Answer:

$8.51x10^{-3}cm$

Step-by-step explanation:

In order to add or subtract numbers in scientific notation, the powers of ten must have the same exponent. In this caes the diameter of an average human body cell is a power of -4 and the diameter of a plant cell is a power of -3. In order to add them, we can move the decimal over for the body cell diameter:

$5.1x10^{-4}=0.51x10^{-3}$

Add the two values: $0.51x10^{-3}+8x10^{-3}=8.51x10^{-3}cm$

Pls help ASAP due tonight math

Answer:

The equation of the line is y=1.4x+6.8

Step-by-step explanation:

Given 2 points on the graph, you can find the slope using the equation: $m=\frac{y2-x2}{y1-x1}$ . The 2 points are (-7, -3) and (-2, 4). X1 is -7, X2 is -2, Y1 is -3, Y2 is 4. The slope would be 1.4 once you plug in the numbers to the equation to finding the slope. Once you find the slope, use one of the points to find the y-intercept along with the slope you found and the y-intercept will be 6.8.
