Answer: ⁻6 is your answer.
Step-by-step explanation:
To find the slope use the slope equation: m=y₁-y₂/x₁-x₂
Sub: m= ⁻8-4/3-1
Solve: m= ⁻12/2
Sam: m= ⁻6/1 or -6
Answer:
Step-by-step explanation:
All you need do is set up a table with three points
x y
2 3- 0.5*2 = 2
0 3
6 0
Now plot the 3 points. You should get something that looks like the graph I downloaded for you.
Let x units be the length of the shortest side of the triangle.
Perimeter of triangle = 2(x + 1) +x = 3x + 2
Perimeter of square = 4(x - 2) = 4x - 8
Equating the two expressions for perimeters, we get:
3x + 2 = 4x - 8
The solution is: x = 10
The answer is 10 units.
Answer:
Step-by-step explanation:
If the new fraction is 8/12 I will show how to find it.
Let's say the original denominator is x, then the numerator is x-4, so we have (x-4)/x.
Then it says f we add 4 to both, so now we have x/(x+4) this equals 8/12. Now, keep in mind -4 cannot be an answer because it would make x/(x+4) be divided by 0 which wouldn't exist.
Now we just use algebra.
x/(x+4) = 8/12
12x = 8(x+4)
12x = 8x + 32
4x = 32
x = 8
So the original fraction (x-4)/x = (8-4)/8 = 4/8
The equation of the line shown is y = 1/3x - 1
Because the slope is rise/run and in this case you rise 1 and run 3. And the y-intercept is -1 because that is where the line crosses the y-axis.
hope this helps :)
