Answer:

answer : c    ( x = 1  , y = -1 , z = 1)

Step-by-step explanation:

put   x = 1  , y = -1 , z = 1

in this equations :

3(1)+3(-1)+6(1)=6 ........ 6=6 right

3(1)+2(-1)+4(1)=5 .....5=5  right

7(1)+3(-1)+3(1)=7......7=7  right

56 large boxes and 40 small boxes.

To solve this problem, we need to use the concept of multiples. By definition, a multiple of a number is that number multiplied by an integer. For instance, 3, 6, 9, 12 are multiples of 3. So let's do a chart and list the multiples of large and small boxes:

[tex]\begin{array}{cccccccccc}Number\,of\,boxes & 1 & 2 & 3 & 4 & 5 & 6 & 7 & 8 & 9\\Large & 8 & 16 & 24 & 32 & 40 & 48 & 56 & 64 & 72\\Small & 10 & 20 & 30 & 40 & 50 & 60 & 70 & 80 & 90\end{array}[/tex]

From this, our goal is to select the number of small and large boxes such that the sum is 96 boxes of hamburger burns and the number of large boxes is greater than the number of small boxes. From the table, the correct solution is:

56 large boxes and 40 small boxes, and this meets our requirement, because 56 + 40 = 96 and 56 > 40

3(x - 4) > 5x + 2

First you must distribute the 3 to the numbers inside the parentheses

(3 * x) + (3 * (-4)) > 5x + 2

3x + (-12) > 5x + 2

3x - 12 > 5x + 2

Now you must combine like terms

3x goes with 5x

^^^To do this subtract 3x to both sides of the equation

(3x - 3x) - 12 > (5x - 3x) + 2

0 - 12 > 2x + 2

-12 > 2x + 2

-12 goes with 2

^^^To do this subtract 2 to both sides

-12 - 2 > 2x + (2 - 2)

-14 > 2x + 0

-14 > 2x

Isolate x by dividing 2 to both sides

-14/2 > 2x/2

-7 > x

Hope this helped!

wednesday (9/11) has the most homework for Sarah. because it is equivalent to 90/110 which is greater than every other fraction answer given.

--mark brainliest please! thank you and i hope this helps

Sarah had the most homework on Wednesday.

The acronym LCM stands for the least common multiple or factor of any two or more specified integers. The least common multiple for the numbers 16 and 20 is 80, hence the LCM of those two numbers will be, for instance, 2 x 2 x 2 x 2 x 5 = 80.

Given

Sarah had the most homework on Wednesday. Least common multiple for 10, 5, 11 and 2 is 110.

Monday: 7/10 = (7*11)/(10*11) = 77/110

Tuesday: 3/5 = (3*22)/(5*22) = 66/110

Wednesday: 9/11 = (9*10)/(11*10) = 90/110

Thursday: 1/2 = (1*55)/(2*55) = 55/110

Since 90 > 77 > 66 > 55 it is clear that Sarah had the most homework on Wednesday.

Answer:

53 1/3 mph

Step-by-step explanation:

Speed equals distance over time.

She covered 300 miles in 60mph, which took 5 hours.

(300/60=5 )

She also covered 100 miles in 40mph, which means she took 2.5 hours.

(100/40=2.5)

So the total distance is 400miles and the total time is 7.5 hours.

s=d/t substitute values which gives you 400/7.5 which equals 53 1/3 mph

Answer: Option A and Option D

Step-by-step explanation:

By definition the general equation of a circle has the following form

[tex](x-h)^2+ (y-k)^2=r^2[/tex]

Where r is the radius and the point (h, k) is the center of the circle

All points that are on the x axis have the following form:

(h, 0)

Therefore all the circles that have their centers on the x axis will have a value of k = 0.

Identify among the options all those equations that have a value of k = 0

The circles that have their center on the x axis are option A and option D

Answer:

y = 5

Step-by-step explanation:

7(y + 2) – (4y – 10) = 44 – 2y + 5

(7y+14) - (4y - 10) = 49 -2y

3y +24 = 49 -2y

5y +24 = 49

5y = 25

y = 5

To solve the equation 7(y + 2) – (4y – 10) = 44 – 2y + 5, distribute and combine like terms to simplify both sides of the equation. Isolate the variable y on one side of the equation by performing inverse operations. The solution to the equation is y = 3.

To solve the equation 7(y + 2) – (4y – 10) = 44 – 2y + 5, we need to simplify both sides by distributing and combining like terms. Starting with the left side, we distribute 7 to both y and 2 to get 7y + 14. Then, distribute -1 to both 4y and -10 to get -4y + 10. Combining like terms, we have 7y + 14 - 4y + 10 = 44 - 2y + 5. Simplifying further gives us 3y + 24 = 39 - 2y. To isolate the variable y, we need to get all the y terms on one side. Adding 2y to both sides gives us 5y + 24 = 39. Finally, subtracting 24 from both sides yields 5y = 15. Dividing both sides by 5 gives us y = 3. Therefore, the solution to the equation is y = 3.

Answer:

x=1  y = -1/2

(1,-1/2)

Step-by-step explanation:

7x-2y=8  

5x+2y=4

I would use elimination since we have 2y in one equation and -2y in the other

7x-2y=8  

5x+2y=4

--------------------

12x = 12

Divide each side by 12

12x/12 = 12/12

x =1

The substitute back into equation 2

5(1) +2y = 4

5 +2y = 4

Subtract 5

5-5+2y = 4-5

2y = -1

Divide by 2

2y/2 = -1/2

y = -1/2

Answer:

The best method is the elimination method. The solution is (1, -1/2).

Step-by-step explanation:

7x - 2y = 8

5x + 2y = 4

12x = 12

x = 1

7(1) - 2y = 8

7 - 2y = 8

-2y = 1

y = -1/2

x =[tex]\frac{1}{8}[/tex]

Step-by-step explanation:

[tex]\frac{3}{8}-x=[tex]\frac{1}{4}[/tex]

⇒ Minus [tex]\frac{3}{8}[/tex] from both sides

- x =[tex]-\frac{1}{8}[/tex]

⇒ Multiply both sides by -1 to get rid of negative

x =[tex]\frac{1}{8}[/tex]

Answer:

x = 1/8.

Step-by-step explanation:

3/8 - x = 1/4

Subtract 3/8 from both sides:

- x = 1/4 - 3/8

-x = 2/8 - 3/8

-x = -1/8

Divide both sides by -1:

x = 1/8.

The length from one point on the edge of a circle to the middle will always be the same otherwise it isn't a circle. If QC is the same as CR than 15 and 15 would get you 30.

Answer:

70.686

Step-by-step explanation:

In order to know the length of QPR, we have to notice that QR=1/4 of the perimeter of the circle (circumference), then QPR= 3/4 of the perimeter of the circle.

Remember:

Circumference of a circle= 2[tex]\pi[/tex]*radius

Where:

[tex]\pi[/tex]= 3.1416 (its a constant value)

radius=15

Circumference of a circle=2*3.1416*15=94.248

Then:

QPR= 3/4 of the circumference of the circle

QPR= 3/4*94.248

QPR= 70.686

Answer:

78 points

Step-by-step explanation:

Let x = sum of the 10 scores

x/10 = 67

x /10 *10 = 67* 10 = 670

The sum of the 10 scores is 670

Now we play 1 more game and score g

We want to find the average  for the 11 games

The average is 68

(670 + g)/11 = 68

Multiply each side by 11

(670+g)/11 *11 = 68*11

670+g =748

Subtract 670 from each side

670+g-670 = 748-670

g =78

Answer:

[tex]f(x)=-\frac{1}{16} x^2[/tex]

Step-by-step explanation:

We are to derive the equation of the parabola with a focus at [tex](0, -4)[/tex] and a directrix of y = 4.

We know that a parabola is the locus of all the points as long as the distance from the fixed point on the parabola to the fixed line directrix is kept same.

This parabola is facing downwards. So assuming any point on the parabola to be [tex](x,y)[/tex].

Distance from focus [tex](0,-4)[/tex] to [tex](x,y)[/tex] = [tex]\sqrt{(x-0)^{2} +(y+4) ^{2}}=\sqrt{x^{2}+ (y+4)^{2}}[/tex]

Distance from [tex](x,y)[/tex] to directrix [tex](y=4)[/tex] = [tex]\left | y-4 \right |[/tex]

Equating these distances as they are equal:

[tex]\sqrt{x^{2}+ (y+4)^{2}}=\left | y-4 \right |[/tex]

[tex]{x^{2}+ (y+4)^{2}=(y-4)^{2}[/tex]

[tex]x^2+y^2+8 y +16 = y^2 - 8 y+16[/tex]

[tex]x^2 = -8 y - 8 y= -16 y[/tex]

[tex]x^2= - 16 y[/tex]

So the equation of the parabola is [tex]f(x)=-\frac{1}{16} x^2[/tex].

Answer:

The equation of the parabola is y = -1/16 x²

Step-by-step explanation:

* Lets revise some facts about the parabola

- Standard form equation for a parabola of vertex at (0 , 0)  

- If the equation is in the form  x² =  4py, then  

- The axis of symmetry is the y-axis,  x = 0  

- 4p equal to the coefficient of y in the given equation to  

  solve for  p  

- If  p  >  0, the parabola opens up.  

- If  p <  0, the parabola opens down.

- Use p to find the coordinates of the focus,  (0 , p)

- Use p to find equation of the directrix ,  y = - p

* Lets solve the problem

∵ The focus at (0 , -4)

∵ The coordinates of the focus are (0 , p)

∴ p = -4

∵ The directrix is y = 4

∵ The equation of the directrix ,  y = - p

∴ -p = 4 ⇒ p = -4

∵ the equation is in the form  x² =  4py

∵ p = -4

∴ x² = 4(-4)y

∴ x² = -16y ⇒ divide both sides by -16

∴ y = -1/16 x²

* The equation of the parabola is y = -1/16 x²
