Tim and Caitlin are preparing to get married. Caitlin has a car payment of $300 per month, which is 10% of her monthly income. A

Misha Larkins [42]

Answer:

A. $2,000

Step-by-step explanation:

Let x represent Caitlin's monthly income and y represent Tim's monthly income.

We have been given that Caitlin has a car payment of $300 per month, which is 10% of her monthly income.

We can represent this information in an equation as:

$\frac{10}{100}x=300$

$0.10x=300$

$x=\frac{300}{0.10}$

$x=3000$

Therefore, Caitlin's monthly income would be $3000.

We are also told that after Caitlin is married to Tim, her car payment will only be 6% of their combined monthly income.

This means that 6% of x plus y is equal to 300.

$\frac{6}{100}(x+y)=300$

$0.06(3000+y)=300$

$180+0.06y=300$

$180-180+0.06y=300-180$

$0.06y=120$

$y=\frac{120}{0.06}$

$y=2000$

Therefore, Tim's monthly income is $2,000 and option A is the correct choice.

For what value of x will the line passing through the points A(x+14, 5) and B(2−3x, 8) be vertical?

trapecia [35]

Answer:

x=-3

Step-by-step explanation:

we know that

The slope of a vertical line is undefined

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

we have

A(x+14, 5) and B(2−3x, 8)

substitute

$m=\frac{8-5}{(2-3x)-(x+14)}$

$m=\frac{3}{2-3x-x-14}$

$m=\frac{3}{-4x-12}$

so

If the slope is undefined

then

The denominator must be equal to zero

$-4x-12=0$

solve for x

$4x=-12\\x=-3$

Hey:) can you please help me posted picture of question

AnnyKZ [126]

Answer:
16x² - 49

Explanation:
To answer this question, we will multiply each term from the first bracket by each term from the second bracket and then combine like terms to get the final expression.

This can be done as follows:
(4x - 7)(4x + 7)
4x(4x) + 4x(7) - 7(4x) - 7(7)
16x² + 28x - 28x - 49
16x² - 49

Another easier way to solve this is to note that the given brackets can be solved using the difference between two squares.
The rule can be stated as follows:
(a + b)(a - b) = a² - b²

Comparing this to the given brackets, we will find that:
(4x + 7)(4x - 7) = (4x)² - (7)² = 16x² - 49

Hope this helps :)
