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.

write an equation of a line that is perpendicular to given line that passes through the given point 5y+2x=-15 T(5,-5)​
Oliga [24]

Step-by-step explanation:

The answer is on the bottom if you just wanna scroll down.

The first thing that you would want to do is turn the equation of the given line into slope-intercept form (it's just easier). To do that, you would want to isolate  y on either side. So subtract 2x and divide both sides by 5 and you get: y=-2/5x-3. After you do this, remember that perpendicular lines have the negative reciprical slope of the original line. So since the slope is -2/5, the slope of a perpendicular line would be 5/2. Now you have m=5/2 which is your slope! Now you can use slope point form which is y-y_1=m(x-x_1). You know your m which is 5/2. y-y_1=5/2(x-x_1). Since we know that the line passes through the point (5,-5) we can just plug the numbers in. y-(-5)=5/2(x-5). simplify everything: y+5=5/2(x-5). Remember, math is all about making things simple and easy. since the problem didn't say a specific type of equation, you can just put that as your answer!

Answer:

y+5=5/2(x-5)

Hope this helps! (If it's wrong, plz leave sum comments. thx lol)

For an annual membership fee of $500, Mr. Bailey can join a country club that would allow him to play a round of golf for $35. W
Elodia [21]

Answer:

20

Step-by-step explanation:

let the number of rounds of golf played for the cost to equal be x.

-It costs $35/ round when the membership of $500 is paid, hence, total annual cost is:

500+35x

#When membership is not paid, the annual cost is expressed as:

55x

#Since the cost should be equal after x rounds, we equate the two to solve for x:

500+35x=55x\\\\500=20x\\\\x=25

Hence, Mr Bailey has to play 20 rounds of golf for the cost in both scenarios to be equal.

Mrs gray bought some eggs. She boiled one half of them and poached one fourth of the remainder . she had 9 eggs left. How many e
Scorpion4ik [409]
To answer this item, we let x be the number of eggs in the beginning. The first half of the egg which were not boiled is represented through the equation is represented by x/2.

Next, the remainder of the egg which were not boiled nor poached is equal to 
             = (1/2)(3/4)x

Simplifying,
                 0.375x

Equating this to 9,
               0.375x = 9

The value of x from the equation is 24.

Answer: 24 eggs
