Answer:
x =
Step-by-step explanation:
Given
Ax + By = C ( isolate the term in x by subtracting By from both sides )
Ax = C - By ( divide both sides by A )
x =
Answer:
Step-by-step explanation:
Solve Ax+By=C for x.:
Ax= - By+C
case 1 : A≠0 x = (- B/A)y+C/A
case 2 : A=0
you have : 0x = - By+C
B=0 : ox = C C = 0 infinity of x C≠0 no solutions
Answer:
7.6 ft² ( to 1 dec. place )
Step-by-step explanation:
given 2 sides of a triangle and the angle between them, the area (A) is calculated using the formula
A = ac sin B
= 0.5 × 4 × 13 × sin 17° ≈ 7.6
Answer:
The period of Y increases by a factor of with respect to the period of X
Step-by-step explanation:
The equation shows the relationship between the orbital period of a planet, T, and the average distance from the planet to the sun, A, in astronomical units, AU. If planet Y is k times the average distance from the sun as planet X, at what factor does the orbital period increase?
For the planet Y:
For planet X:
To know the factor of aumeto we compared with
We know that the distance "a" from planet Y is k times larger than the distance from planet X to the sun. So:
Finally the period of Y increases by a factor of with respect to the period of X
