When graphing the equation y=-3x+2, a student plotted the y-intercept at 2, then moved down three units and to the left 2 units

because the slope is negative, so both rise and run are negative. Find this error and correct it.

Answer:

The error is founded in the slope, specifically in the run.

When seen a negative slope, that only applies to the rise but <u>not</u> the run.

Instead, the student should run 1(not 2) units to the <u>right</u>.

The slope had not mentioned any 2 in the run.

So it would sound like down 3, over 1, starting from 2.

The y intercept at 2 is correct. This is the location (0,2)

The slope is -3 or -3/1, meaning that we move down 3 and to the right 1 unit. Doing so has us go from (0,2) to (1,-1). Plot these two points together on the same xy grid and draw a straight line through the two points.

If you run for 0.4 hours at 7 mph, how fast should you walk during the next 0.8 hours to have the average speed of 5 mph?
Fantom [35]

Answer:

4 mph

Step-by-step explanation:

The average speed of an object is given by the total distance covered by the time taken:

v=\frac{d}{t}

where

d is the total distance covered

t is the time taken

in the first part, the person runs for 0.4 hours at a speed of 7 mph, so the distance covered in the 1st part is

d_1 = v_1 t_1 = (7)(0.4)=2.8 mi

Then the distance covered in the second part is d_2, so the total distance is

d=2.8+d_2 (1)

The total time elapsed is 0.4 hours (first part) + 0.8 hours (second part), so

t=0.4+0.8=1.2 h

So we can write the average speed as

v=\frac{2.8+d_2}{1.2} (1)

We want the average speed to be 5 mph,

v = 5 mph

Therefore we can rearrange eq.(1) to find d2:

d_2 = 1.2v-2.8 = (1.2)(5)-2.8=3.2 mi

And therefore, the speed in the second part must be

v_2=\frac{d_2}{t_2}=\frac{3.2}{0.8}=4 mph

Classify the triangle by its angles.
dedylja [7]

Answer:

29°: Acute 90°: Right 61°: Acute

Step-by-step explanation:

If an angle is less than 90 degrees, it is acute. If it is greater than 90 degrees, it is obtuse. If it is exactly 90 degrees, it is right.
