Graph the line with the slope -3/4 passing through the point (4,-1)
-Dominant- [34]

Answer:

Step-by-step explanation:

Plot the point (4, -1) in the 4th Quadrant.

The slope (-3/4) tells us what to do next:

With your pencil point initially on (4, -1), move it 4 units to the right, to (8, -1).

With your point initially on (8, -10, move it down 3 units, to (8, -4).  Plot (darken) (8, -4).

Draw a line through (4, -1) AND (8, -4)

For a two week period, John and Amanda had the following transactions occur to their checking account: a deposit of $1,644.50; c
Andru [333]

deposit of $1644.50 is (gain)

check written and deposit are (loses)  subtracted


so total of 3 checks :-   190$   +  45$  +  7.50$   =   242.50$

total of 4 debit cards :-    30$  +  5.59$  +  7.20$  + 21.30$  = 64.09$

total lose amount ( credits + debits )  =   242.50 $  +  64.09$ =  306.59$


Ending balance = Total amount - total loses =  

         1644.50$ -  306.59 $ =  1337.91$

If (−4, 11) and (−6, 5) are the endpoints of a diameter of a circle, what is the equation of the circle?
lora16 [44]

Answer:

A. (x+5)^2+(y-8)^2=100

Step-by-step explanation:

1. The standard form of the equation of a circle is (x-h)^{2} + (y-k)^2=r^2

2. To find the center we require the  midpoint   of the  2 given points

center =[\frac{1}{2}(-4-6),\frac{1}{2}(11+5)]

=(-5,8)

3. The radius is the distance from the centre to either of  the 2 given points calculate the radius using the  distance formula

d= \sqrt{(x_{2}+x_{1})^{2} +(y_{2}-y_{1})^{2}

let (x_{1},y_{1})= (-5,8) \\ and (x_2,y_2)=(-4,11)

r=\sqrt{(-4+5)^2+(11-8)^2} =\sqrt{81+9}=10

--> (x-(-5)^2+(y-8)^2=10^2

--> (x+5)^2+(y-8)^2=100
