Choose the point slope form of the equation below that represents the line that passes through the point (6,-3) and has a slope

yulyashka [42]

The equation of a line that passes through the point (x1,y1) and has a slope of m is y-y1=m(x-x1)
given
(6,-3)
(x1,y1)
and slope is 1/2
y-(-3)=1/2(x-6)
y+3=1/2(x-6)
that is point slope

Find the value of x. Then find the measure of each labeled angle.

Nat2105 [25]

Answer:

x = 70; the labeled angles are 110º and 70º.

Step-by-step explanation:

The full degrees will add up to 180º. There are 2x and +40.

Equation: $2x+40=180$

Solve: $2x+40=180\\\\180-40=140\\\\2x=140\\\\x=70$

Since x=70, 70+40 will equal to 110.

Therefore, "x = 70; the labeled angles are 110º and 70º." is correct.

Can someone help me find the fa tor of (128m^2n^5 - 200m^4n^3)? <br>

Leona [35]

Answer:

$8m^2n^3$ , $4n-5m$ , and $4n+5m$

Step-by-step explanation:

$128m^2n^5-200m^4n^3$ <-- Given

$m^2(128n^5-200m^2n^3)$ <-- Factor out m²

$m^2n^3(128n^2-200m^2)$ <-- Factor out n³

$8m^2n^3(16n^2-25m^2)$ <-- Factor out 8

$8m^2n^3(4n-5m)(4n+5m)$ <-- Difference of Squares

Therefore, the factors are $8m^2n^3$ , $4n-5m$ , and $4n+5m$

Daca (x y) 5 =19 aflati x (y 5 )

cricket20 [7]

X+(y+5)=19,deoarece 19-5=14,dar14=x+y,apoi dam valori lui x si y astfel incit suma lor sa fie egala cu 14 de exemplu x=6 si y=8.Demonstram (6+8)+5=19sau 6+(8+5)=19.gata:)
