justin and tyson are beginning an exercise program to train for football season. Justin weighs 150 pounds and hopes to gain 2 pounds per week. Tyson weighs 195 pounds and hopes to lose 1 pound per week. if the plan works in how many weeks will the boys weigh the same amount. what will the weight be

Answers

It will take Justin and Tyson 15 weeks to both be 180 pounds. You just do 150+2*15=180 and then you would do the other one 195-1*15=180 and they both equal the same.

it will take 15 weeks for them to be the same weight.

What is the solution set of {x | x < 2} ∪ {x | x ≥ 2}

Answers

The union of two sets is defined as all elements that are members of both sets.

The first set evaluuates to (...,...,...-2,-1,0,1) and the second eveluates to (2,3,4,5,...,...).

There are no elements that belong to both sets so the solution is the empty set. {∅}

Another way is to think about it in words: "What number(s) are less that 2 and also equal to to greater than 2?" Clearly there is no number that fits both of those.

3 A linear function is graphed below.7 (3,5)
X
(-1,-5)
What is the y-intercept of this graphed line?
PLEASE HELP!!!!!!

Answers

I believe the answer is b)-3.
The y-intercept is when a point passes through the y-axis. Hope this helps:)

Final answer:

To find the y-intercept of the given linear function, first, the slope of the function is calculated using the provided points. Then, the slope and one pair of coordinates are substituted into the y = mx + b equation to solve for 'b', which is the y-intercept.

Explanation:

In mathematics, specifically in the context of linear functions, the y-intercept is the point at which the line crosses the y-axis. From the provided points, however, it's not immediately clear what the y-intercept is.

To find the y-intercept, we need to determine the line's equation first. The equation of a line can be represented in the form y = mx + b, where 'm' is the slope of the line and 'b' is the y-intercept. To find the slope, we use the formula (y2 - y1) / (x2 - x1), substituting the given points. After calculating the slope, we can plug one pair of the given coordinates into the equation y = mx + b, and solve for 'b', which gives us the y-intercept.
