Answer:

y = 8x

Step-by-step explanation:

1. First, we need to know what slope-intercept form is. The slope-intercept form of any linear equation is y = mx + b, where y = y-coordinate, m = slope, x = x-coordinate, and b = y-intercept.

2. To find the slope, let's take the two points (0,0) and (10,80) and plug their values into this formula: \frac{y_2-y_1}{x_2-x_1}

  • \frac{80-0}{10-0}
  • \frac{80}{10}
  • 8\\

3. Now that we know our slope, our equation should look like this so far: y = 8x + b.

4. Since b is the y-intercept, we can say that b = 0 because the line intersects with the y-axis at (0,0).

5. Therefore, we get an equation of y = 8x or y = 8x + 0.

Which is longer 2 meters or 200 cent a meters or 2.05 meters
Yuri [45]
Solving this requires use of conversions

we already know that
2.05 m > 2 m

all that's left is the question
200 cm vs. 2.05 meters

I we know our equivalencies, we know that
100 cm = 1 m

if this is so then
200 cm = 2 m

we already know that
2.05 m > 2 m

so it must also be that
2.05 m > 200 cm

2.05 \: meters

Scientists want to know the total trout population in a part of Lake Michigan. They tagged and released 200 trouts back into the
blondinia [14]
The estimate would be 1200.

We will set up a proportion for this.  10 out of 60 of the sample were tagged, so that is the first ratio.  The 200 that were tagged would be in the numerator of the second ratio (10 was the portion tagged, and 200 is the portion tagged, so they both go on top).  We do not know the total number so we use a variable:

10/60 = x/200

Cross multiply:

10*x = 60*200
10x = 12000

Divide both sides by 10:
10x/10 = 12000/10
x = 1200

BEST ANSWER GETS BRAINLIEST!!!!!!!!
Ad libitum [116K]

Answer:

(x + 6, y + 0), 180° rotation, reflection over the x‐axis

Step-by-step explanation:

The answer can be found out simply , a trapezoid has its horizontal sides usually parallel meanwhile the vertical sides are not parallel.

The horizontal parallel sides are on the x-axis.

Reflection over y- axis would leave the trapezoid in a vertical position such that the trapezoid ABCD won't be carried on the transformed trapezoid as shown in figure.

So option 1 and 2 are removed.

Now, a 90 degree rotation would leave the trapezoid in a vertical position again so its not suitable again.

In,The final option (x + 6, y + 0), 180° rotation, reflection over the x‐axis, x+6 would allow the parallel sides to increase in value hence the trapezoid would increase in size,

180 degree rotation would leave the trapezoid in an opposite position and reflection over x-axis would bring it below the Original trapezoid. Hence, transformed trapezoid A`B`C`D` would carry original trapezoid ABCD onto itself

Divide.<br> Write your answer in simplest form.<br> 1/9÷5/4=
irina [24]

Answer:

4/45

Step-by-step explanation:

when dividing fractions, you multiply the first fraction by the second fraction's reciprocal :

1/9 divided by 5/4

1/9 multiplied by 4/5

essentially, you switch the signs from division to multiplication, and reverse the second fraction.

1/9 multiplied by 4/5

1/9*4/5 = 4/45
