Answer:
[tex](2x + 1)^{2} - 4x(x - 1) = 7 \\ (2x + 1)(2x + 1) - 4 {x}^{2} + 4x = 7 \\ 4 {x}^{2} + 4x + 1 - 4 {x}^{2} + 4x = 7 \\ 8x + 1 = 7 \\ 8x = 7 - 1 \\ 8x = 6 \\ \\ x = \frac{6}{8} \\ \\ x = \frac{3}{4} \\ \\ x = 0.75[/tex]

What do you add to
2 1/5 to make 5
Answer:
Another 2 1/5
Step-by-step explanation:
2.5 + 2.5 = 5.0 (You don't have to put the .0)
Another example would be:
5.5 + 5.5 = 11.0 (Again, you do not have to put the .0)

Which is the equation of the function?
Step-by-step explanation:
A function is an equation that has only one answer for y for every x. A function assigns exactly one output to each input of a specified type. It is common to name a function either f(x) or g(x) instead of y. f(2) means that we should find the value of our function when x equals 2.

Special angle pairs?
Answer:
x = 113, y = 67
Step-by-step explanation:
y and 67 are vertically opposite angles.
Vertically opposite angles are equal.
y = 67
x and 67 are linear pair angles.
Sum of linear pair angles is 180,
x + 67 = 180
x = 180 - 67
x = 113
What is (a^6)^3 divided by (a^5)^2? (Please explain using steps.)
Answer:
(a^6)^3 / (a^5)^2 = a^8
Step-by-step explanation:
step 1: multiply the exponents that are on the outside of the parenthesis to the exponent inside the parenthesis
ex: a^6 * ^3 / a^5 * ^2 = a^18 / a^10
step 2: subtract the exponents
ex: a^18 - ^10 = a^8

What is 11 1/20 as a decimal?
11,05
Step-by-step explanation:
11 1/20
= (11 × 20 + 1)/20
= (220 + 1)/20
= 221/20 → times 5
= 1105/100
= 11,05
Answer:
11.05
Step-by-step explanation:
To convert a fraction to a decimal, multiply the fraction by [tex]\frac{x}{x}[/tex], x being the number that will multiply with the denominator to equal 100.
In this case, the value of x would be 5 because 20 × 5 = 100.
Now, multiply [tex]\frac{1}{20}[/tex] × [tex]\frac{5}{5}[/tex]:
[tex]\frac{1}{20}[/tex] × [tex]\frac{5}{5}[/tex] = [tex]\frac{5}{100}[/tex]
5 hundredths is equal to 0.05, so 11[tex]\frac{1}{20}[/tex] = 11.05.
A large koi pond is filled from a garden hose at the rate of 12 gal/min. Initially, the pond contains 200 gal of water.
(a) Find a linear function V that models the volume of water in the pond at any time t.
(b) If the pond has a capacity of 1304 gal, how long does it take to completely fill the pond?
a) The linear function that models the amount of water after t minutes is given by:
[tex]V(t) = 200 + 12t[/tex]
b) It takes 92 minutes to completely fill the pond.
Item a:
Initially, the pond contains 200 gal of water, that is, the linear function has a y-intercept of 200.Filled at a rate of 12 gallons per minute, thus the linear function has a slope of 12.Then, the function is:
[tex]V(t) = 200 + 12t[/tex]
Item b:
It takes t minutes to fill the pond, t is found for which:
[tex]V(t) = 1304[/tex]
Then
[tex]200 + 12t = 1304[/tex]
[tex]12t = 1104[/tex]
[tex]t = \frac{1104}{12}[/tex]
[tex]t = 92[/tex]
It takes 92 minutes to completely fill the pond.

Question is in the pic :)
Answer:
Since +P looks to be 7, -P would be -7
Hope this helps :)
Answer:
-7
Step-by-step explanation:
P is a variable, and P can only have 1 value. Thanks to the number line, we know what this value is. P is positive 7. If we know that the set value of P is positive 7, then we can just treat it like it is positive 7.
P - 5 = 2
P + 3 = 10
So putting a negative sign in front of P will mean it will be

Given the explicit rule, F(n) = 250 + 130(n-1), what is the 12th term?
Of(12)=-$1180
Of(12)= $1810
O f(12)= $1680
Of(12)=-$1050
Answer:
f(12) = 1680
Step-by-step explanation:
Substitute n = 12 into f(n) , that is
f(12) = 250 + 130(12 - 1) = 250 + 130(11) = 250 + 1430 = 1680

what is the slope of all lines parallel to the line 4x-5y+-1?
a -5/4
b 5/4
c-1/5
d4/5
Given equation of the line ,
[tex]\implies 4x - 5y +(-1) = 0 [/tex]
Simplify ,
[tex]\implies 4x - 5y - 1 = 0 [/tex]
Transpose terms to RHS ,
[tex]\implies 5y = 4x - 1 [/tex]
Divide both sides by 5 ,
[tex]\implies \boxed{ y =\dfrac{4}{5}x -\dfrac{1}{5}}[/tex]
Now we know the slope intercept form of the line as [tex] y = mx + c [/tex] we have ,
