Answer:
a. m = 2; y intercept = (0, 4); y = 2 x + 4
Step-by-step explanation:
The slope can be found using the formula ...
m = (y2 -y1)/(x2 -x1)
m = (18 -4)/(7 -0) = 14/7
m = 2
The y-intercept is the first given point: (0, 4).
The equation for the line in slope-intercept form is
y = mx + b
Here, we have m=2 and b=4, so the equation is ...
y = 2x +4
Answer:
6 miles
Step-by-step explanation:
60 miles : 5 inches
12 miles : 1 inch
6 miles : 1/2 inch
whatever you do to one side of the ratio you have to do to the other.
to get from 1 to a 1/2 you divide by 2, so you do 12 divided by 2 which is 6.
Answer:
80000
Step-by-step explanation:
Significant figures are any number but zeroes.
However, in some cases, zeroes also count as significant figures.
- Zeroes are significant figures when between other non-zero numbers.
- Zeroes are significant when you see a dot on the right indicating that zero is not a place holder.
- They are <u>not</u> significant when serving as place holders, such as zeroes on the right side of a number. For example, .004 has 1 sig fig. The 2 zeroes on the left aren't sig figs because they're just place holders.
- Zeroes on the <u>right</u> side of a decimal are also significant.
Hope this helps but I think there is a 1/4 or a 25% chance of somebody winning a prize.
