Answer:

2.5  × 10^6 times larger

Step-by-step explanation:

Each step bacteria =  3 * (10^(-7)) meters = 0.0003 millimeters    Joes step bacteria = 0.75 meters.= 750 millimeters We then divide = 750/0.0003 = 2500000 =  2.5  × 10^6

Answer:

-12

Step-by-step explanation:

So to start we need to know what makes a line parallel. In an equation we know that for lines to be parallel they must have the same slope(m).

Then, we  need to know the slope-intercept form of an equation. The slope intercept form is y=mx+b where m is the slope of the line and b is the y-intercept. In this problem where can see the second equation is already in this form.

Now that we know we need to find the slope, and we know that the second equation is in slope-intercept form we're going to convert the fist equation into the correct form.

To do this, we know we need to make sure y is the only thing on the left side of the equal sign. Currently, on the left side of the equal sign we have -\frac{1}{2} y so we have to divide both sides by -\frac{1}{2} to get y=-12x -20

Now that we have it converted to slope-intercept form, we are going to look for what represents the slope or m in the equation. In this case the slope would be -12, so any line with a slope of -12 will be parallel.

Answer:

y=-3x+4

Step-by-step explanation:

The question is asking for the equation in slope-intercept form. This is y=mx+b where m is the slope and b is the y-intercept.

The slope can be found by counting the units in between two points on the graph. Remember that slope is rise over run or y/x. Two points on the graph are (2,-2) and (1,1). The y is increasing by 3 while x is decreasing by 1. This means the slope is -3.

The y-intercept is where the line intersects with the y-axis. In this case, that point is (0,4). Therefore, b=4.

The final answer is y=-3x+4.
