Answer: D) 3x - 5

Step-by-step explanation:

f(x) - g(x)
f(x) = 1/2x - 3
g(x) = -5/2x + 2

Using the values of f(x) and g(x) gives us the equation:
1/2x - 3 - (-5/2x +2)

By distributing the negative sign, the signs on 5/2 and 2 are flipped, making them positive and negative respectively.

Our new equation is:

1/2x -3 + 5/2x -2
Adding up like numbers gives us:

6/2x - 5

Simplifying 6/2x => 3x

So our final equation is:

3x - 5

Find the lcd of the pair of expressions

STALIN [3.7K]

$\frac{2}{7} {x}^{10} {y}^{4} \: and \: \frac{2}{14} {x}^{8} {y}^{7} \\ lcd = 14 {x}^{10} {y}^{7}$
Answer is
$14 {x}^{10} {y}^{7}$

When it's powered numbers, remember to choose the one with the largest power. For example,
${x}^{10}$
And
${x}^{8}$
Choose 10, same goes to y, where you choose 7 not 4 since 7 is larger.

Hope this helps. - M

Do even numbers have more factors in odd numbers or do i numbers have more factors than even numbers

Serggg [28]

It is because even numbers always have a factor of two, and therefore, larger composite even numbers will have factors of two and other even numbers based around two, such as 4, 8, 16, 32, and so on. On the other hand, numbers which are odd can have factors of 3, 5, and 7 for example, and their numbers based around them(3, 9, 27; 5, 10, 15; 7, 49, 343; and so on). If we look into it, notice how for odd numbers the space between the numbers based around 3, 5, and 7 are increasingly further apart. This is the reason why less large odd integers to have numerous factors. It is because odd numbers cannot have the prime factor 2, this will reduce their factor number. And is is also because even numbers are already divided by 2, this will give them more factors over the odd numbers.

4) 8(-2 + 2n) + 3n = 40 +5n

Nikitich [7]

Answer:

use the distributive property to distribute the 8

-16+16n+3n=40+5n

-16+19n=40+5n

-16=40+5n-19n

-16=40-14n

-14n+40= -16

-14n= -16-40

-14n= -56

n= -56/-14

n= 4

Question 2.2. Which ordered pairs make the inequality true?

Question 2.2. Which ordered pairs make the inequality true?2x + y > –4The solutions are (-1, 2) and (1, -5), look at the graph in the attachment.

Question 3.3. What is the slope of the line represented by the equation?

There is no equation

Question 4.4. What is the slope of the line represented by the equation 6x - 3y = 4?

Convert to slope-intercept form:

6x - 3y = 4

Subtract 6x to both sides:

-3y = -6x + 4

Divide -3 to both sides:

y = -6/-3x + 4/-3

Simplify:

y = 2x - 4/3

Now it's in slope intercept form, y = mx + b, where 'm' is the slope. So the slope here is 2.

Question 5.5. What is the simplified form of the expression?

15y - 3(4y + 10)

Distribute -3 into the parenthesis:

15y - 12y - 30

Combine like terms:

3y - 30
