Well first you need to divide 4 by 12 which is 3. So 15/3=5 so she jarred in 5 days.
Answer:
{-3, 29, 21, 33}
Step-by-step explanation:
Substitute the x values (domain) to find y, do this for all x's-
f(x) = 6(-2) + 9 = -3
f(x) = 6(0) + 9 = 9
f(x) = 6(2) + 9 = 21
f(x) = 6(4) + 9 = 33
Range-
Take the y values and arrange it from least to greatest <em>(this matters and your teacher may most likely count it wrong if you do not put it in increasing order)</em>
{-3, 29, 21, 33}
X= # of residents
y= # of non residents
QUANITY EQUATION
x+y= 58
COST EQUATION
$13.00x + $17.50y= $925.00
SOLVE FOR 1 VARIABLE
x+y= 58
subtract y from both sides
x= 58-y
SUBSTITUTE IN 2nd EQUATION
$13.00x + $17.50= $925.00
13(58-y) + 17.50y= 925.00
multiply 13 by all in parentheses
(13*58)+(13*-y)+17.50y= 925.00
754-13y+17.50y= 925.00
combine like terms
754+4.50y= 925.00
subtract both sides by 754
4.50y= 171
divide both sides by 4.50
y= 38 number of non residents
SUBSTITUTE TO FIND X
x+y= 58
x+38= 58
x= 20 number of residents
ANSWER: 20 residents and 38 non residents attended.
CHECK:
$13.00(20) + $17.50(38)= $925.00
260 + 665= 925
925 = 925
Hope this helps! :)
