Can someone show me how to do this one correctly?

Leah, this is the solution:

Variables:

Let x to represent the weight of one Hershey kiss

Let y to represent the weight of one Reese cup

System of equations:

6x + 6y = 82.4

4x + 5y = 63.8

______________

Let's multiply the second equation by - 3/2, therefore:

6x + 6y = 82.4

-6x - 15y/2 = -95.7

________________

-15/2 + 6 = -3/2

_________________

-3y/2 = -13.3

Dividing by -3/2 at both sides:

-3y/2 / -3/2 = -13.3 / -3/2

y = 8.87

______________

Replacing y in the first equation and solving for x:

6x + 6 * 8.87 = 82.4

6x + 53.22 = 82.4

Subtracting 53.22 at both sides:

6x +53.22 - 53.22= 82.4 - 53.22

6x = 29.18

Dividing by 6 at both sides:

6x/6 = 29.18/6

x = 4.86

_________________

In conclusion, one Hershey kiss weights 4.86 ounces and one Reese cup weights 8.87 ounces.

Length of the entire rectangle = 12 + 5 = 17

Width of the entire rectangle = 6+4 = 10

Part a

Area of rectangle = Length x width

Area of the entire rectangle = 17 x 10 = 170 square units

Part b

Perimeter of rectangle = 2( length + width )

Perimeter of the entire rectangle = 2(17 + 10 )

=2 (27) = 54

Perimeter of the entire rectangle = 54 units

Length of the entire rectangle = 12 + 5 = 17

Width of the entire rectangle = 6+4 = 10

Part a

Area of rectangle = Length x width

Area of the entire rectangle = 17 x 10 = 170 square units

Part b

Perimeter of rectangle = 2( length + width )

Perimeter of the entire rectangle = 2(17 + 10 )

=2 (27) = 54

Perimeter of the entire rectangle = 54 units

Solution

We have the following function given:

f(x) = -3x+5

And we need to do the following:

5= -3x+5

17) f(-2)= 3

18) f(0)= 3

19) f(1)= 0

20) f(-1)= 5.2

step 1

The equation of line k is y=-x

The rule of the reflection across the line y=-x is equal to

(x,y) -------> (-y,-x)

so

we have the point (2,5)

Apply the rule

(2,5) -----> (-5,-2)

step 2

Reflection across the x axis

The rule of the reflection across the x axis is

(x,y) ------> (x,-y)

so

Apply the rule to the point (-5,-2)

(-5,-2) ------> (-5,2)

therefore

the answer is

Given:

So:

Then two sides are also equal.

So the value of x is 6.

The surface area of a sphere is given by

in our case r=10 units ( the radius). By substituting this value into the last formula, we have

which gives

On the other hand, the surface area of a cube is given by

where L is the length of one side, that is, L=10. Then, we have

By comparing both results, we can see that the surface area of our sphere is larger than the surface area of the given cube. So the answer is TRUE.

Answer

(x - 2)² + (y - 2)² = 8

Step-by-step explanation

The equation of the circle centered at (h, k) with radius r is:

In this case, the center of the circle is the point (2, 2), then h = 2 and k = 2, that is,

Given that the circle passes through the center, then the point (0, 0) satisfies the above equation. Substituting x = 0 and y = 0 into the equation and solving for r²:

Substituting r² = 8 into the equations, we get:

Principal amount, P= $290.

Rate, r = 0.076

Time, t = 2

Therefore, the total amount in her account after 2 years is

Hence,

Therefore, the amount is 335.80 dollars.

That is, 335 dollars and 80 cents.

It is given that the function is:

Therefore y=0 then the value of x will be:

Now at x=0, y will be:

at x=1, y will be:

These 3 points that is (-inf,0),(0,3/4),(1,3) are on graph D.

Hence option D is coreect.

Given the functions:

You need to multiply them, in order to find:

Then, you get:

In order to find the Domain, you need to remember that the Domain of a Radical Function are those input values (x-values) for which the Radicand is positive. Then, in this case, you need to set up that:

Now you have to solve for "x":

Therefore:

Hence, the answer is:

In order to determine the amount of brownies left in the refrigerator, subtract 8 from 12.

If Abby bakes 2 -dozen brownies, she baked 24 brownies. There are 12 pieces in 1 dozen, thus if she bakes two dozens, she baked 24 brownies ( 12 x 2).

The amount of brownies left after she takes one dozen to school = amount baked - amount taken for the meeting

24 - 12 = 12

Amount left in the refrigerator : amount left after she took a dozen for the meeting - amount eaten by her family

12 - 8 = 4

so the distance between them is the square root of 13.

The hours when the prices of the two stocks be the same is 2.38 hours.

From the information, the price of Stock A at 9 A.M. was $12.42 and the price has been increasing at the rate of $0.12 each hour. This will be the expressed as 12.42 + 0.12h.

At noon the price of Stock B was $12.92. It begins to decrease at the rate of $0.09 each hour. This will be:

= 12.92 - 0.09h

where h = number of hours

Equate both equations. This will be:

12.42 + 0.12h = 12.92 - 0.09h

Collect like terms

12.92 - 12.42 = 0.12h + 0.09h

0.21h = 0.50

h = 0.50 / 0.21

h = 2.38 hours.

WE are to solve an inequality, so we proceed to isolate the variable "p" on one side of the inequality symbol:

6 p - 15 < 33

we add 15 to both sides:

6 p < 33 + 15

6 p < 48

now divide both sides by 6 (notice that since 6 is a positive number, the division doesn't change the direction of the inequality)

p < 48/6

p < 8

So we need to highlight on the number line, the line that starts at "8" and goes all the way to the left (to minus infinity), and make sure that at the point "8" you draw an "empty" circle to indicate that the number 8 itself is NOT included in your set of solutions.
