A test has twenty questions worth 100 points. The test consists of True/False questions worth 3 points each and multiple choice

questions worth 11 points each. This system of equations can be used to find how much of each question type he has.
x + y = 20
3x + 11y = 100

"X" represents the number of true/false question and "y" represents the multiple choice questions.
The solution to the system is (15, 5). What is the correct interpretation of this solution.

What od linear algebra exactly?
Alex73 [517]

Answer:

Linear algebra is the study of lines and planes, vector spaces and mappings that are required for linear transforms. It is a relatively young field of study, having initially been formalized in the 1800s in order to find unknowns in systems of linear equations.

In circle P, EG and FH are diameters.<br> What is m EH?
zvonat [6]

Answer:

m(\widehat{EH}) = 130°

Step-by-step explanation:

Angles subtended at the center by the arcs (\widehat{HG}) and (\widehat{EF}) are ∠HPG and  ∠EPF.

Since these angles are the vertical angles both will be equal.

m∠HPG ≅ m∠EPF

3x - 10 = 2x + 10

3x - 2x = 10 + 10

x = 20

Therefore, m(\widehat{HG})=(3\times 20) - 10

                               = 50°

Similarly m(\widehat{EF}) = 50°

In the same way angles subtended at the center will be equal.

m∠EPH ≅ m∠FPG

and m(\widehat{EH})=m(\widehat{FG})

Since m(\widehat{EH})+m(\widehat{FG})+m(\widehat{EF})+m(\widehat{HG})=360°

m(\widehat{EH})+m(\widehat{EH})+50+50=360

2m(\widehat{EH})=360-100

m(\widehat{EH})=130

Therefore, measure of arc EH = 130°

What is the slope–intercept form of the equation 4x − 2y = 9?
adelina 88 [10]
Hey there! :D

Slope intercept form: y=mx+b

4x-2y=9

Add 2y to the other side. 

4x=9+2y

Subtract 9 on both sides.

4x-9=2y

Flip the equation over. 

2y=4x-9 <== slope intercept form 

I hope this helps!
