Answer: -6

Step-by-step explanation:

y=-3 so y+1 could be replaced by -3+1 which is -2 leaving your equation looking like this 2x-7(-2) next you want to multiply -7 and -2 to get -14. So now you have 2x-14, well x is four and 4x2 is 8 so your equation is now 8-14, which leaves you with -6. Hope this helps and have a good day!

A circle has its center at the origin, and (5, -12) is a point on the circle. How long is the radius of the circle?

kolezko [41]

(x-center)^2+(y-center)^2=r^2
x^2+y^2=r^2
(5)^2+(-12)^2=r^2
25+144=r^2
169=r^2
r=13

Which description is correct for the polynomial 4x^2+3x+5

Zepler [3.9K]

That is a quadratic trinomial.
Its largest degree is 2 (which makes it quadratic), and it has 3 terms separated by addition operators (which makes it trinomial).

Ten thousand times the sum of a number and seven hundred

Vera_Pavlovna [14]

Let x be the unknown number.

The sum of x and seven hundred is $x+700$

Ten thousand times this sum is $10000(x+700)$
