mel-nik [20]

Step-by-step explanation:

The scientific notation of any number is given by :

N=a\times 10^b

a is any real no and b is any integer

The scientific notation of 345,000,000 should be 3.45\times 10^8 but Jorden wrote 34.5×10⁷. He is incorrect. He should have shifted decimal before 4 such that power of 10 becomes 8.

Answer:

b.

( -3, -5)

Step-by-step explanation:

6x + 13 = 2x + 1

6x -2x = 1-13

4x = -12

x = -12/4 = -3

y = 6x + 13

y = 6(-3) +13 = -18+13 = -5

Line m passes through C(-2, 0) and D(1, -3). What is the equation of the line m in standard form?
Serga [27]
From general equation of a line;
y=mx+c
m=\frac{change in y}{change in x}
m=\frac{0--3}{-2-1}
m=-1
y=-x+c 
Finding value of c;
using point (-2,0)
0=-(-2)+c
c=-2
y=-x-2
