Answer:B

Step-by-step explanation:

Mark two points; (3,3) & (0 , 1)

$Slope =\dfrac{1-3}{0-3}\\\\=\dfrac{-2}{-3}\\\\\=\dfrac{2}{3}$

y = mx + b

Plugin x = 0 and y = 1

1 = 0 + b

1 = b

$y=\dfrac{2}{3}x+1$

A, a +4,a+8,... write the nth term of sequence in terms of the first term of the sequence

IgorC [24]

a1 = 2*5

a2= 2*2*5

a3= 2*3*5

...

an=2n -*5

u1 = a

u2 = a +4

u3 = a + 2 * 4

u4 = a + 3 * 4

...

un = a + ( n - 1 )* 4

BRIA is a rectangle. AN=5. NR=x-3. please solve for x, NR, and BI

Lena [83]

Answer:

x=8

NR=5 units

BI=10 units

Step-by-step explanation:

In a rectangle BRIA

AN=5 units

NR=x-3

We have to solve for x , NR and BI.

We know that

Diagonals of rectangle bisect to each other.

BI and AR are the diagonals of rectangle BRIA and intersect at point N.

AN=NR

$5=x-3$

$x=5+3=8$

$x=8$

Substitute the value of x

NR=8-3=5

By property of rectangle

BI=AR=AN+NR=5+5=10 unit

BI=10 units
