Answer:
Graphing
Step-by-step explanation:
1) You can graph this equation by using y=mx+b. You can replace that equation with y=3x-1.
M=3
X=x
B=-1
On a graph you would down 1 since it's negative and make a point. Then you would put a 1 under the 3 to make it a fraction. 3/1. Then you would divide 1 by 3 (1 ÷ 3). Then you would go to the right 0.33 because it's positive, and the up 1. Then you would make a second point.
This would only give you one line which wouldn't give you an intersection.
Answer:
B?
Step-by-step explanation:
Because the number between 10 is 5 going across and the one that goes up and down you can count 3 down and thats where your point it
Answer:
6.75 × 10^3
Step-by-step explanation:
Move the decimal 3 times to the left so that the resulting number, m = 6.75, is greater than or equal to 1 but less than 10
Since we moved the decimal to the left the exponent n is positive
n = 3
Write in the scientific notation form, m × 10^n
6.75 × 10^3
