Graph the line using a point and a slope. Write the equation of each line.

Mandarinka [93]

Answer:

y = x - 2

Step-by-step explanation:

Parallel lines have the same slope, so the line will also have a slope of 1.

Plug in the slope and given point into y = mx + b to solve for b:

y = mx + b

-1 = 1(1) + b

-1 = 1 + b

-2 = b

Plug in b and the slope into y = mx + b

y = x - 2 is the equation

PLEASE HELP

Answer:

$12\sqrt{3}$ feet

Step-by-step explanation:

In a 30-60-90 triangle, the ratios of the side lengths of the triangle is $1:\sqrt{3} :2$

Where 1 is the shortest leg, root(3) is the longer leg, and 2 is the hypotenuse.

First we can set x equals to the length of the original pole, and so the shorter leg has a length of x/3 and using the ratio of side lengths, we can find that:

$\frac{x}{3} * \sqrt{3} = \frac{\sqrt{3} x}{3} = 12$

Solving for x, we find that

$x=\frac{36}{\sqrt{3} } = \frac{36 * \sqrt{3} }{\sqrt{3} * \sqrt{3} } = \frac{36 \sqrt{3} }{3} = 12\sqrt{3}$

So the length of the original pole would be $12\sqrt{3}$ feet

Need help with 3 and 4 consumer math plz

ratelena [41]

Answer:

3) C) $792.50

4) D) $707.50

Step-by-step explanation:

3) Home price = $ 253,600

Mortgage rate = 3.75% APR

Therefore, monthly rate = 3.75% divide by 12

= 0.0375/12

= 0.003125

1st month interest = principle * 0.003125

= 253600*0.003125

=$792.50

3) Answer: $792.50

4) You paid $1500

The first monthly interest = $792.50

Principal paid in the first month = 1500 - 792.50

= $707.50

Answer: D) $707.50

Thank you.

Answer:

Option C. -3x^2-13x-5

Step-by-step explanation:

we know that

To find how much greater is the area of room A than the area of room B. subtract the area of room B from the area of room A

$(5x^{2}-7x-6)-(8x^{2}+6x-1)\\ \\= (5x^{2}-7x-6)-8x^{2}-6x+1\\ \\=(5x^{2}-8x^{2})+(-7x-6x)+(-6+1)\\ \\=-3x^{2} -13x-5$
