It says less than so you want to subtract.
an number with be represented by the variable n:
n-9
it isn't 9 minus n because that would be nine less a number(9-n)
so your answer is:
n-9

Write an equation for a line perpendicular to y=3x+1 and passing through the point (6,2)

Ymorist [56]

Answer:

$y = -\frac{1}{3}x + 4$

Step-by-step explanation:

Required

Equation of line

passes through $(6,2)$

In an equation of the form $y =mx + b$ ; the slope is $m$

So, by comparison;

The slope of $y = 3x + 1$ is: $m =3$

From the question, we understand that the required equation is perpendicular to $y = 3x + 1$

This means that its slope is:

$m_2 =-\frac{1}{m}$

So, we have:

$m_2 =-\frac{1}{3}$

The line equation is:

$y = m_2(x - x_1) + y_1$

Where:

$(x_1,y_1) = (6,2)$

So, we have:

$y = -\frac{1}{3}(x - 6) + 2$

$y = -\frac{1}{3}x + 2 + 2$

$y = -\frac{1}{3}x + 4$

Mila is working two summer jobs, making $9 per hour babysitting and $17 per hour lifeguarding. Last week Mila earned a total of

aksik [14]

Mila spent 4 hours at baby sitting and 6 hours at life guarding

Solution:

Given that, Mila is working two summer jobs, making $9 per hour babysitting and $17 per hour life guarding

Amount earned from babysitting = $ 9 per hour

Amount earned from life guarding = $ 17 per hour

Last week Mila earned a total of $138 and worked 2 more hours life guarding than hours babysitting

Let "b" represent the number of hours spent babysitting

Then, the number of hours spend at life guarding is b + 2

Also, total amount earned last week = $ 138

Then, we can frame a equation as:

Amount earned from babysitting x number of hours spent babysitting + Amount earned from life guarding x number of hours spend at life guarding = 138

$9 \times b + 17 \times (b+2) = 138\\\\9b + 17b + 34 = 138\\\\26b = 138 - 34\\\\26b = 104\\\\b = 4$

Then, number of hours spent at life guarding:

b + 2 - 4 + 2 = 6 hours

Thus she spent 4 hours at baby sitting and 6 hours at life guarding

Anna's salary is four times Emily's salary. They decide to share the cost of a $120 gift card. Anna will contribute four times a

Kruka [31]

Answer:

Emily will contribute $24 and Anna will contribute $96

Step-by-step explanation:

From the given information:

Let Emily's salary be x

and let Anna's salary be 4x since Anna's salary is four times Emily's salary.

They were to share the cost of a $120 gift card.

SO, x+4x = 120

5x = 120

x = 120/5

x = 24

Therefore, Emily will contribute x = $24

and Anna will contribute 4x = 4 × $24 = $96
