The diameter of the average cell in the human body is 1 x 10-5 meters. The diameter of a grain of sand is about 2 x 10-4 meters.

The diameter of a human hair is about 0.000025 meters. The smallest known bacteria are from the genus Mycoplasma and can measure as small as 300 nanometers in diameter. Given that 1 meter = 1 x 109 nanometers, what is the diameter of the smallest bacteria, in meters? Give your answer in scientific notation and show your work.

A line passes through the point (-8, 7) and has a slope of negative 3/4Write an equation in slope-intercept form for this line.
Arlecino [84]

Answer:

y=-\frac{3}{4}x+1

Step-by-step explanation:

We do not have enough information for slope intercept form. But we can use the point-slope formula to find the information. The formula is y -y_{1} =m(x -x_{1}) where we substitute a point (x,y) for (x_{1},y_{1}).  

We have m=-3/4 and (-8, 7). We input m and x_{1} =-8\\y_{1}=7.

y-7=-\frac{3}{4} (x-(-8))\\y-7=-\frac{3}{4} (x+8)

We now simplify the parenthesis and solve for y.

y-7=-\frac{3}{4} (x+8)\\y-7=-\frac{3}{4}x+-\frac{3}{4} (8)

We convert 8 into a fraction with 1 as the denoinator.

y-7=-\frac{3}{4}x+-\frac{3}{4} (\frac{8}{1} )\\y-7=-\frac{3}{4}x+-\frac{24}{4}\\y-7=-\frac{3}{4}x+-6

We add 7 to both sides to isolate y,

y-7+7=-\frac{3}{4}x+-6+7\\y=-\frac{3}{4}x+1

This is slope intercept form. The line as slope -3/4 and y-intercept (0,1) or b=1.
