Answer:

Your answer is -4

Step-by-step explanation:

5 - (x - 2) { \\ }^{2}

where x = -1

Therefore, p(-1) = 5 - ( (-1) - 2 )²

= 5 - (-3)²

= 5 - 9

Ashley puts 45 stamps in an album. She puts the same number of stamps on each page,and 3 stamps on the last page. There are 2 mo
ludmilkaskok [199]
45 pages total
3 on last page
45-3=42
there are 42 on the rest of the pages
on each page, there are 2 more pages in album than then stamps on pages

amount of stamps on pages with equal number of stamps is
A=numberofpgest times number of stamps on pages
number of pages=p
number of stamps per papge=s
a=ps

2 more pages than stamps on pages
p=2+s
total number of stamps per page is s=(45-3)/(p-1)
(what I did is I first got rid of number of stamps on last page, then got rid of the last page)
P=2+s
s=(45-3)/(2+s-1)
s=42/(s+1)
times s+1 both sides
s^2+s=42
minus 42
s^2+s-42=0
factor
(s-6)(s+7)=0
set equal to zero
s-6=0
s=6

s+7=0
s=-7, false, no negative stamps


6 stamps per page

sub
p=2+s
p=2+6
p=8
8 pages

check
last page is 3 so 8-1=7 page left

7*6=42
3+42=45

correct


there are
8 pages in the album
6 stamps per page

Fill in the gaps in this sequence: -8, -19, -30, _ , _.<br> (Geometric and arithmetic sequences)
gavmur [86]

-8, -19, -30, -49 , -60

<u>Step-by-step explanation:</u>

Here we have the following sequence :

-8, -19, -30, _ , _

  • First term of sequence is -8 .
  • Second term of sequence is -19 : -8-11 = -19
  • Third term of sequence is -30 : -19-11 = -30
  • Fourth term of sequence is : -30-11 = -49
  • Fifth term of sequence is : -49-11 = -60  

Following sequence was an AP( Arithmetic Progression ) with first term as -8 i.e. a = -8 and common difference d = -11 having general equation as : -8 -11n .

What is the piecewise-defined function that expresses the cost of the order, C(x), in terms of the number of photos ordered, x?
Murljashka [212]

Answer:

See below

Step-by-step explanation:

The values in the table change by $3.80 from one line to the next. Since each change from line to line changes in number of photos by 20, the average cost per photo is $3.80/20 = $0.19. There is apparently a $5.80 -3.80 = $2.00 shipping charge for numbers of photos in the range shown in the table.

Thus, the piecewise function has 3 pieces:

for x < 100: $2.00 + 0.19x

for x < 200: $4.50 + 0.17x

for x ≥ 200: $0.15x

This could be written as ...

C(x)=\left\{\begin{array}{rcl}\$2.00+0.19x&\text{for}&0\le x

Will Mark Brainlest Help Please ,,,, ​
insens350 [35]

\\ \sf\longmapsto 2x+y=2

\\ \sf\longmapsto 2x=2-y

\\ \sf\longmapsto x=\dfrac{2-y}{2}\dots(1)

And

\\ \sf\longmapsto x+1=y+2

\\ \sf\longmapsto x=y+2-1

\\ \sf\longmapsto x=y+1

  • Put the value

\\ \sf\longmapsto \dfrac{2-y}{2}=y+1

\\ \sf\longmapsto 2-y=2(y+1)

\\ \sf\longmapsto 2-y=2y+2

\\ \sf\longmapsto 2-2=2y+y

\\ \sf\longmapsto 3y=0

\\ \sf\longmapsto y=\dfrac{0}{3}

\\ \sf\longmapsto y=\infty

  • Put in eq(1)

\\ \sf\longmapsto x=\dfrac{2-y}{2}

\\ \sf\longmapsto x=\dfrac{2-\infty}{2}

\\ \sf\longmapsto x=\dfrac{2}{2}

\\ \sf\longmapsto x=1
