Big Y has rice on sale for $1.99 per bag. You bought one bag of rice and 6 cans of black beans. Your total cost was $7.33. How m

Papessa [141]

Answer:

$0.89

Step-by-step explanation:

so one bag is 1.99

her total cost was 7.33

you bought 6 cans of BB

so you do 7.33 minus 1.99

5.34 divided by 6

Use the table from Callie's Candies to answer the question.

frez [133]

We can use logic along with 3 linear equations to solve this problem.

For the three types of candies, we will write a slope-intercept form equation. We know what m (slope) is for each equation, and there is no y-intercept because there is no starting point.

Equations:

Mints: y=.96x
Chocolates: y=4.70x
Lollipops: y=.07x

Using the given information, we can use the equations in function form. We know what x (input) is for all three types of candy, and that will give us y (output), which is the total for that candy type.

Solving:

Mints: y=.96(.75)
Chocolates: y=4.70(1.5)
Lollipops: y=.07(15)
We just input our information into the equations. Using logic, we know that we will have to multiply the cost of the candy by the number of candies to get the total of the three types.

Totals:

Mints: y=.72
Chocolates: y=7.05
Lollipops: y=1.05.
*Recall that y=total cost of candy for each type.

Now, we just simply add the three costs up to get the total sum that the candy will cost:

.72+7.05+1.05=8.82

Therefore, all the candy will cost $8.82.

The functions f(x) = -(x+4) +2 and g(x) =(x-2)^2 -2 have been rewritten using the completing the square method. Apply your knowl

rewona [7]

Answer:

$g(x) = (x-2)^2 -2$

If we compare this function with the vertex form we see that:

$a = 1, h =2, k =-2$

So then the vertex would be $(h,k)=(2,-2)$

And since the value for a is positive we know that the parabola open upward. We don't have a maximum defined since open upwards and the minimum point correspond to the vertex on this case (2,-2).

$f(x)= -(x+4)^2 +2$

If we compare this function with the vertex form we see that:

$a=-1, h =-4, k = 2$

And since the value for a is negative we know that the parabola open downward. We don't have a minimum defined since open downwards and the maximum point correspond to the vertex on this case (-4,2).

Step-by-step explanation:

We need to remember that the standard form for a parabola is given by the following equation:

$y = ax^2 + bx +c$

And the vertex form is given by this formula:

$y = a(x-h)^2 +k$

And we want to find the vertex and if we have a maximum or minimum for each function. Let's begin with g(x)

$g(x) = (x-2)^2 -2$

If we compare this function with the vertex form we see that:

$a = 1, h =2, k =-2$

So then the vertex would be $(h,k)=(2,-2)$

And since the value for a is positive we know that the parabola open upward. We don't have a maximum defined since open upwards and the minimum point correspond to the vertex on this case (2,-2).

For the function f(x) we assume that we have the following equation:

$f(x)= -(x+4)^2 +2$

If we compare this function with the vertex form we see that:

$a=-1, h =-4, k = 2$

And since the value for a is negative we know that the parabola open downward. We don't have a minimum defined since open downwards and the maximum point correspond to the vertex on this case (-4,2).
