11)x+y=-2. 12)y=2x+1
2x-y=5. 2y=x +17
————— —————
y=1/3x+3 3y=3x÷3+18÷3
y=1x+6
if you have a problem similar to these that I did for you you just add the x variables and the y variables (if the y variable has any ) and divide the y variable with the 1st and 2nd variable
and you get the y=mx+b equation if you need the x variable too you multiply the y variable answer with the number beside it
Answer:
a=12
b=9
Step-by-step explanation:
3/4 of 12 is 9 and 9 plus 12 is 21
6 fluid ounces is more than 10 tablespoons
Answer:
Step-by-step explanation:
Number of vertices
3
Variable constraints
a>0 and b>0
Diagonal lengths
(data not available)
Height
b
Area
A = (a b)/2
Centroid
x^_ = (a/3, b/3)
Mechanical properties:
Area moment of inertia about the x-axis
J_x invisible comma x = (a b^3)/12
Area moment of inertia about the y-axis
J_y invisible comma y = (a^3 b)/12
Polar moment of inertia
J_zz = 1/12 a b (a^2 + b^2)
Product moment of inertia
J_x invisible comma y = -1/24 a^2 b^2
Radii of gyration about coordinate axes
r_x = b/sqrt(6)
r_y = a/sqrt(6)
Distance properties:
Side lengths
a | sqrt(a^2 + b^2) | b
Hypotenuse
sqrt(a^2 + b^2)
Perimeter
p = sqrt(a^2 + b^2) + a + b
Inradius
r = 1/2 (-sqrt(a^2 + b^2) + a + b)
Circumradius
R = 1/2 sqrt(a^2 + b^2)
Generalized diameter
sqrt(a^2 + b^2)
Convexity coefficient
χ = 1
Mean triangle area
A^_ = (a b)/24
