Answer:

Sal's Sandwich Shop sells wraps and sandwiches as part of its lunch specials. The profit on every sandwich is $2 and the profit on every wrap is $3. Sal made a profit of $1,470 from lunch specials last month. The equation 2x + 3y = 1,470 represents Sal's profits last month, where x is the number of sandwich lunch specials sold and y is the number of wrap lunch specials sold.

5. Suppose Sal's total profit on lunch specials for the next month is $1,593. The profit amounts are the same: $2 for each sandwich and $3 for each wrap. In a paragraph of at least three complete sentences, explain how the graphs of the functions for the two months are similar and how they are different.

6. Below is a graph that represents the total profits for a third month. Write the equation of the line that represents this graph. Show your work or explain how you determined the equations.

Karin's mom runs a dairy farm. Last year Betty the cow gave 375 litres less than twice the amount the amount from Bessie the cow

Oduvanchick [21]

Answer:

The volume of milk each cow produce are:

Betty = 851 litres

Bessie = 613 litres

Step-by-step explanation:

Let the volumes of milk from each of them be:

Betty = X litres

Bessie = Y litres

We are given the following information:

X = 2Y - 375 . . . . . . (1) (Betty the cow gave 375 litres less than twice the amount the amount from Bessie the cow)

X + Y = 1464 . . . . . . (2) (Together Betty and Bessie produced 1464 litres of milk)

Next, we will replace the value of 'X' in equation (2) with equation (1) as follows:

X = 2Y - 375 . . . . . . (1) ; X + Y = 1464 . . . . . . (2)

Therefore, equation (2) becomes:

(2Y - 375) + Y = 1464

2Y + Y - 375 = 1464

3Y - 375 = 1464

3Y = 1464 + 375 = 1,839 (divide both sides by 3)

∴ Y = 1839 ÷ 3 = 613 litres

Finally, from equation 2, we have X + Y = 1464 ; since Y = 613, solving for X:

X + Y = 1464

X + 613 = 1464

X = 1464 - 613 = 851 litres

Therefore:

Betty (X) = 851 litres

Bessie (Y) = 613 litres

Solve for the equation for the interval [0, 2pi). sec x/2 = cos x/2

Alenkinab [10]

Sec(x/2) = 1/cos(x/2)

sec(x/2)=cos(x/2) ----> cos^2(x/2)=1 ---> cos(x/2) = -1 and cos(x/2) = 1

Cos(x/2)=1 --- > x/2 = 0, only. x = 0;

cos(x/2)=-1 ----> x/2 = pi -> x = 2pi. But the statement says [0,2pi), so 2pi can not be chosen.

Only x = 0.

In fact, your equation is equivalent to sec(x)=cos(x), for x in [ 0, pi), so yes, only x = 0 .
