Answer:

Torrance spends 16$ on his brother

Step-by-step explanation:

You have 100$

So, we have

x (brother) + x (sister) + x (mother) = 100

But, since 10$ less will be spent on the sister than the brother, it becomes (x - 10) and twice + 6$ is spent on the mom, it also becomes (2x + 6)

Our equation then becomes

(x - 10) + x + (2x + 6) = 100

X will end up equaling 26. This is how much is spent on the sister.

(x - 10) will be substituted for (26 - 10), which equals 16.

I'm not sure if this is right so you might want to check with somebody (since I may be wrong) I hope this helps you understand how to basically do it though. <3

Answer:

-12y+24

Step-by-step explanation:

I used math---------way , so it is correct. brainliest please!

Answer:

Step-by-step explanation:

6 (-2y+4)

First, we use the distributive property to substitute the terms.

(-12y + 24)

Then we divide 24 by -12 to get -2.

24/-12 = -2.

y = -2

In a data set, the number of items that are in a particular category is called the frequency

Frequency can be defined as the number of items that are in a particular category in a data set.

It is also described as the number of times the value \appears in the data set.

The distribution of a variable is defined by the pattern of frequencies, this means that, the set of all possible values and the frequencies associated with these values

Frequency distributions are also portrayed as frequency in tables or charts,

It is also important to note that relative frequency is the proportion of items  in a particular category in a data set.

Hence, it is the frequency

Answer:

see explanation

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k ) are the coordinates of the centre and r is the radius

Given

x² + y² + 10x - 6y + 14 = 0 ( collect the x/ y terms together and subtract 14 from both sides )

x² + 10x + y² - 6y = - 14

Using the method of completing the square

add ( half the coefficient of the x/ y terms )² to both sides

x² + 2(5)x + 25 + y² + 2(- 3)y + 9 = - 14 + 25 + 9

(x + 5)² + (y - 3)² = 20 ← in standard form

with centre = (- 5, 3 ) and r = [tex]\sqrt{20}[/tex] = 2[tex]\sqrt{5}[/tex]

Answer:

3rd option

Step-by-step explanation:

(f • g)(x)

= f(x) × g(x)

= (3x + 1)(2x + 7)

Each term in the second factor is multiplied by each term in the first factor, that is

3x(2x + 7) + 1(2x + 7) ← distribute parenthesis

= 6x² + 21x + 2x + 7 ← collect like terms

The sample size that's given is 62 and the probability of success will be 0.68.

From the complete question, it can be noted that the sample size that's given is 62 while the number of samples is 42.

In this case, the probability of success will be:

= Number of samples / Sample size

= 42/62 = 0.68

To solve the equation [tex]2^{x-1} - 7 = 9[/tex], we add 7 to both sides make the bases the same, and equate the exponents.

Some common rules of exponents are

xᵃ×xᵇ = xᵃ⁺ᵇ.

xᵃ/xᵇ = xᵃ⁻ᵇ.

Addition and subtraction of exponents are only possible for the same base value and when the base is different and both have the same exponent we just multiply the bases and write the exponent.

Given, An exponential expression

[tex]2^{x-1} - 7 = 9[/tex].

[tex]2^{x -1} = 9 + 7.[/tex]

[tex]2^{x-1} = 16.[/tex]

keeping in mind that perpendicular lines have negative reciprocal slopes, let's check for the slope of the equation above

[tex]y=\stackrel{\stackrel{m}{\downarrow }}{-\cfrac{2}{3}} x+6\qquad \impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}[/tex]

well, we know that "m"  is perpendicular to the line above, so that means that line "m" has a slope of

[tex]\stackrel{~\hspace{5em}\textit{perpendicular lines have \underline{negative reciprocal} slopes}~\hspace{5em}} {\stackrel{slope}{-\cfrac{2}{3}} ~\hfill \stackrel{reciprocal}{-\cfrac{3}{2}} ~\hfill \stackrel{negative~reciprocal}{-\cfrac{3}{-2}\implies \cfrac{3}{2}}}[/tex]

keeping in mind that parallel lines have exactly the same slope, and since we know that "n" is parallel with "m", that means that if "m" has a slope of 3/2 than "n" must have the same slope.

so we're really looking for the equation of a line whose slope is 3/2 and passes through (4 , -3)
