Use the distributive property to evaluate 4(2x - 1) when x = 5
Answers
The value of the expression, when the value of x equal to 5, will be 36.
What is Algebra?
The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
The expression is given as,
⇒ 4(2x – 1)
On applying distributive property, we have
⇒ 8x – 4
Then the value of the expression when the value of x equal to 5, will be
⇒ 8 x 5 – 4
⇒ 40 – 4
⇒ 36

Answer:
36
Step-by-step explanation:
4(2(5) -1)
4(10-1)
40-4
=36
OR
**You can subtract 10 and 1 first instead of distributing 4 into each number. Either way, you still get 36**

y=5x-4 is the equation of the line 3y = 15x - 12 in slope intercept form.
What is Slope of Line?
The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
The given equation is 3y = 15x - 12
Three times of y equal to fifteen times of x minus twelve.
We need to convert it to slope intercept form y=mx+b to do this we have to isolate the y term and divide the equation coefficient by 3
Divide both sides by 3
y=15/3x-12/3
When fifteen is divided by three the result is five and when twelve is divided by three we get four.
y=5x-4
Hence, y=5x-4 is the equation of the line 3y = 15x - 12 in slope intercept form.
