Plotting these two equations on a graph.<br><br> p=6-2q<br> p=4+q

Mekhanik [1.2K]

Put into slope intercept form, y=mx+b where m=slope
p=-2q+6
slope is -2
subsitute values for q and get values for p
q=0, p=6
(q,p)
(0,6)
(1,4)

p=q+4
slope is 1
subsitutte
q=0,p=4
(q,p)
(0,4)
(1,5)

below are the graphs

X^2+(y+)4^2=64 khan academy

Tems11 [23]

Answer: The center is 0,4

Step-by-step explanation:

Use this form to determine the center and radius of the circle:

(

x-h)^2+(y-k)^2=r^2

Match the values in this circle to those of the standard form. The variable r represents the radius of the circle, h represents the x-offset from the origin, and k represents the y-offset from origin:

r=8

h=0

k=4

The center of the cirle is found at (h,k): (0,4)

The radius is 8

If x=2k + 1, y=k - 1 is a solution of the equation 2x - 3y + 5=0. find the value of k.

devlian [24]

Answer:

$x = 2k + 1 \\ y = k - 1 \\ given$

if u substitute the givens in the eqn we will get..

$2(2k + 1) - 2(k - 1) + 5 = 0 \\ 4k + 2 - (2k - 2) + 5 = 0 \\ 4k + 2 - 2k + 2 + 5 = 0 \\$

then collect like terms

$4k - 2k + 2 + 2 + 5 = 0 \\ 2k + 4 + 5 = 0 \\ 2k + 9 = 0$

$2k = - 9 \\ k = \frac{ - 9}{2}$
