Prove the polynomial identity. (2x−1)2+2(2x−1)=(2x+1)(2x−1) Drag and drop the expressions to correctly complete the proof of the polynomial identity. (2x−1)2+2(2x−1)=(2x+1)(2x−1) Response area+4x−2=(2x+1)(2x−1) Response area=(2x+1)(2x−1) Response area=(2x+1)(2x−1)
Answer:
Step-by-step explanation:
Given expression is,
(2x - 1)² + 2(2x - 1) = (2x - 1)(2x + 1)
To prove this identity we will take the left hand side of the equation and will prove equal to the right side.
(2x - 1)² + 2(2x - 1) = (2x - 1)(2x + 1)
4x² - 4x + 1 + 4x - 2 = (2x - 1)(2x + 1)
4x² - 1 = (2x - 1)(2x + 1)
(2x - 1)(2x + 1) = (2x - 1)(2x + 1) [Since a² - b² = (a - b)(a + b)]
Find values of a and b that make both equalities true: a/b = 2/5 and 22/a = 11/6 .
Answer:
a=32b=80Step-by-step explanation:
Find values of a and b that make both equalities true:
a/b = 2/5 and 22/a = 11/6 .
given that 22/a=11/16
cross multiply
11a=22x16
11a=352
a=352/11
a=32
put a=32 in a/b = 2/5 to find b we have
32/b=2/5
cross multiply we have
2b=32x5
2b=160
divide both sides by 2 we have
b=160/2
b=80
Answer:
Step-by-step explanation:
First, we will start by solving: 22/a = 11/6
Solving for a
We can first cross multiply and we get this: 22 x 6 = 11a, Simplified it would be 132 = 11a. Now we know that a = 12.
Solving for b
Now knowing a = 12 we can get this. 12/b = 2/5 same thing, cross multiply. That would be: 12 x 5 = b x 2, Simplified: 60 = 2b so b = 30

Netlfix charges $30 a month plus $5 per movie. Hulu charges $26 a month plus $7 per movie. How many movies will you need to watch for the Netflix membership to pay off and cost you less?
Answer:
3 movies
Step-by-step explanation:
From the information given, you can write an inequality that indicates that Netflix membership costs less than Hulu membership:
30+5x<26+7x
Now, you can solve for x:
30-26<7x-5x
4<2x
4/2<x

∠H = 3(20) - 2
∠H = 58
What is the value of the unknown in the equation 3m + 7 = - 23?
Answer:
Step-by-step explanation:
3m + 7 = - 23
we pass the -7 to the right with a positive sign
3m = -23 - 7
we perform the sum of negative numbers
3m = -30
we pass the -3 to the right to divide
m = -30/3
we perform the division
m = -10
Given the following functions: f(x) = x2 – 5 and g(x) = x - 3.
Find f(g(x))
Answer:
f(g)x))= x^2 -6x +4
Step-by-step explanation:
first, plug in g(x) into f(x): f(g)x)) =(x-3)^2 -5
then, you simplify the (x-3)^2 into (x-3)(x-3): f(g)x))= (x-3)(x-3) -5
when you distribute the two (x-3) you end up with: f(g)x))= x^2 -6x +9 -5
finally, you combine like terms and subtract 5 from 9 and your final answer is : f(g)x))= x^2 -6x +4
note: x^2 is x squared or exponent of 2
describe the translation from the red figure to the blue figure
Answer:
Step-by-step explanation:
From the figure attached,
Coordinates of point A → (2, 3)
Coordinates of point A' → (-3, 1)
Figure shows the translation of point A to point A'.
Relation → A(2, 3) → A'(-3, 1)
→ A'[(2 - 5), (3 - 2)]
Therefore, rule followed for the translation was,
(x, y) → [(x- 5), (y - 2)]

The age of earth’s crust is 5 · 10^9 years. Express this number as an integer.
Answer:
5,000,000,000 (see below)
Step-by-step explanation:
Integers are whole numbers and their opposites. That doesn't include fractions or decimals, even if they're negative. Being negative doesn't do anything, really.
For example, 5 and –5 are integers, but 5.1 or –5.3 are not integers. They're decimals, which means they're rational.
Integers also include 0.
Whole numbers do not include 0, so they're only 1, 2, 3, 4, 5, 6, 7, 8, 9 . . . and so on.
All whole numbers are integers.
So in order to find 5 × [tex]10^{9}[/tex] as an integer, you'll have to multiply the 5 and [tex]10^{9}[/tex] together.
[tex]10^{9}[/tex] is simply nine zeros, so it's: 1,000,000,000.
5 × 1,000,000,000 = 5,000,000,000
5,000,000,000 is not a decimal or fraction—and it also isn't negative. That means it's a whole number. Which qualifies it as an integer as well.

7. A fish tank hold 100 gallons of water and is losing water at a rate of 1 gallons per hour. A second fish tank
contains 40 gallons of water is having 2 gallons added per hour. After how many hours will the first tank
have less water than the second? Which inequality represents the situation?
a. 100+ h > 40 - 2h
c. 40-h > 100 + 5h
b. 100-h< 40 + 2h
d. 100-h > 40 + 2h

Question 8
My
Answer:
B
Step-by-step explanation:
the first fish tank has 100 gallons of water and 1 gallon is removed every hour which makes 100-h
the second tank has 40 gallons in it and 2 gallons are added every hour which makes 40+2h
after 20 hours the second tank will have more gallons than the first tank
this means that 40+2h would be greater than 100-h since it's also asking you "After how many hours will the first tank have less water than the second?"
There is no options to choose from and I need to find slope help due today
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
To find the slope we need two points.
A = ( -2 , 5 ) & B = ( 0 , 2 ) & C = ( 2 , -1 )
I choose A and B .
_________________________________
We have following equation to find the slope using two points.
[tex]slope= \frac{y(B) - y(A)}{x(B) - x(A)} \\ [/tex]
Now just need to put the coordinates in the above equation.
Let's do it...
[tex]slope = \frac{2 - 5}{0 - ( - 2)} \\ [/tex]
[tex]slope = \frac{ - 3}{2} \\ [/tex]
[tex]slope = - \frac{3}{2} \\ [/tex]

I suggest to find the slope using A , C
and B , C to can understand exactly what did I do buddy.

Write the equation of a line in point slope form that passes through (-1, 4), and is perpendicular to y = -4x +3
Answer:
y = 1/4x + 17/4
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
Perpendicular lines have the negative reciprocal slope.
m = 1/4
y = 1/4x + b
4 = 1/4(-1) + b
4 = -1/4 + b
17/4 = b
y = 1/4x + 17/4
