I am doing with Question Number 2

Let the two numbers be 'x' and 'y'.

According to the question, the product of two numbers is 14.

$x \times y=14$

So, xy=14 (Equation 1)

Now, one of the numbers is 3 ½ times the other.

So, $x = 3\frac{1}{2}\times y$

$x=\frac{7}{2}y$ (Equation 2)

Substituting the value of 'x' from equation 2 in equation 1, we get

$\frac{7}{2}y \times y = 14$

$\frac{7}{2}y^{2} = 14$

$y^{2} = 4$

So, y= 2 and -2

So, $x=\frac{14}{2}$ and $x=\frac{14}{-2}$

x=7 and -7

Numbers are 2,7 and -2,-7.

Sum of numbers 2 and 7 = 9

Sum of numbers -2 and -7 = -9.

there are seven people and Luisa's family they have four loaves of cinnamon bread to share equally Luisa wants to know how much

makvit [3.9K]

Answer:

$\frac{4}{7}$ of a loave of bread per person

Step-by-step explanation:

<u>Step 1: Convert words to expressions </u>

Seven people in Luisa's Family = <em>7 people </em>

Four loaves of cinnamon bread = <em>4 loaves </em>

<u>Step 2: Divide people from loaves </u>

4 loaves / 7 people <- This means they are splitting 4 loaves of bread between 7 people

$\frac{4}{7}$ of a loave of bread per person

Answer: $\frac{4}{7}$ of a loave of bread per person

I need some help with this one. Please give it a go! Thank you for your time!

Answer:

y = 4x - 3

Step-by-step explanation:

When we re-write the given equation into its slope-intercept form, it will like this:

y = (-1/4)x - 6

This line has a slope equal to -1/4 so the slope of the required line has a slope of +4 (perpendicular to the given line). Use this new slope and the given point P0(-1, -7) into this equation:

y - y0 = m(x - x0) ---> y + 7 = 4(x + 1)

Rearranging the terms into its slope-intercept form, we get

y = 4x - 3

Solve 8sin(pi/6 x) = 4 for the four smallest positive solutions

ryzh [129]

Simplify the given expression as shown below

$\begin{gathered} 8sin(\frac{\pi}{6}x)=4 \\ \Rightarrow sin(\frac{\pi}{6}x)=\frac{4}{8}=\frac{1}{2} \\ \Rightarrow sin(\frac{\pi}{6}x)=\frac{1}{2} \end{gathered}$

On the other hand,

$\begin{gathered} sin(y)=\frac{1}{2} \\ \end{gathered}$

Solving for y using the special triangle shown below

Thus,

$\begin{gathered} \Rightarrow y=30\degree\pm360\degree n=\frac{\pi}{6}\pm2\pi n \\ and \\ y=150\degree+360\degree n=\frac{5\pi}{6}+2\pi n \end{gathered}$

Then,

$\begin{gathered} \Rightarrow\frac{\pi}{6}x=y \\ \Rightarrow\frac{\pi}{6}x=\frac{\pi}{6}+2\pi n \\ \Rightarrow x=1+12n \\ and \\ \frac{\pi}{6}x=\frac{5\pi}{6}+2\pi n \\ \Rightarrow x=5+12n \end{gathered}$

The two sets of solutions are

$x=1+12n,5+12n$ <h2>Then, the four smallest positive solutions are</h2> $\Rightarrow x=1,5,13,17$ <h2>The answers are 1,5,13,17</h2>
