Part A: write 2 1/4 as a decimal and a percent. Part B: write 4 as a fraction and a percent. Part C: Write 75% as a fraction and a decimal. Part D: Put these three numbers in order from least to greatest.

(A)  2 1/4 as a decimal is 2.25

(B)  4 s a fraction is 4/1 and as a percent it is 400%

(C)  75% as a fraction is 3/4 and as a decimal it is 0.75

(D)  least to greatest is 4, 2 1/4, 75%

Step-by-step explanation:

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
