Answer:
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one.
<em>Yolanda does a weekly exercise program consisting of cardiovascular work and weight training. Each week, she exercises for at least 6 hours. She spends at most 11 hours doing cardiovascular work. She spends at most 4 hours on weight training. Let x denote the time (in hours) that Yolanda spends doing cardiovascular work. Let denote the time (in hours) that she spends on weight training. Shade the region corresponding to all values of x and y that satisfy these requirements.</em>
Here is my answer:
Let x is the hours of doing cardiovascular work
Let y is the hours of doing weight training
Given that :
- Each week, she exercises for at least 6 hours.
<=> x + y ≥ 6 (1)
- She spends at most 11 hours doing cardiovascular work.
<=> x ≤11 (2)
- She spends at most 4 hours on weight training
<=> y ≤ 4 (2)
- Note that times x and y are always no less than 0, so
x ≥0 (3)
y≥0 (4)
After that, we have the system of of inequalities (1) (2) (3) (4)
Please have a look at the attached photo, This diagram shows the triangle with vertices that is the solution set (triangle and all points inside triangle)
Hi there!
First replace m(x) by y.
To find the inverse function we must switch the places from the variables x and y.
Now we need to isolate the y again to find the formula of the inverse function. First add 5 to both sides.
Switch sides.
And finally divide both sides by 5.
And therefore we can conclude the following:
The answer is C.

Answer:
d
Step-by-step explanation:
rearrange it like an equation.
take everything else out of the middle apart from x.
make sure that what you do to the middle you do to both sides
Answer:
x = 90
Step-by-step explanation:
First, you'll want to take the three equations you see and set them up in an addition equation to add up to 360 like so...
- 4x + 2y + x + 2y - x = 360
Since two opposites add up to zero, they can be removed from the equation, therefore, removing (+ x) and (- x) from this equation:
Collect like terms (2y and + 2y):
Move the variable (+ 4y) to the right hand side of the equation and change its sign:
Divide both sides of the equation by 4.
x = 90 - y
Ignore the i y and you got your answer. x = 90. Hope this helped!
