1. $y=7x-1$

2. $y=3x+b$
<u> </u><u>Sub (1, -5) into equation to find '</u><em><u>b'</u></em><u />
$-5=3(1)+b$
$-8=b$

$y=3x-8$

3. $x=-7$

There are (4^9)5 ⋅ 4^0 books at the library. What is the total number of books at the library?

LenKa [72]

Your answer is B. You multiply 5 by the exponents and 4^0 is just 1, so 4^45•1=4^45. Hope this helped!

Find the distance between the points (4,3) and (2,-1). Express your answer in simplest radical form.

Kamila [148]

Answer : B

the distance between the points (4,3) and (2,-1)

We apply distance formula

$d^2= (x_2-x1)^2 + (y_2-y_1)^2$

(x1,y1) is (4,3)

(x2,y2) is (2,1)

$d^2= (2-4)^2 + (-1-3)^2$

$d^2= (-2)^2 + (-4)^2$

d^2 = 4+16 = 20

Take square root on both sides

So $d=2\sqrt{5}$

the distance between the points (4,3) and (2,-1) is 2sqrt(5)
