Which of the following equations represents that “ x decreased by 28%” is the same as “the product of 0.72 and x”? A) x + 0.28x = 0.72x

B) x – 0.28x = 0.72 x

C) x + 0.28x = 0.72 x

D) x – 0.28x = 0.72x

rectangle: 9 1/8 x 4 1/9 = 37 37/72in

parallelogram: b times h= 10.3 x 6.2 = 63.86

trapezoid: a+b/2 times h= 42.5

volume of prism: l times w times h= 36

you should pay $0.88

what is the image?

$450

step-by-step explanation:

first, you have to multiply 150x2=300

next, you have to add 150+300= 450

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
