Solve for x-2a+7-3(-9-4a)​

Mathematics
1 answer:
Ksivusya [100]3 years ago
8 0

Answer: a=-3.4

Step-by-step explanation: you mean solve for a:)

-2a+7-3(-9-4a)=0        We would have to equal this equation to 0

-2a+7+27+12a=0         We multiply the -3 with the parentheses

10a+34=0                     Add the like terms, and subtract 34 from both sides

10a=-34                        Then divide both sides by 10

a=-3.4

Select interior, exterior, or on the circle (x - 5) 2 + (y + 3) 2 = 25 for the following point. (2, 3)
lozanna [386]
Standard equation of a circle: <em>(x-h)² + (y-k)² = r²</em> where <em>(h, k)</em> is the center and <em>r </em>is the radius. In the case of our equation here, <em>(x-5)² + (y+3)² = 25</em>, we can conclude that our circle has a center at (5, -3) and a radius of 5 units.

We can use the distance formula with the center (5, -3) and our point (2, 3) to see how far away they are...if the distance between them is less than the radius of the circle, it is on the interior. If it's equal, it's on the circle. If it's greater, it's on the exterior.

Distance = \sqrt{(y_2-y_1)^2+(x_2-x_1)^2}

Distance = \sqrt{(-3-3)^2+(5-2)^2}

Distance = \sqrt{(-6)^2+3^2}

Distance = \sqrt{36+9}

Distance = \sqrt{45}\approx6.7082

6.7082>5,\ so\ (2,3)\ is\ on\ the\ \boxed{exterior}
