Mathematics
1 answer:
Slav-nsk [51]3 years ago

Answer:

y - 35 = 6(x - 5)

Step-by-step explanation:

The point-slope equation of a line is

y - y_1 = m(x - x_1) ,

where

m = slope = \dfrac{y_2 - y_1}{x_2 - x_1}

and the point is

(x_1, y_1)

Let's find the slope.

m = slope = \dfrac{-31 - 35}{-6 - 5}

m = \dfrac{-66}{-11}

m = 6

We are asked to use the first point in the equation, so

x_1 = 5  and y_1 = 35

The equation is:

y - 35 = 6(x - 5)

Find angle B. What is angle B.
julsineya [31]

Answer:

B=45 Degrees

Step-by-step explanation:

You can use law of sines to answer. Law of Sines states that \frac{sin(a)}{A} =\frac{sin(b)}{B}. That means that \frac{sin(60)}{4\sqrt{6} }=\frac{sin(b)}{8}. Multiplying 8 to both sides gives us \frac{8sin(60)}{4\sqrt{6} }=sin(b). By using inverse of sin, we get b =  sin^{-1} (\frac{8sin(60)}{4\sqrt{6} } ). Plugging that into a calculator gives us b=45 degrees.

1. Gavin and Seiji both worked hard over the summer. Together, they earned a total of $425. Gavin earned $25 more than Seiji. Ho
Gre4nikov [31]
Let x = the amount that Seini earned
Then x + 25 = the amount that Gavin
The amount Gavin earned would also = 425 - x (your directions asked you to have 2 equations.)
Together they earned 425:
x + (x + 25) = 425
2x + 25 = 425
2x = 400
Now divide both sides by 2 to find x.

Use all of this data to satisfy the directions.
