the distance between two planets in the solar system is 560,800 miles. express the distance in scientific notation
Step2247 [10]
The distance in scientific notation is 5.6x10^5 miles. ^ is to the power of. Start from the right of a number and count the number of spaces till you get between the first two numbers, and that is how you get your exponent. It would be a different case if you had a decimal number though. For example the scientific notation of 0.00000256 would be 2.5x10^-6. You would count the number of spaces from the left to right and the exponent would be a negative.

What is the equation of a line that passes through point r(−3, 5) and has a slope of 4?
nexus9112 [7]
The equation of any line is:
y=mx+b  m is slope.

We just need to put inside of equation x=(-3) and y=5:
5=4*(-3)+b
17=b

It follows that equation of a line is:
y=4x+17

Which function BEST expresses the linear relationship displayed by the scatter plot?
Harrizon [31]

Answer:

C

Step-by-step explanation:

We want a line of best fit, which means we want to create a line that the data points will lie closest to.

One thing we can do is find the slope between the bottom-leftmost point and the top-rightmost point. This is because if we were to draw a line connecting these two, it will cut through the data quite well.

Those two points are (9, 15) and (16, 18), so the slope is change in y divided by the change in x:

(18 - 15) ÷ (16 - 9) = 3 ÷ 7 ≈ 0.4

Eliminate A and B.

Now we need to determine the y-intercept. This needs no calculations; simply look at the graph: there's no way a line cutting through the y-intercept point of (0, 18) will perfectly match the data points; instead it must be a y-intercept lower than 18. So, eliminate D.

The answer is C.
