PLS HELP!!! due to inflation nominal prices are usually there were to demand increases. After the second increase the price for
SashulF [63]

Answer:

The first increase was of 60%.

Step-by-step explanation:

The initial value of the product is x.

The first increase was of y.

The second increase is of 25%, that is, 1.25.

The final price was double the original, so 2x.

This situation can be modeled by the following equation:

xy(1.25) = 2x

We want to find y.

Simplifying by x

1.25y = 2

y = \frac{2}{1.25}

y = 1.6

After the first increase, the value was 1.6 of the original value, that is a increase as a percent of (1.6 - 1)*100 = 60%.

What is the slope of 6x+10y=8<br> (choice A)<br> A -3/4<br><br> B -5/4<br><br> C -3/5<br><br> D -4/5
kvv77 [185]

Answer:

C

Step-by-step explanation:

The equation of a line in slope- intercept form is

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

Rearrange 6x + 10y = 8 into this form by subtracting 6x from both sides

10y = - 6x + 8 ( divide all terms by 10 )

y = - \frac{3}{5} x + \frac{4}{5} ← in slope- intercept form

with slope m = - \frac{3}{5} → C

Four students were asked to write an expression which has terms that have a greatest common factor of 8c. The expressions
Olin [163]

Answer:

<h2>Wyatt</h2>

Step-by-step explanation:

Greatest common factor is a largest possible number or function that divides all values of a function without a remainder. According to the students, only Wyatt wrote the correct expression that has 8c as its greatest common factor.

According to Wyatt expression;

8c-48cd

It can be seen that 8c is the greatest function that can go in both monomials (8c and 48cd). On factoring out 8c we have;

8c-48cd = 8c(1-6d)

since no other values can go in the values in parenthesis (1-6d), this shows that 8c is the greatest common factor of the function hence only Wyatt wrote the correct expression compare to other students.

According to Xavier and Yang equation, c is cannot be factored from the equation thereby making both the wrong expression.

For Tanya function 32c+16cd, its greatest common factor is 16c not 8d making the equation wrong as well.

Like terms can be combined.

  (8x +16) +(7x -9) = (8x +7x) +(16 -9) = 15x +7

The total number of ice cream cones sold was 15x+7.
