Answer:
m=3*sqrt(2) and n=3
Step-by-step explanation:
tan(45)=3/n
1=3/n, n=3. As it's a right angled triangle, 3^2+3^2=m^2, m=3*sqrt(2)
Answer:
Step-by-step explanation:
<u>Use the slope formula:</u>
- m = (y₂ - y₁)/(x₂ - x₁)
- m = -3, x₁ = 4, y₁ = r, x₂ = 8, y₂ = -11
<u>Substitute values and solve for r:</u>
- -3 = (-11 - r)/(8 - 4)
- -3 = -(11 + r)/4
- 11 + r = 12
- r = 12 - 11
- r = 1
Answer:
One solution: (2.5,0)
Step-by-step explanation:
We can use substitution for the solution. Substitute y=2x-5 to -8x-4y=-20 so that you end up with -8x-8x+20=-20. Next you want to add like terms which will be -16x+20=-20, next you want isolate x by subtracting 20 from both sides and leaves you with -16x=-40. Divide -16 on both sides to fully isolate x and will leave you with x=2.5. Now substiture in 2.5 for x in y=2x-5 to get y=2(2.5)-5 which will then lead to y=0.
