Let us assume the cost of a soft drink = x dollars
Value of the gift certificate that Angela had = $5
Cost of the movie ticket = $10
Cost of a medium popcorn = $5.50
Then
27.90 + 5 = 2(10) + 2(5.50) + x
32.90 = 20 + 11 + x
32.90 = 31 + x
x = 1.90 dollars

From the above deduction, it can be easily concluded that the correct option among all the options that are given in the question is the first option or $1.90.

I came in super late
Allushta [10]

Since we know that 1/4 is equal to 25%, or 0.25 in decimal form, we are able to work with 0.75 in the expression.


We are told to use j as the original price of the jeans, so we can set up the expression:


j-0.25j


to represent the cost of the jeans with the discount.


Then to simplify, we simply take out j as a common factor, and solve what's in the parentheses:


j(1-0.25)


j(0.75) or 0.75j


Using this equation, we can solve for the b part of the question. If the pair of jeans originally costs $60, plug in 60 to where j is in the expression:


0.75j

0.75(60)=45


Therefore, the cost of the jeans after the discount is C) $45.

How do you graph? <br> y=−4/3x+8y
trasher [3.6K]

How do we graph anything? Make a table of values for x and y and then plot each point. After plotting each point on the xy-plane, connect each point with a straight line or curve (depending on the function).


In this case, we must first isolate y.


y = (-4/3)x + 8y


y - 8y = (-4/3)x


-7y = (-4/3)x


y = (-4/3)x ÷ (-7)


y = (4/21)x


Now follow the steps above.

suppose you have 76 feet of fencing to enclose a rectangular dog pen. The function A=38x-x^2, where x= width, gives you the area
yan [13]
If A=38x-x^2 then

dA/dx=38-2x

d2A/dx2=-2

Since the acceleration, d2A/dx2 is a constant negative, when velocity, dA/dx=0, it will be an absolute maximum for A(x)

dA/dx=0 only when 38=2x, x=19

A(19)=38(19)-19^2

A(19)=722-361

A(19)=361 ft^2

So the maximum possible area is 361 ft^2

(This will always be true as the maximum possible area enclosed by a given amount of material will always be a perfect square...)
