Directly proportional to x.

<h3>What is propotionality?</h3>

In algebra, proportionality is the equality of two ratios.
A and B are in the same ratio as C and D in the formula a/b = c/d.
When one of a proportion's four quantities is unknown, a proportion is often built up to resolve the word problem.
By multiplying one numerator by the opposing denominator and equating the result to that of the other numerator and denominator, the equation can be solved.
Any relationship that has a constant ratio is said to be proportionate. For instance, the ratio of proportionality is the average number of apples per tree, and the amount of apples in a crop is proportional to the number of trees in the orchard.

Acc to our question-

If two variables' ratios (yx)
(x and y) have the same value as a constant (k=yx)
therefore the ratio's variable (y) in the numerator is the sum of the other variable and the constant (y=k:x).
With a proportionality constant of k, it is claimed that y is directly proportional to x in this instance.

Hence,Directly proportional to x.

Please help don't understand

-1.5(4-n)+2.8

multiply 4-n by -1.5
multiply to both the 4 and -n

-6+1.5n+2.8

add -6+2.8 since they are similar

-3.2+1.5n

1.5n-3.2

I believe this is the simplest form

In attempting to solve the system of equations and , John graphed the two equations on his graphing calculator. Because he saw o

Answer:

The correct answer is NO.

Step-by-step explanation:

John is graphing two lines with equations say ax + by + c = 0 and dx + ey +f =0 on his graphing calculator.

For John to get a unique solution the coefficients should follow the following condition $\frac{a}{d} \neq \frac{b}{e}$ . So when he plots the lines he get an intersecting pair of lines.

For John to get no solution the coefficients should follow the following condition $\frac{a}{d} = \frac{b}{e} \neq \frac{c}{f}$ . When we plot in this case we get two parallel lines.

For John to get an infinite many solution the coefficients should follow the following condition $\frac{a}{d} = \frac{b}{e} = \frac{c}{f}$ . And when we plot the lines in this case we get one line superimposed on the other.
