Answer:
The answer is definitely Option A
Answer:
Substitute y=x-2y=x−2 into y=-0.5x+4y=−0.5x+4.
x-2=-0.5x+4x−2=−0.5x+4
2 Solve for xx in x-2=-0.5x+4x−2=−0.5x+4.
x=4x=4
3 Substitute x=4x=4 into y=x-2y=x−2.
y=2y=2
4 Therefore,
\begin{aligned}&x=4\\&y=2\end{aligned}
x=4
y=2

Answer:
106.34%
Step-by-step explanation:
hay 24 personas en total (11 mujeres+13 hombres)
la probabilidad para que uno de los alumnos es un hombre es 13/24 (porque hay 13 hombres en la clase)
Entonces, si uno hombre está elegido, quedan 12 hombres, así que, la probabilidad si es un hombre es 12/23 (porque una persona ya está elegido y quedan 23 personas)
la probabilidad es 13/24+12/23=587/552=106.34% (Redondeado a la décima más cercana)
(lo siento mi español no es perfecto)
Distance formula between 2 points (x1,y1) and (x2,y2)
D=
D=29 and one point is (-5,5) and the other is (k,0)
sub
29=
29=
square both sides
841=
841=
minus 25 both sides
816=
square root both sides don't forget positive and negative roots
+/-4√51=-5-k
add 5 to both sides
5+/-4√51=-k
times -1 both sides
-5+/-4√51=k
the possible values for k are
k=-5+4√51 or k=-5-4√51
Answer:
B: 6 to the 10th over 7 to the 6th
Step-by-step explanation:
(6^5 / 7^3)^2
We know that (a /b) ^c = a^c / b^c
(6^5)^2 / (7^3)^2
We know that a power to a power is the powers multiplied a^b^c = a^(b*c)
6^ (5*2)/ (7^(3*2))
6^10/(7^6)
Since the bases are not the same, there is nothing else we can do
