Answer: A. 30
Step-by-step explanation:
We will plug the value of x, 15, into the given expression. Then, we will use the order of operations, also known as PEMDAS. View attached if you need a review.
5² + (x / 3)
5² + (15 / 3)
25 + (5)

A. 30
4x^6 / (2x - 6)
4x^6 / 2(x - 3)
2x^6 / (x - 3)
Answer:
y = x + 8
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
rearrange 5x - 2y = 8 into this form
subtract 5x from both sides
- 2y = - 5x + 8 ( divide all terms by - 2 )
y = x - 4 ← in slope-intercept form
with m =
• Parallel lines have equal slopes, hence
y = x + c ← is the partial equation
to find c substitute (- 2, 3) into the partial equation
3 = - 5 + c ⇒ c = 3 + 5 = 8
y = x + 8 ← equation of parallel line
Answer:
x = 1
y = 0
Step-by-step explanation:
You did a great job solving one of the equations for a single variable. You solved for x. But what your paper shows is that...it jind of looks like you were going to substitute the 2y+1 into y. BUT you need to substitute it into x.
-4x + 3y = -4
x = 2y + 1
Fill in 2y + 1 into x in the first equation.
-4(2y+1) + 3y = -4
Now you have an equation in one variable. There are only y's in this equation. Next, distribute.
-8y - 4 + 3y = -4
combine like terms.
-5y - 4 = -4
add 4 to both sides.
-5y = 0
divide by -5
y = 0
It's okay that it cam out to be zero. Its fine!
y=0
Put it back in one of the original equations to find x.
x = 2y + 1
x = 2(0) + 1
x = 1
The solution is
x=1
y=0
You can write this as an ordered pair.
