the Japanese worker does.
Equation: 25-n
2. The equation for this one would be 26s, because there are 26 grams of protein for each cup of cottage cheese. To find out the total amount of protein for all of the cups together, that equation works work out.
Equation: 26s
<span>To write this sum as a single fraction we need to put both of them over a common denominator. Our common denominator will be the simplest thing that has both 3 and 5 as a factor, which is 15 (x-2)/3 + (x+3)/5 = 5(x-2)/15 + 3(x+3)/15 Now we can put both numerators over the same denominator to get (5(x-2) + 3(x+3))/15 Next we should multiply out and simplify the numerator (5(x-2) + 3(x+3))/15 = (5x -10 +3x +9)/15 = (8x-1)/15
hope this helps but dont know if its right</span>
Given:
The figure of triangle ABC.
The area of the triangle ABC is D.
To find:
The value of m and n in the given expression.
Solution:
Let h be the height of the triangle ABC.
Area of a triangle is:
Where, b is the base and h is the height of the triangle.
The area of the triangle ABC is D.
...(i)
In a right angle triangle,
[Using (i)]
...(ii)
We have,
...(iii)
On comparing (ii) and (iii), we get
Therefore, the required values are .
I believe the answer is 540 students. Hope this helped! ;)
