Answer:

9 years old

Step-by-step explanation:

Let maggie's age be m,

and let maggie's brother's age be b

b = 2m - 5,

m + b = 22

Substitute "2m - 5" for b in the second equation (substitution)

m + (2m - 5) = 22 -> Remove parenthesis

m + 2m - 5 = 22 -> Combine like terms

3m = 22 + 5 = 27 -> Divide either side by 3

m = 27/3 = 9

Solution: Maggie is 9 years old

The potential roots of the function p(x) = x² - 9x² - 4x + 12 are x = 1, -1.5, and 12.

Degree of a polynomial is the highest power of the variable in that polynomial. For example, in a cubic polynomial, the variable [\(\bold{x}\)] has the highest power of 3.

Given is the following function with degree of 2 as -

We will plot the graph and find the roots of this function. The number of x - intercepts [coordinates where the graph cuts the x axis] will give us the roots or zeroes of the polynomials. Refer to the graph attached, it shows that the graph intercepts the x - axis at three different coordinates which are → x = 1, x = -1.5, and x = 12. Hence, these three values of [x] are the potential roots of the function p(x) = x² - 9x² - 4x + 12.

Therefore, the potential roots of the function p(x) = x² - 9x² - 4x + 12 are x = 1, -1.5, and 12.

The potential roots of the given polynomial equation are +4 and -3. These roots are found by factoring the equation, setting each factor equal to zero and solving for x.

To find the potential roots of the polynomial equation p(x) = x² - 9x - 12, we can set the equation to zero and solve for x: 0 = x² - 9x - 12.

Next, we look for the factors of 12 which when multiplied would give you -12 and when subtracted would give you 9. There we have -4 and +3. Therefore the factors of the equation are (x - 4)(x + 3) = 0.

So, Final answer:

The potential roots of the given polynomial equation are +4 and -3. These roots are found by factoring the equation, setting each factor equal to zero and solving for x.

To find the potential roots of the polynomial equation p(x) = x² - 9x - 12, we can set the equation to zero and solve for x:

0 = x² - 9x - 12.

Next, we look for the factors of 12 which when multiplied would give you -12 and when subtracted would give you 9. There we have -4 and +3. Therefore the factors of the equation are (x - 4)(x + 3) = 0.

So, potential roots of the equation are x = 4 and x = -3 if we set each factor equal to zero and solve for x. This means that from the given options, the potential roots to the equation would be +4 and -3 (though -3 is not mentioned). of the equation are x = 4 and x = -3 if we set each factor equal to zero and solve for x. This means that from the given options, the potential roots to the equation would be +4 and -3 (though -3 is not mentioned).

Answer:

y=-5x+5

Step-by-step explanation:

The best description for the roots is double root. Option A

We know that the discriminant is the value that can be able to tell us the nature of the roots that we have in the equation. The roots of the equation would tell us more about how the equation can be approached.

Now we have the equation; 2x^2 + 7x + 6 = 0

a = 2, b = 7, c = 6

Using the formula;

√b^2 - 4ac

√(7)^2 - (4 * 2 * 6)

√49 - 48

Answer:

B. x = 0

Step-by-step explanation:

we notice that a point and it’s image have the same y-coordinate and opposite x-coordinates

Example :

A(-2 , 2) is a point and A(2 , 2) it’s image by the reflection

\(y_{A}=2=y_{A^{\prime }}\)

\(x_{A}=-2=-x_{A^{\prime }}\)

Then the reflection is across the y-axis

The simplified exponential expression for this problem is given as follows:

D. 1/49.

The exponential expression for this problem is defined as follows:

\(7^{-\frac{5}{6}} \times 7^{-\frac{7}{6}}\)

When two terms with the same base and different exponents are multiplied, we keep the base and add the exponents.

Hence the exponent is given as follows:

-5/6 - 7/6 = -12/6 = -2.

The negative exponent is moved to the denominator, hence:

1/7² = 1/49.

Answer:

S = 2π(3^2) + 2π(3)(8.2) = 67.2π = 211 cm^3

Step-by-step explanation:

P(A) = 0.47

P(B) = 0.53

P(A|B) = 0.57

a. Probability that at least one stock will rise is equal to P(A u B)

= P(A) + p(B) - P(A n B)

= (O.47+0.53)-(0.53*0.57)

= 1-0.3021

= 0.6979

b. Events A and B are not mutually exclusive. This is because P(AnB)≠0

P(AnB) = p(B).P(A|B)

= 0.53x0.57

= 0.3021 and this value is not equal to 0

c. No, events A and B are not independent. This is because P(A|B) ≠ P(A)

Since we have

p(A) as 0.47

P(A|B) as 0.53

Tom earns $100 in 5 days if he makes $5622 in 281.10 day, in the given arithmetic problem.

A branch of mathematics that deals with the properties of numbers is known as arithmetic, which uses the four operations. A branch of mathematics that deals with the properties of numbers is known as arithmetic, which uses the four operations.

The four operations are addition, subtraction, multiplication, and division. The guidelines for each procedure are very specific.

One of the fundamental principles of addition and subtraction is that while addition increases a number's overall value, subtraction decreases it.

Given that he earn $5622 in 281.10 day

In 1 day he earns = 5622/281.10

                             = $20

So in 5 days he earns = 5 × $20

                                     = $100

The length AC in the kite is 8.7 cm.

A kite is a quadrilateral that has two pairs of consecutive equal sides and

perpendicular diagonals. Therefore, let's find the length AC in the kite.

Hence, using Pythagoras's theorem, let's find CE.

Therefore,

7² - 4² = CE²

CE = √49 - 16

CE = √33

CE = √33

Let's find AE as follows:

5²- 4² = AE²

AE = √25 - 16

AE = √9

AE = 3 units

Therefore,

AC = √33 + 3

AC = 5.74456264654 + 3

AC = 8.74456264654

AC = 8.7 units

Answer:

20.2 %

Step-by-step explanation:

A typical high-income household in 1980 earned $140,397.

A similar household in 2009  earned $168,727.

We need to find the relative increase in income for these households from  1980 to 2009.

It can be calculated as follows :

\(\%=\dfrac{168727-140397}{140397}\times 100\\\\=20.17\%\\\\=20.2\%\)

So, the required percent is 20.2%.

Subtract 25 from both sides;

13x < -26

Divide both sides by 13;

x < -2

-9x + 5 < 17

Subtract 5 from both sides;

-9x < 12

Divide both sides by -9

The median is the middle number in the data set when the data set is written from least to greatest.

The median is the number in the middle when arranged in an ascending order. The numbers will be:

0, 3, 4, 6, 6, 7, 7, 7, 9.

The median is 6.

The range is the difference between the highest and lowest number which is: = 9 - 0 = 9

The mode is the number that appears most which is 7.

The mean will be the average which will be:

= (0 + 3 + 4 + 6 + 6 + 7 + 7 + 7 + 9) / 9.
