Write an equation in slope intercept form for the line that passes through (2,-2) and is parallel to y=-5/2x+5

Answers

[tex]y=mx+b\\y=x-2[/tex]

Only y= x - 2 intercepts x-axis at 2 and y-axis at -2. Thus meaning that they intercept oppositely.

Find if both graphs are parallel, that means the equation must be false.

[tex]x-2=-\frac{5}{2}x+5[/tex]

Multiply whole equation by 2 to get rid of the fractional 2.

[tex]2x-(2)(2)=-\frac{5}{2}(2)(x)+5(2)\\ 2x-4=-5x+10\\2x-4+5x-10=0\\7x-14=0\\7x=14\\x=2[/tex]

Well, that doesn't seem to be parallel. This is called one solution answer. Both graphs intercept at (2,0). There are no linear graphs that intercept at (2,-2) except for y = x-2 so there are no graphs with (2,-2) that are parallel to the equation y = -5x/2+5

· Josh Duchene worked at three jobs in three weeks. In the first week, he earned $360. In the next week, he
was paid $345. In the third week, he was paid $315. What average pay per week did Josh earn for these
three weeks?

Answers

$340 add all of the values up and divide by the total number of weeks

The average pay per week Josh earned for three weeks is $340.

What is an average?

The term average is the sum of all the numbers divided by the total number of values in the set.

Now it is given that,

Pay received in first week = $360

Pay received in second week = $345

Pay received in third week = $315

So,

Total money earned in three weeks = $360+$345+$315

                                                            = $1,020

Now number of weeks  = 3

therefore, average pay per week = Total money earned in three weeks/number of weeks

⇒ average pay per week = $1020/3

⇒ average pay per week = $340

Thus, the average pay per week Josh earned for three weeks is $340.

Walking for Exercise Walking is a good form of exercise, as it provides many health benefits. However, making walking beneficial requires understanding and planning.Proper Technique While walking may seem like a relatively simple task, walking for exercise is different. The head should be up and the shoulders should be relaxed. Arms should be slightly bent and swung back and forth as one walks. While the heart should not be racing as one walks, the pulse should be elevated.Planning Walking for exercise should be planned, just like any other time of exercise. Set aside a certain amount of time each day. Sixty minutes of physical activity daily is recommended. However, if walking is a new form of physical activity, it is acceptable to start with a short amount of time and increase the time spent walking each day. Remember, physical activity is important for one's health, and walking is a good form of exercise.1Which statement is an important point in the passage?A.
