Answer:

Step-by-step explanation:

Every linear equation that is a conditional equation has one solution. However, not every linear equation in one variable has a single solution. There are two other cases: no solution and the solution set of all real numbers. resulting value on the right side will always be one greater than the value on the left side.

Answer:

x = 1.5

or

x = [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

First, move +7 to the other side of equation on the answer side and change it to it's absolute (in this case I mean negative) value:

3x + x = 13 - 7

Next, Simplify the equation:

4x = 6

Finally, Celebrate! You just (hopefully) learned how to solve this!

x = 1.5

or

x = [tex]\frac{1}{2}[/tex]

Answer:

  x = 4/5

Step-by-step explanation:

Subtract 3/x+4, then multiply by x/5:

  [tex]\dfrac{3}{x}+9=\dfrac{7}{x}+4\\\\5=\dfrac{4}{x}\\\\\boxed{x=\dfrac{4}{5}}[/tex]

_____

If you meant 3/(x+9) = 7/(x+4), you need to write it with parentheses around the denominator. (In that case, x=-12.75.)

Answer:

The answer would be y=-1/3x+1.

Step-by-step explanation:

To find the slope, you must use the formula y2-y1/x2-x1. That would make it 1-2/0-(-3) which the slope is -1/3. Now, using the formula y-y1=m(x-x1) which would be y-2=-1/3(x-(-3) if you plug it in. Solving the equation, you would get y=-1/3x+1.

Answer:

-2(x-8)=18-3(5x+6)

-2x+16=18-15x-18

-2x+15x=18-18+16

13x=16

X=16/13

Answer:

[tex]x=-\frac{16}{13}[/tex]

Step-by-step explanation:

[tex]-2(x-8)=18-3(5x+6)[/tex]

Start by distributing [tex]-2[/tex] into [tex](x-8)[/tex], and [tex]-3[/tex] into [tex](5x+6)[/tex]:

[tex]-2x+16=18-15x-18[/tex]

Combine like terms:

[tex]-2x+16=-15x[/tex]

Subtract [tex]16[/tex] from both sides of the equation:

[tex]-2x=-15x-16[/tex]

Add [tex]15x[/tex] to both sides of the equation:

[tex]-13x=16[/tex]

Divide both sides of the equation by the coefficient of [tex]x[/tex], which is [tex]-13[/tex]:

[tex]x=-\frac{16}{13}[/tex]

Answer:

Solve for  

x

by simplifying both sides of the inequality, then isolating the variable.

Does the name, Josh, Sound familiar? Maybe that'll ring a bell of why I'm saying this.

Answer:

Step-by-step explanation:

1. The graph looks like the vertex is at x = -1/2. So we can start with the equation y = (x +1/2)^2 +k. At x=0, this becomes 1 = 1/4 +k, or k = 3/4. The leading coefficient of 1 is consistent with the other points shown, so the equation is ...

  y = (x +1/2)^2 +3/4 . . . . vertex is (-1/2, 3/4)

  y = x^2 +x +1

__

2. The zeros appear to be at x=1 and x=4, so the factored form of the equation is ...

  y = a(x -1)(x -4)

At x = 0, this is ...

  12 = a(-1)(-4)

  3 = a

So, the equation is ...

  y = 3x^2 -15x +12

The values at the two points of interest are ...

  y = 3(-2-1)(-2-4) = 54 . . . . point (-2, 54)

  y = 3(5 -1)(5 -4) = 12 . . . . point (5, 12)

__

3. Using the vertex shown, the vertex form of the equation is ...

  y = a(x -2)^2 +7

Filling in the point (-2, -1), we can find the value of a:

  -1 = a(-2-2)^2 +7

  -8 = 16a

  a = -8/16 = -1/2

So, the equation is ...

  y = -1/2x^2 +2x +5

For x=0, the y-value is 5. The y-intercept is (0, 5).

Answer:

9514 1404 393

y = x^2 +x +1; (-1/2, 3/4)

y = 3x^2 -15x +12; (-2, 54), (5, 12)

y = -1/2x^2 +2x +5; (0, 5)  

1. The graph looks like the vertex is at x = -1/2. So we can start with the equation y = (x +1/2)^2 +k. At x=0, this becomes 1 = 1/4 +k, or k = 3/4. The leading coefficient of 1 is consistent with the other points shown, so the equation is ...

 y = (x +1/2)^2 +3/4 . . . . vertex is (-1/2, 3/4)

 y = x^2 +x +1

Answer:

1. Statistical Inference

2. Variability.

3. Outlier.

4. Population.

5. Sample.

Step-by-step explanation:

1. Statistical Inference: Reasoning from a sample to a population. For example, the average common entrance score of all examinees (population l) in New York city or a business that collects data from a random sample of 100 consumers and recorded whether they are male or female.

2. Variability: Successive observations of a system or phenomenon do not produce exactly the same result. For instance, the distribution having the same value of mean can have varying variability.

3. Outlier: An observation that differs considerably from the main body of the data. For example, in the following scores 1, 2, 3, 4, 50, 5, 60; both 50 & 60 is an outlier.

4. Population: The entire collection of objects or outcomes about which data are collected. For example, the number of new born babies in a hospital, the total number of football players in a soccer league.

5. Sample: A subset of the population containing the observed objects or outcomes and the resulting data from these objects or outcomes. For example, the average height of girls in a class having a population of 10 boys and 20 girls.

Answer:

The area of the shaded part is 100 [tex]cm^2[/tex]

Step-by-step explanation:

Subtracting Areas:

We can find the shaded area by adding or subtracting areas.

We'll use the latter method.

The total shape is a rectangle of side lengths 15 cm and 10 cm. Thus its area is:

[tex]A_t=15\ cm\cdot 10\ cm=150\ cm^2[/tex]

The area of each non-shaded square is:

[tex]A_s=(5\ cm)^2=25\ cm^2[/tex]

The total non-shaded area is

[tex]2*A_s=50\ cm^2[/tex]

Thus, the shaded area is:[tex]A_{shaded}=A_t-2*A_s=150 - 50 = 100[/tex]

The area of the shaded part is 100 [tex]cm^2[/tex]

Answer:

The ratio of the first term to the common difference is 1 : 2

Step-by-step explanation:

The rule of the sum of the AP is

[tex]S_{n}=\frac{n}{2}[2a+(n-1)d][/tex] , where

a is the first number

d is the common difference

n is the position of the number

∵ [tex]S_{10}[/tex] = 4 × [tex]S_{5}[/tex] ⇒ (1)

→ Find [tex]S_{10}[/tex]  and [tex]S_{5}[/tex]

∵ In [tex]S_{10}[/tex] n = 10

∴ [tex]S_{10}=\frac{10}{2}[2a+(10-1)d][/tex]

∴ [tex]S_{10}=5[2a+9d][/tex]

∴ [tex]S_{10}[/tex] = 10a + 45d ⇒ (2)

∵ In [tex]S_{5}[/tex] n = 5

∴ [tex]S_{5}=\frac{5}{2}[2a+(5-1)d][/tex]

∴ [tex]S_{5}=2.5[2a+4d][/tex]

∴ [tex]S_{5}[/tex] = 5a + 10d ⇒ (3)

→ Substitute (2) and (3) in (1)

∵ 10a + 45d = 4[5a + 10d]

∴ 10a +45d = 20a + 40d

→ Subtract 40d from both sides

∴ 10a + 45d - 40d = 20a + 40d - 40d

∴ 10a + 5d = 20a

→ Subtract 10a from both sides

∴ 10a - 10a + 5d = 20a - 10a

∴ 5d = 10a

→ Divide both sides by 5

∴ d = 2a

→ That means d is twice a or a is half d

∴ a : d = 1 : 2

The ratio of the first term to the common difference is 1 : 2

Answer:

28cm

Step-by-step explanation:

ive done this question before

Answer:

28 cm

Step-by-step explanation:

This is the answer because:

Perimeter = L + W + L + W

Area =  L x W

1) Since the shape is a square, there has to be two of the same factors that multiply.

_ x _ = 49

2) We know 7 x 7 = 49, therefore, w just have to add 7 + 7 + 7 + 7 which equals 28 cm

Therefore, the answer is 28 cm

Answer:

12%

Step-by-step explanation:

A percent is any fraction with 100 as a denominator. So [tex]\frac{12}{100}[/tex] is the same as 12% and 4 over 100 is the same as 4%

Here's an easy was to remember, there are 100 pennies to make a dollar that like per-CENT it's out of 100.

Hope that helps and have a great day!

Answer:

12%

Step-by-step explanation:

your question isn't giving me an option to answer but do 12 divided by 100 and you get a decimal, then multiply it by 100 which will give you the percentage. In this case is would be 12%

Answer:

$78.25

Step-by-step explanation:

Each adult = $11.50

Each child = $8.75

3 adults and 5 children

(11.50 x 3) + (8.75 x 5)

34.5 + 43.75 = $78.25

11.50 x 3 = 34.50

8.75 x 5 = 43.75

Given that,

A wave travels 1/3 mile in 1/20 hour.

How to calculate the distance in given time?

To calculate the value of distance at time is given as,

Distance = Speed X Time

To given condition wave travels 1/3 mile in 1/20 hour,

We calculate,

⇒ [tex]\frac{1}{3}[/tex] ÷ [tex]\frac{1}{20}[/tex]

Divide a fraction by multiplying its reciprocal,

Answer:

(3)(6)

Step-by-step explanation:

I did the quiz

George could have used the expression (0.30)(60) to determine 30% of 60.

George could have used the expression (0.10)(6)(0.10)(60) to determine 30% of 60.

(0.10) represents 10% or 0.10 as a decimal. Since 30% is three times 10%, George can use three instances of (0.10) to represent 30%.

(6) represents the value 6, which is the number being multiplied by the percentage.

(0.10)(60) represents 10% of 60, which is 6.

Multiplying (0.10)(6)(0.10)(60) gives us the result of 6, which is 30% of 60.

Therefore, George could have used the expression (0.10)(6)(0.10)(60) to calculate 30% of 60.
