Answer :
Letter C : e = 40,000 + 200 x c
answer:
C. 16
explanation:
when x is 0, the y-intercept is 8
coordinates: (0,8) and (4,6)
slope:
equation:
[ where m is slope and b is y-intercept ]
solve for x-intercept:
note: zeros of a function are the values of x when f(x) is equal to 0
Answer:
x = 1.5
y = 3
Step-by-step explanation:
to solve this system of equation using the substitution methods we say let
2x+3y=12................................... equation 1
y=x+1.5..................................... equation 2
substitute equation 2 into equation 1
2x+3y=12................................... equation 1
2x + 3( x + 1.5) = 12
2x + 3x + 4.5 = 12
5x + 4.5 = 12
collect the like terms
5x = 12 - 4.5
5x = 7.5
divide both sides by the coefficient of x which is 5
5x/5 = 7.5/5
x = 1.5
put x = 1.5 into equation 2
y=x+1.5..................................... equation 2
y = 1.5 + 1.5
y = 3
therefore the value of x = 1.5 and y = 3 respectively.
Answer:
B = (C-Ax)/y
Step-by-step explanation:
Solve for B.
Ax+By=C
making B the subject of formula '
Ax+By=C
subtract Ax from both sides
By = C-Ax
By = C-Ax
divide both sides by y
B = (C-Ax)/y
