(19,-9) (-7,-15) in slope intercept form

never [62]

Answer:

$y=\frac{3}{13}x-\frac{174}{13}$

Step-by-step explanation:

slope:

$m=\frac{-15-(-9)}{-7-19} =\frac{-15+9}{-26} =\frac{-6}{-26} =\frac{3}{13}$

Equation, with the point (19, -9):

$y-(-9)=\frac{3}{13} (x-19)$

$y+9=\frac{3}{13} x-\frac{57}{13}$

$y=\frac{3}{13} x-\frac{57}{13} -9$

$-9=-9(\frac{13}{13} )=-\frac{117}{13}$

$y=\frac{3}{13}x-\frac{174}{13}$

A pizza stand offer both hand- tossed and pan pizza. customer can add any combination of the six available topping.

photoshop1234 [79]

The correct choice would be 128.

If there are 6 options and the person can pick any number of toppings, we need to know the number of subsets that can be formed with 6. That would be 2^6 or 64.

Since there is a pan or hand-tossed option, we need to multiply 64 by 2 to find the total.
64 x 2 = 128

Rotation 180 counterclockwise around the origin of the point (-3,-7)

yaroslaw [1]

Answer: (3 , 7)

Step-by-step explanation: When rotating a point 180 degrees counterclockwise about the origin our point A(x,y) becomes A'(-x,-y). So all we do is make both x and y negative. Since x and y are already negative, they become positive due to the double negative rule.

A theater group is having a carwash fundraiser. The group can only wash 45 cars with the amount of soap they purchased. Each car

Answer:

<h2>The domain for this function is $c > 0$ where $c \in Z$ .</h2>

Step-by-step explanation:

The given function is

$f(c)=7c$

Where $c$ represents cars. This function models the profits they make.

Now, as you can deduct already, we can define to different domains, the mathematical one and the reasonable one.

The reasonable domain is about all the useful values to the problem. For example, as we are talking about car, they can't wash -5 cars, so negative numbers are excluded. Similarly, they can't wash 6.75 cars, because that would imply an incomplete job.

Therefore, the domain for this function is $c > 0$ where $c \in Z$ .

(Notice that we specify that the independent valur can only use whole positive numbers only).
