What is the value of y?
NNADVOKAT [17]

Answer:

b-65

Step-by-step explanation:

They give you 130 and so to get the next measure its 180-130 and you get 50. So the blank angle is 50. Then the next two angles are y which means theyre equal to each other so they have to be the same number. Get 180 again and subtract 50 and get 130. Split 130 in half and get 65.

What is the equation of the line in point-slope form?
evablogger [386]

Answer:

y +500 = -\frac{1}{5}(x - 100)

Step-by-step explanation:

Given

The attached graph

Required

Determine the equation in point slope form

From the graph, we have the following points;

(x_1,y_1) = (-400,-400)

(x_2,y_2) = (100,-500)

First, we calculate the slope (m):

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

m = \frac{-500 - (-400)}{100- (-400)}

m = \frac{-500 +400}{100+400}

m = \frac{-100}{500}

m = -\frac{1}{5}

The equation is then calculated using:

y - y_2 = m(x - x_2)

Substitute x and y values

y - (-500) = -\frac{1}{5}(x - (100))

y +500 = -\frac{1}{5}(x - 100)

If the sum of $1! + 2! + 3! + \cdots + 49! + 50!$ is divided by $15$, what is the remainder?
kompoz [17]

Answer:

  3

Step-by-step explanation:

All factorials 5 and above are evenly divisible by 15, so have no remainder. Thus, you are interested in ...

  mod(1! +2! +3! +4!, 15) = mod(1 +2 +6 +24, 15)

  = mod(33, 15) = 3

The remainder is 3.
