Answer:

B = 80

Step-by-step explanation:

y = 4x

y = 1/2x + 280

Substitute one equation into another.

4x = 1/2x + 280

Combine like terms

3.5x = 280

x = 80

Find an equation in slope-intercept form for the line with a zero slope and passes through (12, -9).

Virty [35]

If the slope is 0, then x does not change at all.

take the given y coordinate, and make that the equation.

so y=-9, since the line will never change.

Help i need the answer idk what or how to do this

14^(7x) = 17^(-8-x)

Take the log of both sides:

7x*log 14 = -(8+x)*log 17, or 7x^log 14 = -8*log 17 - x*log 17.

Grouping the x terms, we get x(7*log 14 + log 17)= -8*log 17

Then:
-8*log 17
x= -------------------------- (answer)
7*log 14 + log 17
