The slope of 2x - y = 9 is 2x
Answer:
blue
Step-by-step explanation:
70 = 2m so m=35
360 - 70 - 70 = 220
220/2 = 110 = n
None 3 * 66 = 198
ALL triangles have a total degree measure of 180 degrees
Answer:
Step-by-step explanation:
1. Y varies jointly as R and T
Y = k*R*T
Y = kRT
Where,
k = constant of proportionality
2. B is directly proportional to the square of A and inversely proportional to the cube of C.
B = k(A²) / C³
B = kA²/C³
Where,
k = constant of proportionality
y = 8 -2x
x + 2 (8 - 2x) = 1
x + 16 - 4x = 1
x - 4x = -15
-3x = -15
x = 5
If x = 5, then we can substitute in...
5 + 2y = 1
2y = -4
y = -2
Now let us check that by substituting those values in to the equation
2x + y = 8
2 (5) + (-2) = 8
That is correct so we have the right values for x and y/
