3y=8x

Explanation:

If y varies directly with x then

y=c⋅x for some constant of variation c

If (x,y)=(14,23) is a solution to this equation, then

23=c⋅14

→c=23⋅41=83

y=83x

or (clearing the fraction)

3y=8x

Solve the equation: 5x + 5 = 0

Igoryamba

Answer:

x = -1

Step-by-step explanation:

5x + 5 = 0

Subtract 5 from each side

5x+5-5 = 0-5

5x = -5

Divide by 5 on each side

5x/5 = -5/5

x = -1

Parallel to y - 2x = 4 and passes through (0,5)

wolverine [178]

Answer:

y=2x+5

Step-by-step explanation:

y=2x+4 means that the slope is m1=2

A parallel line shall have the same slope so

m2=m1=2

Therefore, the equation of the new line will be

y=2x+q

where q is the y-intercept, that is 5 because the line must pass in (0,5), so

q=5

and

y=2x+5

Need some help, ASAP if possible. TY in advance!

ValentinkaMS [17]

Answer:

B $(f-g) (x)= \sqrt{\frac{x} {8} } -\frac{2}{x} +6$

Step-by-step explanation:

$f(x)= \sqrt{\frac{x} {8} } +11$ ------------------(1)

$g(x)=5+\frac{2}{x}$ -----------------------(2)

Subtracting eq (2) from eq (1)

$f-g= \sqrt{\frac{x} {8} } +11 - (5+\frac{2}{x} )$

$f-g= \sqrt{\frac{x} {8} } +11 - 5 -\frac{2}{x}$

$f-g= \sqrt{\frac{x} {8} } -\frac{2}{x} +6$
