Nina [5.8K]

Answer:

B(7,10)

Step-by-step explanation:

M(5,7)=(x ,y)\\A(3,4)=(x_1,y_1)\\B(x_2,y_2)\\\\Endpoint ;\\x = \frac{x_1+x_2}{2}\\ \\5 = \frac{3+x_2}{2}\\ Cross\:Multiply\\5\times 2 =3+x_2\\10=3+x_2\\10-3 =x_2\\7=x_2\\\\\\y = \frac{y_1+y_2}{2} \\\\7 = \frac{4+y_2}{2}\\ Cross\:Multiply\\7\times 2 =4+y_2\\14 =4+y_2\\14-4 =y_2\\10 =y_2\\\\\\B(7,10)

1/4(X-10)=2X+1 <br><br> what is X?
In-s [12.5K]

Answer: x=-2

Step-by-step explanation:

\frac{1}{4}(x-10)=2x+1

Distribute 1/4

\frac{1}{4}x-\frac{1}{4}(10)=2x+1

\frac{1}{4}x-\frac{5}{2}=2x+1

add 5/2

\frac{1}{4}x-\frac{5}{2}+\frac{5}{2}=2x+1+\frac{5}{2}

\frac{1}{4}x=2x+\frac{1*2+5}{2}

\frac{1}{4}x=2x+\frac{2+5}{2}

\frac{1}{4}x=2x+\frac{7}{2}

Subtract 2x

\frac{1}{4}x-2x=2x-2x+\frac{7}{2}

\frac{1}{4}x-2x=\frac{7}{2}

\frac{1-2*4}{4}x=\frac{7}{2}

\frac{1-8}{4}x=\frac{7}{2}

-\frac{7}{4} x=\frac{7}{2}

Multiply by the negative reciprocal of -7/4 which is basically inverting the fraction -4/7

(-\frac{4}{7} )-\frac{7}{4} x=\frac{7}{2}(-\frac{4}{7} )

x=-\frac{28}{14}\\ x=-2
