okay so the problem is "A circle is centered at the point (-3,2) and passes through the point (1,5). The radius of the circle is

Nesterboy [21]

Answer:

A circle is centered at the point (-3,2) and passes through the point (1,5). The radius of the circle is (5 ) units. the point (-7, -1) and point (-7, 5) lies in this circle.

Step-by-step explanation:

equation of circle is

(X-center_X)^2 + (y-center_Y)^2 = r^2

==> (x+3)^2 + (y-2)^2 = r^2

Now it passes 1,5 so

4^2+3^2 = 5^2

==> r = 5

when x = -7

y = -1 or 5

Answer:

Option C

Step-by-step explanation:

${ (\frac{ {x}^{4} }{ {7}^{ - 8} } ) }^{ - 7}$

$= \frac{ {x}^{4( - 7)} }{ {7}^{( - 8)( - 7)} }$

$= \frac{ {x}^{ - 28} }{ {7}^{56} }$

${x}^{ - 28} \times {7}^{ - 56}$

X+4Y=-8 find the x intercept: find the y intercept: graph the line.

galben [10]

Answer:

x-intercept = (-8, 0)

y-intercept = (0, -2)

Step-by-step explanation:

Given linear equation is: x + 4y = - 8

For x - intercept: Plug y = 0 in the above equation.

$\implies x +4(0) = -8\\\\\implies x +0 =-8\\\\ \implies x = -8\\\\ \boxed{\red{\bold{\implies x- intercept = (-8,\:0)}}}$

For y - intercept: Plug x = 0 in the given linear equation.

$\implies 0 +4y = -8\\\\\implies 4y=-8\\\\ \implies y = \frac{-8}{4}\\\\ \implies y = -2\\\\ \boxed{\purple{\bold{\implies y- intercept = (0,\:-2)}}}$
