52+4y=12

We move all terms to the left:

52+4y-(12)=0

We add all the numbers together, and all the variables

4y+40=0

We move all terms containing y to the left, all other terms to the right

4y=-40

y=-40/4

y=-10

_______________________________________________________

3.1-3y=18

We move all terms to the left:

3.1-3y-(18)=0

We add all the numbers together, and all the variables

-3y-14.9=0

We move all terms containing y to the left, all other terms to the right

-3y=14.9

y=14.9/-3

y=-4+2.9/3

Answer:

$c=2d+5$

Step-by-step explanation:

Let

d ------> the number of days

c -----> the cost

we know that

The cost is equal to the number of days multiplied by $2 per day plus the initial fee of $5

The linear equation in slope-intercept form is

$c=md+b$

where

m is the slope

b is the c-intercept (value of c when the value of d is equal to zero)

in this problem we have

m=$2 per day

b=$5

substitute

$c=2d+5$

What is the sum of the series? Write in expanded form making sure to show all steps used to find the sum

pantera1 [17]

Answer:

-16

Step-by-step explanation:

k = 3

-2(3) + 5 = -1

k = 4

-2(4) + 5 = -3

k = 5

-2(5) + 5 = -5

k = 6

-2(6) + 5 = -7

(-1) + (-3) + (-5) + (-7)

= -16

The rate at which sand is poured into a bag is modeled by the function r given by r(t)=15t−2t2, where r(t) is measured in millil

balu736 [363]

Answer:

35 mililiters

Step-by-step explanation:

Given

$r(t) = 15t - 2t^2$

Required

Accumulated amount from t = 0 to 2

This implies that, we substitute the values of t from 0 to 2 in the function

$r(0) = 15*0 - 2*0^2= 0$

$r(1) = 15*1 - 2*1^2= 13$

$r(2) = 15*2 - 2*2^2= 22$

The accumulated sand (r) is:

$t = r(0) + r(1) + r(2)$

$r = 0 + 13 + 22$

$r = 35$
