Solve for x: 2(10-2x) = 4(3x + 1). Write your answer as a fraction.

qwelly [4]

Answer:

$\boxed{x=1}$

Step-by-step explanation:

$2(10-2x) = 4(3x + 1)$

$\sf Expand \ brackets.$

$20 - 4x = 12x + 4$

$\sf Subtract \ 12x \ and \ 20 \ from \ both \ sides.$

$20 - 4x - 12x - 20 = 12x + 4 - 12x - 20$

$-16x = -16$

$\sf Divide \ both \ sides \ by \ -16.$

$\displaystyle \frac{-16x}{-16} =\frac{-16}{-16}$

$x=1$

Y = 5-3x, Darw the graph of the function. Use the find the value of y when x=4, and when x = 5

stellarik [79]

Answer:

The line passes through (4, -7) and (5, -10).

Step-by-step explanation:

When x = 4, y = 5 - 3(4), or 5 - 12, or -7. Thus the point (4, -7) lies on the graph. Similarly y = 5 - 3(5) = -10 when x = 5. Thus, the line also goes through (5, -10). Plot these two points and draw a line through them. Doing this will result in the desired graph.
