In the algebraic expression 7/y why is coefficient of y? Explain.

Mathematics
1 answer:
dybincka [34]4 years ago
3 0

Answer:

7 is the (constant) coefficient of 1/y, but no, it is not the coefficient of y

Step-by-step explanation:

7/y can be rewritten as 7(1/y) or as 7(y^[-1]).  In this case, yes, 7 is the (constant) coefficient of 1/y, but no, it is not the coefficient of y.

Answer:

C =\frac{5}{9}(F - 32)

Step-by-step explanation:

Given

F = 1.8C + 32

Required

Solve for C

F = 1.8C + 32

Subtract 32 from both sides

F-32 = 1.8C + 32-32

F-32 = 1.8C

Divide both sides by 1.8

\frac{1}{1.8}(F - 32)  = C

Express the decimal as fraction

\frac{1}{18/10}(F - 32)  = C

\frac{10}{18}(F - 32)  = C

Simplify

\frac{5}{9}(F - 32)  = C

C =\frac{5}{9}(F - 32)

Does this graph show a function? Explain how you know.
DanielleElmas [232]

Answer:

yes

Yes; the graph passes the vertical line test.

Step-by-step explanation:

if it were a graph of a circle it would not pass

the vertical line test because the vertical line would touch at least 2 points

graph is probably a cubic function

something like

y = x^3-4x+6

What is the value of x?
gtnhenbr [62]
Value of x is used to consider unknown value. The letter “x” is commonly used in algebra to indicate an unknown value. It is referred to as a “variable” or, in some cases, a “unknown.” In x + 2 = 7, x is a variable

Does anyone else agree that the answer for this family of curves question is E, dy/dx = x + y?
neonofarm [45]
Yes this is the correct answer. The slope field shown is the differential equation dy/dx = x+y

All points along the line x+y = k, for some constant k, will have the same tangent slope k. For example, the line x+y = 0 will have every point with tangent slope 0 for the solution y(x). It may not be 100% clear, but this graph has horizontal tickmarks on the line x+y = 0, or the tickmarks are close to being horizontal. Using geogebra, I checked the others and they produced completely different graphs, which allowed me to rule them out.
