Answer:

[tex]\frac{4a-2}{2a+1}[/tex]

Step-by-step explanation:

Factorise the numerator and denominator

8a² - 2 ← factor out 2 from each term

= 2(4a² - 1) ← 4a² - 1 is a difference of squares

= 2(2a - 1)(2a + 1)

4a² + 4a + 1 ← is a perfect square

= (2a + 1)²

Thus

[tex]\frac{8a^2-2}{4a^2+4a+1}[/tex]

= [tex]\frac{2(2a-1)(2a+1)}{(2a+1)(2a+1)}[/tex] ← cancel (2a + 1) on numerator/ denominator

= [tex]\frac{2(2a-1)}{2a+1}[/tex]

= [tex]\frac{4a-2}{2a+1}[/tex]

Answer:

Step-by-step explanation:

In this problem, we want to write a model/equation that will represent the cost of producing a phone

Given, labor and materials cost per phone is $100

the cost of producing 8 phones a day is $1300

let us find the cost of producing one phone a day

8 phone is produced for $1300

1 phone will be for x

x= 1300/8

x=$162.5

The cost of producing a phone in a  day is $162.5

therefore the of producing p phone in a day is 162.5p

if C represents the total cost of producing a phone

then total cost, in dollars, of producing p phones in a given day.

C=100+162.5p

Answer: C = 100p + 500

This is the correct awnser

Answer:

No because by definition, theres is no exact 90 degree angle to form a Right angle triangle

Answer:

No this triangle is not a right angle because right angle have exactly 90° value, corresponding to quarter turn.

Answer:

-7/3 & 5/2

Step-by-step explanation:

3x +7 = 0

3x = -7

x = -7/3

2x-5=0

2x = 5

X = 5/2

Answer:

y = 3x + 1

Step-by-step explanation:

y = mx + b

The slope, or m, is 3.

The y-intercept, or y, is 1.

Plug them into the equation.

y = mx + b

y = 3x + 1

Answer:

$216

Step by step

Explanation:

First we subtract  $ 20 from  $ 84  giving us a total of  $ 64 and when we add that to  $ 152  we get  $ 216

.

Answer:

-60

Step-by-step explanation:

C. 7/2x -2.

Because slope is positive, y intercept is -2.

7/2 because if rise over run

Answer:

They want you to have a good "grasp" of algebra... since you're asking about this I'm going to guess you don't feel that comfortable with it ... so I'll go in detail below. Even thought this is exactly what your math teacher is supposed to be teaching you.. ask your math teacher if I can have part of their salary :) $$

Step-by-step explanation:

in Question 18 , they are asking to solve for y  .  what that means is they want an equation that looks like  y= (some stuff)  In math terms they are asking you to isolate the y ...  which is the part your math teacher should have told you.. were you just not listening? :P Anyway,  soooo to solve for y we want to get y by it self.. on one side of the = sign and everything else on the other.. to do this use the order of operations ... but.. for doing algebra it has to be done in reverse order :0.... which i'm sure your math teacher hasn't mentioned and partly why algebra is so difficult.  

soooo  solve for 'y' ( isolate y )

12x-4y=20

-4y=20-12x

y=(20-12x)/-4

Yes, I know.. that answer is not very "satisfying"  but. that is solved for "y"

for Question 20 it's just straight algebra, no numbers.. it's more abstract...and solve for R ( isolate 'R')   to get  R by itself

P=(R-C) / N

I'm multiplying by N first b/c the next thing in those parenthesis and when you do the order of operations you'd usually to that first but remember we are going back wards in operations.. sooo  multiply both sides by N

P*N=R-C  ..  

now that R-C is no longer in parenthesis we can do that addition of C to both sides..  this is kinda tricky b/c of how the R-C were both over the N  anyway...

P*N +C=R

another way to think of this one.... maybe you don't want to and you can just skip this part if you want to be done...

P=(R-C)/N

P=R/N - C/N  now we can do addition first .. like I was mentioning above

P+C/N = R/N   multiply both sides by N

N(P+C/N)=R   b/c N/N =1 just drop it from the R'

P*N +C =R   we end up at the same place but my a different route.

Answer:

A ) $1.75 x  ≤ $25

Step-by-step explanation:

the cost of x boxes of crayons = 1.75x dollars

If there is a budget of only $ 25,

So, the cost of x boxes of crayons ≤ $25

Answer:

Since his budget is 25, it's less than or equal to ( ≤ 25). That means your answer would be A  $1.75x ≤ $25 because 1.75 times the amount of crayons can't go over the $25 budget.
