The equation of the line is

−x

x−x

−y

y−y

Here (−3,4)≡(x

),(4,5)≡(x

)

∴

4+3

x+3

5−4

y−4

⇒

x+3

y−4

⇒x+3=7(y−4)

⇒x+3=7y−28

⇒x−7y+3+28=0

⇒x−7y+31=0

In 2010 the national debt was around 13,316,000,000,000 dollars. How would this number be written in scientific notation?

Oksana_A [137]

Answer:

a) 1.33*10^13

Step-by-step explanation:

In scientific notation, we have the starting number which is between 1 and 10 which is multiplied by a power of 10.

The starting number is the first digit, then a decimal is placed with the next two digits. The power of 10 is determined by counting from 0 to the first digit.

So 1.33*10^13 is the answer

20. Steve has $30 and he earns $5 an hour parking cars. Write an equation to represent how much

patriot [66]

Answer:

$30+m($5 x h)

he will be working for 21 h

Step-by-step explanation:

So, Steve has $30, so you want to add that amount to the amount he earn, which is $105.

$5 times 21 is $105

h = 21

but we still need for m but, we already have m

m = $105

The coordinates of the vertices of quadrilateral ABCD are A(0, −4) , B(−4, 3) , C(3, 4) , and D(6, −1) . Drag and drop the choic

Art [367]

Answer:

The slope of AB is -7/4, the slope of BC is 1/7 , the slope of CD is 5/3, and the slope of AD is 2. So, Quadrilateral ABCD is neither a parallelogram nor a trapezoid because neither pair of opposite sides are parallel.

Step-by-step explanation:

Since, a quadrilateral having,

One pair of parallel opposite sides is Trapezoid,

While, having two pair of parallel opposite sides is parallelogram.

Since, the slope of a line segment having the end points $(x_1, y_1)$ and $(x_2, y_2)$ is,

$m=\frac{y_2-y_1}{x_2-x_1}$

Here, the vertices of the quadrilateral ABCD are A(0, −4) , B(−4, 3) , C(3, 4) , and D(6, −1),

Slope of AB = $\frac{3+4}{-4-0}=-\frac{7}{4}$

Slope of BC = $\frac{4-3}{3+4}=\frac{1}{7}$

Slope of CD = $\frac{-1-4}{6-3}=-\frac{5}{3}$

Slope of AD = $\frac{-1+4}{6-0}=\frac{3}{6}=2$

Hence, Quadrilateral ABCD is neither a parallelogram nor a trapezoid because neither pair of opposite sides are parallel.

First, set 2x+7 equal to 3x-7 since they are the same angle due to the parallel lines.

2x+7=3x-7
x=14

Then, since 2x+7 and 12y+1 equals 180, put it together to find y:

(2x+7)+(12y+1)=180
(2(14)+7)+(12y+1)=180
12y+1=145
12y=144
y=12

So, x=14 and y=12. Your answer should be C!
