Jason spent a total of $131 on shirts. Dress shirts cost $28 dollars and T-shirts cost $15 dollars. If he brought 7 shirts how many of each kind did he buy?

Answers

Answer:  28x  + 15y = 131   and x + y =  7   where x is the number of Dress shirt and y is the number of T-shirt.

Step-by-step explanation:

We will represent the number of Dress shirt he bought by x and we will represent the number of T-shirt he bought by y.

We know that he spent 131 so the cost of each dress shirt plus the cost of each T-shirt has to equal  131.  Also, he bought 7 total shirts so x plus y has to equal 7.

28x  + 15y = 131  

x + y =  7

Note: it says don't solve so I didn't solve but if you want to solve use these equations.

Answers

Degrees measure D. incline

The degrees measure the incline because the degree measures an angle which is the measure of incline option (D) is correct.

What is an angle?

When two lines or rays converge at the same point, the measurement between them is called an "Angle."

It is given that:

The measuring unit is the degree

The measurement can be defined as the numerical quantity that gives an idea about object length, width, and many more. It can be used to compare two objects.

As we know from the definition of the angle; two lines or rays converge at the same point, and the measurement between them is called an "Angle."

The degree measures an angle which is the measure of incline.

Thus, the degrees measure the incline because the degree measures an angle which is the measure of incline option (D) is correct.

If f(x) and r1(x) are inverse functions of each other and f(x)=2x+5 , what is f^-1(8) ?

PLEASE HELP!!

Answers

Answer:

3/2

Step-by-step explanation:

Given y = 2x + 5, let's rewrite the equation in terms of x;

y = 2x + 5 => Bring 5 to the other side

2x = y - 5 => Divide either side by 2

x = (y - 5)/2

If we want to take the inverse, simply swap the variable's positions...

We have y = (x - 5)/2

Now let's determine f^-1(8), substituting for "y" provided y is our inverse, f^-1

f^-1(8) = (8 - 5)/2 = 3/2

Solution: 3/2

I also understand that you have identified six finalists who are highly qualified for the position, three of whom are deaf. I have a deep interest in disability civil rights. Over the past few years I have worked with many national and local organizations run by and for disabled people, including the National Council on Independent Living, the National Council on the Handicapped, Capitol People First of Sacramento and the Association on Handicapped Student Service Programs in Post-Secondary Education. I have also had many conversations with disabled leaders, including deaf persons, throughout the United States. And my office has served as the focal point for the development of the Administrations disability policy. From this experience, I have become aware of the two basic principles underlying the disability rights movement; the right of disabled people to control their own lives and the right to integration and involvement in society. Gallaudet University has a critical role to play in advancing these principles. It is held in the highest regard by deaf people throughout the United States and the world. It provides an excellent education and a meaningful future for thousands of deaf persons. More importantly, Gallaudet University is a symbol of leadership and opportunity, not only for deaf people, but for all of us. In the last two decades our society has undergone a quiet revolution. The Congress, the Courts and the Administration have strongly supported the right of people with disabilities to hold positions of trust and leadership. Our government has enacted numerous laws to ensure that disabled people are ensured equality of opportunity. Accordingly, as an entity funded by the Federal government, Gallaudet has a responsibility to set an example and thus to appoint a President who is not only highly qualified, but who is also deaf. I hope that the Trustees will keep Gallaudets critical leadership position in mind when they make their decision.
