Write an equation of the line through the given point (-3, -6) with the given slope m = 3. Write the equation in slope-intercept
nlexa [21]
So we know that the slope intercept form is y=mx+b

so the formula is y=3*-3+-6

Can someone answer 15b
NISA [10]
A)

well, we know the elevator's rate is -20 f/s, ok, so every second, is dropping 20 feet, therefore, "y" is "distance from the ground floor", so when y = 0, meaning the distance to the ground floor is 0, so you ARE at the ground floor then.

and "x" is how many seconds you've been in the elevator.

now, she got in the elevator for 6 seconds, so, the elevator went down by 20 * 6, or 120 feet down, reason why the slope is negative, when she stopped, she was 350 feet away from the ground floor still though.

if the elevator went down 120 feet, and she's still 350 feet from the ground floor, that means  she boarded the elevator at 120 + 350 feet, or 470 feet.

b)

\bf \begin{array}{lcccllll}&#10;&\stackrel{\textit{elapsed seconds}}{x_1}&\stackrel{\textit{ft from ground-floor}}{y_1}\\&#10;%   (a,b)&#10;&({{ 6}}\quad ,&{{ 350}})&#10;\end{array}&#10;\\\\\\&#10;% slope  = m&#10;slope = {{ m}}= \cfrac{rise}{run} \implies -20&#10;\\\\\\&#10;% point-slope intercept&#10;\stackrel{\textit{point-slope form}}{y-{{ y_1}}={{ m}}(x-{{ x_1}})}\implies y-350=-20(x-6)&#10;\\\\\\&#10;y-350=-20x+120\implies  y=-20x+\stackrel{y-intercept}{470}

A sanitation company charges $4 per bag for garbage pickup plus a $10 weekly fee. A restaurant has 14 bags of g garbage. What wi
soldi70 [24.7K]

Answer:

<h2>$66</h2>

Step-by-step explanation:

Step one:

given data

charges

$4 per bag

$10 weekly fee

let the number of bag be x

and let the total charges be y

<em>the linear function for the total per week is</em>

<em>y=4x+10</em>

Step two:

the independent variable is the weekly fee of $10

for x=14

y=4(14)+10

y=56+10

y=$66

Answer:

The expressions for the payment made to Mary are,

(Monday) 90 = 15m + b

(Tuesday) 62 = 8m + b

where m and b are the fee per student and the base fee, respectively. Solving for m and b, the values are 4 and 30.

The equation that represents Mary's earning is

y = 4x + 30

For 20 students,

y = 4(20) + 30 = 110

For Lisa's earnings,

y = 8x + 15

Substituting 20,

y =8(20) + 15 = 175

Thus, Lisa would earn more than Mary by $65.

(Btw this is not my work, I got it from someone else on brainly and wanted to help lol)
