Which of the following problems would NOT have a solution?
o Eight pizzas are shared equally among four people, and you want to know how
much each person gets.
o Four pizzas are shared equally among three people, and you want to know how
much each person gets.
o Zero pizzas are shared equally among four people, and you want to know how
much each person gets.
o Three pizzas are shared equally among zero people, and you want to know how
much each person gets.

Answers

Answer:

  (d)  Three pizzas are shared equally among zero people, and you want to know how much each person gets.

Step-by-step explanation:

You want to know which pizza sharing problem has no solution for the amount each person gets:

8 pizzas, 4 people4 pizzas, 3 people0 pizzas, 4 people3 pizzas, 0 people

Pizza per person

The amount of pizza each person gets is found by dividing the number of pizzas by the number of people:

8 pizzas/(4 people) = 2 pizzas per person4 pizzas/(3 people) = 4/3 pizza per person0 pizzas/(4 people) = 0 pizzas per person3 pizzas/(0 people) = undefined — no solution

The problem of dividing 3 pizzas among 0 people has no solution.

Taking like terms ( i.e. terms with same variables ) to left side and constant terms ( i.e. simple numbers ) to right side . .

[tex]⇢7x - x - 2x = 26 + 10[/tex]

[tex]⇢6x - 2x = 36[/tex]

[tex]⇢4x = 36[/tex]

[tex]⇢x = \frac{36}{4} [/tex]

[tex]⇢ \boxed{x = 9}[/tex]

Answer:

x = 9

Step-by-step explanation:

#1) Simplify each side.

7x - 10 - x = 2x + 266x - 10 = 2x + 26

#2) Bring x terms to the left side and numbers to the other side.

6x - 2x = 26 + 104x = 36

#3) Divide both sides by 4.

4x/4 = 36/4x = 9

cat is 50º. About how far from the wall is the dog?

Answers

Answer:

5.0344

Step-by-step explanation:

tan=opposite

      adjacent

Since you're trying to find the adjacent side to the angle 50, use tan.

So tan 50º= 6/x

Swap x and tan 50º , which puts tan 50º under the 6.

Use your calculator to find the approximate value of tan 50º (rounded to 4 decimals)

Then divide!

Find the area of the shape shown below. ​ ​

Answers

Answer:

12 cm²

Step-by-step explanation:

Area of triangle: bh/2 = (2)(3)/2 = 3

Area of square: bh = (2)(3) = 6

Total area of the shape = 2 triangles + 1 square

Total area = 2(3) + 6 = 12 cm²

I hope this helps!

Answer:

12

Step-by-step explanation:

You can find the area of the shape 2 different ways.

I'll show you both ways.

First Way: find the area of each individual shape that makes it up then add them together

We can find the area by finding the area of the rectangle and then the two triangles and then adding the two multiples together

Area of a rectangle = length × width

Length = 3 and width = 2

So area = 3 × 2 = 6

Now to find the area of the triangles

Area of a triangle = 1/2bh

Where b = base length and h = height

The base length is 2 and the height is 3

So area = 1/2 × 2 × 3 = 3

There are two triangles and they both have the same dimensions

So the area of both triangles = 2 × 3 = 6

Finally we add the areas together to get the total area

Total Area = 6 + 6 = 12cm²

Second way : Use the area of a trapezoid formula:

The shape shown is a trapezoid so we could also use the area of a trapezoid formula.

Formula : [tex]A=\frac{a+b}{2} h[/tex]

where a and b = base lengths and h = height

The base lengths appear to be 2 and 6 and the height is 3

So a = 2 , b = 6 and h = 3

Which means [tex]A=\frac{2+6}{2} 3[/tex]

Simplify addition

[tex]A=\frac{8}{2} 3[/tex]

simplify division

A = (4)3

Then multiply
A = 12cm²

     A straight line has a measurement of 180° so these two angles added together will equal 180°.

     (10x - 20)° + (6x + 8)° = 180°

     10x° + 6x° + 8° - 20° = 180°

     16x° -12° = 180°

     16x° = 192°

     x = 12

Which inequality is shown in this graph?
6
5
(-2, 2)
-5
5
(0, -2)

Answers

The inequality of the graph is a linear inequality

The inequality shown in the graph is y > -2x -2

How to determine the inequality?

The points on the graph are given as:

(x,y) = (-2,2) and (0,-2)

The slope (m) is calculatedusing:

m = (y2 - y1)/(x2 - x1)

This gives

m =(-2 - 2)/(0 + 2)

Evaluate

m = -2

The equation is then calculated as:

y = m(x - x1) + y1

This gives

y = -2(x - 0) -2

y = -2x -2

The upper part of the graph is shaded with a dotted line, so the inequality is a greater than inequality

The equation becomes

y > -2x -2

Hence, the inequality shown in the graph is y > -2x -2

Graphing f(x)=(x+2)^2-3 in vertex form

Answers

Answer:

Step-by-step explanation:

This is a parabola shaped like a U.

The minimum value is at (-2, -3).

Find the zeroes:

(x + 2)^2 = 3

Find the zeroes:

x + 2 = +/- √3

x = +/-√3 - 2

x = -0.27, -3.73.

So the graph cuts the x axis at (-0.27, 0)  and (-3.73, 0)

when x = -4 , f(x) = 1 and when x = 1,  f(x) =  6.

So you can now draw the curve through these 5 points and it will be shaped like a U, symetrical about the line x = -2

Step-by-step explanation:

The length of the rectangle:

The width of the rectangle is x. If you add the two widths together when finding perimeter, x + x, that would give you 2x.

Sum of widths: x + x = 2x

Use the sum of the widths to find the sum of the lengths by subtracting from the perimeter.

sum of lengths = perimeter - sum of widths

8x - 2x = 6x

Since there are 2 lengths divide by 2.

6x/2 = 3x

The length of the rectangle is 3x

Perimeter of the square:

The sides of the square are 1/4 of the length of the rectangle. "of" means to mulitply: (I made 3x a fraction by placing it over 1)

[tex]\frac{1}{4} (\frac{3x}{1} )[/tex] = [tex]\frac{3}{4} x[/tex]

Now find the perimeter of the square by multiplying the side length by 4.

[tex]\frac{3}{4}x(\frac{4}{1} )[/tex] = [tex]3x[/tex]

Last part:

solve the rectangle's perimeter by substituting x with 4.

P = 8x

P = 8(4)

P = 32 cm

Solve the square's perimeter by substituting x with 4.

P = 3x

P = 3(4)

P = 12 cm

Divide the rectangle's perimeter by the square's perimeter.

32/12 = 2 2/3 times bigger.

False, it would actually be 106 beads. If this was a multiplication problem, that would also be false, because 6 times 100 is 600, not 350.

how do i find a,b and k?​

Answers

Answer:

a = 1

b = 2

k = -2

Step-by-step explanation:

Given:

[tex]\displaystyle \large{y=k(x-a)^2(x-b)}[/tex]

First, find the a-value and b-value by observing the graph. Notice that once the graph hits x = 1, it just goes up or concave up - that indicates to be the double roots of function. Therefore:

Our a-value is 1

Second, find the b-value. Another x-intercept beside double roots x = 1 is x = 2 as shown in the graph. Therefore:

Our b-value is 2

Third, find the k-value. Right now we have the equation:

[tex]\displaystyle \large{y=k(x-1)^2(x-2)}[/tex]

To find the k-value, simply find a point’s value (x,y) to substitute. According to the graph, you can try substitute (0,4) in:

[tex]\displaystyle \large{4=k(0-1)^2(0-2)}\\\displaystyle \large{4=k(-1)^2(-2)}\\\displaystyle \large{4=k(1)(-2)}\\\displaystyle \large{4=-2k}\\\displaystyle \large{k=-2}[/tex]

find the x and y intercepts of the linear equation 2x - 4y = -20

Answers

Answer:

Step-by-step explanation:

We are given the following equation of a line:

To determine the x-intercept we must set "y = 0":

[tex]2x-4(0)=-20[/tex]

[tex]2x=-20[/tex]

Now, we divide both sides by 2:

[tex]x=-\frac{20}{2}=-10[/tex]

Therefore, the "x" intercept is -10.

To determine the y-intercept we set "x = 0":

[tex]2(0)-4y=-20[/tex]

[tex]-4y=-20[/tex]

Now, we divide both sides by -4:

[tex]y=\frac{-20}{-4}=5[/tex]

Therefore the y-intercept is 5.
