X +y=3 and 2x +3y=-4

Answers

Answer:

x + y = 3

2x + 3y = 4

Solve equation for the variable y

y = -x + 3

Plug this in for variable y in equation

2x + 3•(-x +3) = 4

-x = -5

Solve equation for the variable x

x = 5

By now we know this much :

x = 5

y = -x+3

Use the x value to solve for y

y = -(5)+3 = -2

Compare the roles of the endoplasmic reticulum and Golgi apparatus.

Answers

Answer:

The endoplasmic reticulum is the three-dimensional membrane that runs through the cytoplasm and it also presents attached with the plasma membrane, nuclear envelope, and Golgi complex whereas the Golgi apparatus is made up of cisternae which is flat and expanded made up of protoplasm. The role of both endoplasmic reticulum and Golgi apparatus are related to each other. In the cell wall, the endoplasmic reticulum provides a skeletal framework to the cell which helps to give support to the cytoplasmic matrix whereas the Golgi apparatus synthesizes pectic compounds and polysaccharides which help in the formation of the cell wall. The protein which gets synthesized by rough endoplasmic reticulum is passed on Golgi apparatus, the cisternae of Golgi apparatus help to combine the protein with carbohydrate and form glycoprotein. The endoplasmic reticulum provides enzyme precursors to the Golgi apparatus which get packed in the vesicles of the Golgi apparatus and later after budding primary lysosomes get formed by the maturing face of cisternae.

what's the value if m

2m^2-m-3

Answers

Answer:

m = 1/2

m = -1

Explanation:

Step 1  - Let y=0.

2m^2-m-3 = 0

Step 2 - Factor

(2m  - 3 )( m   +      1 ) = 0      

Step 3  

2m-1 = 0                m +1 = 0

Step 4 - Solve

2m = 1 (divide 2 on both sides)        m+1 = 0 (subtract 1 on both sides)

m = 1/2                                                 m = -1

If a person qualifies, why is it better to accept a subsidized loan before an unsubsidized loan?

Answers

If a person qualifies, it is better to accept a subsidized loan before an unsubsidized loan because "a subsidized loan has lesser interest charges."

Though a subsidized loan is only available to specific people, such as undergraduate students, the interest rates remain the same throughout college years.

This is because the United States Department of Education helps cover the interest that should accrue over time.

Subsidized loans are also available to the post-baccalaureate teacher certification program and orphans of parents killed in Iraq and Afghanistan after the 9/11 incident.

Hence, in this case, it is concluded that a Subsidized loan has many advantages for those that qualify.
