Answer:

20m+189

Step-by-step explanation:

Firstly I let the numbers be m,m+1,m+2......m+19. Then I added all the numbers and put variables and constant at different portions and added all variables which were 20(m) and all constant were equal to 189...so the answer is 20m+189

Consider the following system of equations. -10x2-10y2=-300 5x2+5y2=150 Which statement describes why the system has infinite so

scoundrel [369]

Answer:

The equations represent circles that result in the same graph.

Step-by-step explanation:

we have

$-10x^{2}-10y^{2}=-300$

Divide by -10 both sides

$x^{2}+y^{2}=30$ -----> equation A

This is the equation of a circle centered at origin with radius $r=\sqrt{30} \ units$

and

$5x^{2}+5y^{2}=150$

Divide by 5 both sides

$x^{2}+y^{2}=30$ -----> equation B

This is the equation of a circle centered at origin with radius $r=\sqrt{30} \ units$

equation A and equation B are equal

therefore

The system has infinite solutions, because the equations represent circles that result in the same graph.

Find the distance between points (2, 9) and (5, 4) to the nearest tenth

Troyanec [42]

Answer:

$Distance = 5.8$

Step-by-step explanation:

$d=\sqrt{(4-9)^{2} } { (5-2)} ^{2} \\$

$d = -5^{2} + 3^{2}$

$d= 25 + 9$

$d= \sqrt{34}$

$distance = 5.8$
