Answer:

if y = 5 than 2x - 5 = 5 we can simplify this too 2x = 10 ( by adding the 5 to both sides ) now we can simplify and get x = 5 ( by dividing by 2 ) so we get (5,5) as our first point. well since its in slope intercept form ( y = mx + b ) we can graph it.

Find the second term of the arithmetic series described by a1=0.25, an=4, and sn=8.5 answer: a2=

Elis [28]

Answer:

Step-by-step explanation:

an=4=a1+(n-1)*d=0.25+(n-1)*d

so (n-1)*d=4-0.25=3.75

Sn=a1*n+(n-1)*d

a1*n+3.75=8.5

0.25*n+3.75=8.5

-3.75 -3.75

0.25*n=8.5-3.75=4.75

n=4.75:0.25

n=19

so a19=a1+(19-1)*d=4

0.25+18*d=4

-0.25 -0.25

18*d=3.75

d=3.75/18

d=0.208

so a2=a1+0.208=0.25+0.208=0.458

a2=0.458

Answer:

D. 144

Step-by-step explanation:

find the volume of the shipping container and divide it by the volume of a box.

$2\frac{2}{3}$ × $1$ × $2$ = $\frac{16}{3}$

$\frac{1}{3}$ × $\frac{1}{3}$ × $\frac{1}{3}$ = $\frac{1}{27}$

$\frac{16}{3}$ divided by $\frac{1}{27}$ is 144.

PART A: health inspector: 7,14,21,28,35,42,49,56,63,70,77,84..........

PART A:same thing for the fire inspector, except this time your adding 12+12+12, and so on:

PART A: fire inspector: 12,24,36,48,60,72,84,96.......

PART B: and to figure out what day they will both come is you have to find the LCM (least common multiple)

PART B: which in this case is Day 84
