What is the range of the function graphed on the grid

Answer:

Isn't this an AoPS Problem?

Step-by-step explanation:

Answer:

False

Step-by-step explanation:

If you divide both sides of the equation by (x+3), you get (x-3)=(x-8)

That makes 3 = 8.

The only way this is possible is if x = -3

Answer:

False

See picture for steps

Area formula: a = l * w

a = 8 * 4.5

a = 36

Perimeter formula: p = 2l * 2w

p = 2(8) + 2(4.5)

p = 16 + 9

p = 25

Best of Luck!

Answer:

it is 0

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

both A and B are false, because no value would allow Sari to pay Raymond and then still have 30 dollars so it has to be C or D

42 - 24 = 18                18 times 3 is 54, so this appears to work

30 + 24 = 54

42 - 18 = 24       24 times 3 is not 48, so C is incorrect

30 + 18 = 48

Answer:

Final answer:

To determine the number of solutions for the system of equations 2x+8y=16 and -3x+6y=30, the elimination method can be used. After multiplying and combining the equations, it is found that the system has a unique solution at (-4, 3). This means the two lines intersect at exactly one point.

Explanation:

The student is asking about the number of solutions for the system of equations 2x+8y=16 and -3x+6y=30. To find out how many solutions the system has, we can use either substitution, elimination, or graphing methods. Substitution involves solving one equation for one variable and then substituting that into the other equation. Elimination involves adding or subtracting equations to cancel out one of the variables, which can be followed by solving for the remaining variable. Graphing would involve plotting both equations and observing their intersection points.

For this specific problem:

Equation 1: 2x+8y=16

Equation 2: -3x+6y=30

If we try to use the elimination method, multiplying Equation 1 by 3 and Equation 2 by 2 would allow us to cancel out the x's:

Multiplying Equation 1 by 3: 6x+24y=48

Multiplying Equation 2 by 2: -6x+12y=60

Adding these equations together gives us:

36y=108, which simplifies to y=3. Substituting y=3 into Equation 1, we can solve for x:

2x+8(3)=16

2x+24=16

2x=-8

x=-4

Thus, the system has a unique solution (x, y)=(-4, 3), indicating that the two lines intersect at exactly one point.

Answer:

los dos son lo mismo solo que se multiplican por dos espero me entiendas

Step-by-step explanation:

Answer: They equal the same thing

Step-by-step explanation: Notice that the fractions that we're comparing in this problem have different denominators. When fractions have different denominators they're called unlike fractions.

To compare unlike fractions, we must first get a common denominator.

The common denominator of 8 and 16 will be the least common multiple of 8 and 16 or 16. To get a 16 in the denominator of 2/8, we multiply the numerator and the denominator by 2 which gives us 4/16.

Now notice that 4/16 is equal to 4/16 since we changed 2/8.

Since 4/8 equals 4/8, these fractions are the same

Answer:

V≈339.29cm³

Step-by-step explanation:

Answer:

The volume of the cylinder is approximately [tex]\( 339.292 \)[/tex] cubic centimeters.

Explanation:

To find the volume [tex]\(V\)[/tex] of a cylinder, you can use the formula:

[tex]\[ V = \pi r^2 h \][/tex]

Where:

- [tex]\( \pi \)[/tex] (pi) is a mathematical constant approximately equal to 3.14159

- [tex]\( r \)[/tex] is the radius of the base of the cylinder

- [tex]\( h \)[/tex] is the height of the cylinder

Given that the diameter of the base is 6 cm, the radius [tex](\( r \))[/tex] is half of that, so [tex]\( r = \frac{6}{2} = 3 \)[/tex]  cm.

The height [tex](\( h \))[/tex] of the cylinder is given as 12 cm.

Now, plug the values into the formula:

[tex]\[ V = \pi (3)^2 \times 12 \][/tex]

[tex]\[ V = 9\pi \times 12 \][/tex]

[tex]\[ V = 108\pi \][/tex]

Now, if you need a numerical approximation, you can multiply 108 by the value of [tex]\( \pi \)[/tex]:

[tex]\[ V \approx 108 \times 3.14159 \][/tex]

[tex]\[ V \approx 339.292 \][/tex]

Her average weekly income in August was $200.

Step-by-step explanation:

To find the income in july :

Given that,

Let,

'x' be the 100% of income she got in July.

Therefore, the income $207 in September is 115% of x.

⇒ 115% of x = 207

⇒ 1.15 × x = 207

⇒ x = 207 / 1.15

⇒ x = 180

∴ Her average weekly income in July was $180.

To find the income in August :

Given that,

Let,

'y' be the 100% of income she got in August.

Therefore, the income $180 in July is 90% of y.

⇒ 90% of y = 180

⇒ 0.9 × y = 180

⇒ y = 180/0.9

⇒ y = 200

∴ Her average weekly income in August was $200.

her average weekly income in August was $200 .

Step-by-step explanation:

Let in July income was x , So in September :

⇒ [tex]x+\frac{15x}{100}[/tex]

According to question , her average weekly income in September was $207 i.e.

⇒ [tex]x+\frac{15x}{100}=207[/tex]

⇒ [tex]\frac{115x}{100}=207[/tex]

⇒ [tex]x=207(\frac{100}{115})[/tex]

⇒ [tex]x=180[/tex]

Now , average weekly income in July was 10% less than it was in August , let income of august = y,  i.e.

Income in august = [tex]180+\frac{August(10)}{100}[/tex]

⇒ [tex]y=180 + \frac{y(10)}{100}[/tex]

⇒ [tex]\frac{9}{10}y=180[/tex]

⇒ [tex]y=\$200[/tex]

Therefore , her average weekly income in August was $200 .

Step-by-step explanation:

Solution:

Given that, A rectangle has:

[tex]height = 5y^3 \\\\width = 3y^3 - 8y^2 + 2y[/tex]

Express the area of the entire rectangle

[tex]\text{Area of rectangle } = 5y^3 \times (3y^3 - 8y^2 + 2y)[/tex]

[tex]Area = 5y^3\times \:3y^3+5y^3\left(-8y^2\right)+5y^3\times \:2y\\\\Area = 15y^6 -40y^5 + 10y^4 \\\\[/tex]

Standard form means that the terms are ordered from greatest exponent to lowest exponent

Thus area of entire rectangle in standard form is: [tex]15y^6 -40y^5 + 10y^4[/tex]

Answer:

In which step did Sierra make a mistake? Step 2.

What should she have done instead? add the x and the 5x

Step-by-step explanation:

she had the expression:

[tex]x + 8 + 5(x - 4)[/tex]

and then she multiplied the 5 by the parentheses (step 1):

[tex]x + 8 + 5x - 20[/tex]

no mistakes so far

then she has: [tex]5x + 8 - 20[/tex]  (step 2) Here is the mistake, she forgot about the 'x' that she has at the beginning of the expression.

What you should have done is add the x and the 5x, so she must a 6x in the following step (correcting the mistake):

[tex]6x+8-20[/tex]

which gives us:

[tex]6x-12[/tex]

Answer:

r = 24

Step-by-step explanation:

The formula for circumference is

C = 2*pi*r

48 pi = 2 * pi *r

Divide each side by  2pi

48 pi / 2pi = 2 * pi *r/ 2pi

24 = r

Answer:

4R+2S=24

Step-by-step explanation:

Let the raspberry be represented as R

Let the strawberry be represented as S

Since a carton of raspberry is$4=4R

Since a carton of strawberry is $2=2S

And the sum of the two is 24

4R+2S=24

Since a specific value is not given

So the final answer is

4R+2S=24

That would be [tex]\pi(32/2)^2\approx804.25\mathrm{ft^2}[/tex].

Answer:8

Step-by-step explanation:

Sandra wants to give a party for 60 people. Given that her punch recipe, which yields 2 gallons, serves 15 people, she can use a proportional relationship to determine she will need 8 gallons of punch.

This question can be solved by setting up a proportional relationship. In the given case, we know that the punch recipe produces 2 gallons of punch and serves 15 people. Hence, the ratio is 2 gallons per 15 people or 2/15.

Now, let's use this ratio to calculate how many gallons of punch she will need for 60 people. Form a proportion as follows:

2/15 = x/60

Where 'x' represents the number of gallons needed for 60 people. To find 'x', cross-multiply:

2 * 60 = 15 * x

120 = 15x

Then, divide both sides by 15 to solve for 'x':

x = 120/15

So, 'x' equals 8. That means Sandra needs to make 8 gallons of punch for her party.
