4 The equation 5W + 3 = 4w + 9 is modeled below. w W 1 W W 1 1 W 1 1 W W 1 1 1 What value of w makes this equation true? Record your answer and fill in the bubbles on your answer document. Be sure to use the correct place value. MI - SI – PSA- S-
Answer:
w = 6.
Step-by-step explanation:
5w + 3 = 4w + 9
5w - 4w = 9 - 3
w = 6
Then, check your work!
5(6) + 3 = 4(6) + 9
30 + 3 = 24 + 9
33 = 33
So, w = 6 will be the correct answer.

Plz help answer this question
Answer:
Option I
Step-by-step explanation:
Let
[tex]f(x)=x^2+3x-28[/tex]
We know by subsitution,
[tex]f(-9)=(-9)^2+3(-9)-28=26>0[/tex]
[tex]f(0)=0^2+3(0)-28=-28<0[/tex]
[tex]f(5)=5^2+3(5)-28=12>0[/tex]
Since a quadratic equation only have 1 turning point, we know for some values a in (-9, 5) such that f(a)<0. And the option of the range of a must lie with in (-9, 5).
Therefore, only Option I is correct.

Find the length of "c" to the
nearest tenth using the
Pythagorean Theorem.
Enter
Answer:
10.6
Step-by-step explanation:
Pythagorean theorem: a² + b² = c²
Where a and b = the legs and c = hypotenuse
We are given two legs and need to find the hypotenuse
Given:
Short leg (a) = 7
Long leg (b) = 8
Hypotenuse = c
Now to find the value of c we simply plug in the values of the variables into the Pythagorean theorem and solve for c
Pythagorean theorem: a² + b² = c²
a = 7, b = 8, c = c
Plug in values
7² + 8² = c²
Now solve for c
Simplify exponents
49 + 64 = c²
Add
113 = c²
Taking the square root of both sides
c = 10.6 ( rounded to the nearest tenth )
Answer:
c = 10.6
Step-by-step explanation:
[tex]h {}^{2} = p {}^{2} + b {}^{2} \\ c {}^{2} = (8) {}^{2} + (7) {}^{2} \\ c = \sqrt{64 + 49} \\ c = \sqrt{113} \\c = 10.6[/tex]

what must be added to 2x^2 - 5x - 12 in order to get 7x^2 - x - 18
Answer:
5x^2 +4x -6
Step-by-step explanation:
that is the answer
yep
Answer:
5x² + 4x - 6
Step-by-step explanation:
Subtract 2x² - 5x - 12 from 7x² - x - 18 , that is the opposite operation, that is
7x² - x - 18 - (2x² - 5x - 12) ← distribute parenthesis by - 1
= 7x² - x - 18 - 2x² + 5x + 12 ← collect like terms
= 5x² + 4x - 6

Point B is on line segment AC. Given AB=4x-6, AC=2x+10, and BC=4, determine the numerical length of AC
Answer:
AC = 22
Step-by-step explanation:
AB + BC = AC , substitute values
4x - 6 + 4 = 2x + 10 , that is
4x - 2 = 2x + 10 ( subtract 2x from both sides )
2x - 2 = 10 ( add 2 to both sides )
2x = 12 ( divide both sides by 2 )
x = 6
Then
AC = 2x + 10 = 2(6) + 10 = 12 + 10 = 22
Jessica is selling books during the summer to earn money for college. She
earns a commission on each sale but has to pay for her own expenses.
After a month of driving from neighborhood to neighborhood and walking
door-to-door, she figures out that her weekly earnings are approximately a
linear function of the number of doors she knocks on.
She writes the equation of the function like this: E(x) = 10x - 30, where x is the
number of doors she knocks on during the week and E(x) is her earnings for
the week in dollars.
Which of the following are reasonable interpretations of the y-intercept of
Jessica's function?
Check all that apply:
A.) If she does not knock on any doors at all during the week, she will lose $30
B.) She can earn $10 per week even if she does not knock on any doors
C.) She will lose $10 per week if she does not knock on any doors
D.) Her expenses are $30 per week
Answer:
She can earn $10 per week even if she does not knock on any doors

In a school library, 40% of the books are in Nepali language, 40% of the remaining books are in English and the remaining books are in regional languages. If the number of books in English language is 4800, find the total number of books in the library,
Step-by-step explanation:
Solution,
Let the total number of books be x, then
Books in English language=4800
40% of x=4800
40/100×x=4800
40x/100=4800
40x=4800×100
40x=480000
x=480000/40
x=12000
So the total number of books in the library is 12000.

18(p+5) in a verbal expression
Answer:
Five greater than a number,the result is multiplied by 18
The verbal expression for 18(p + 5) is eighteen times the quantity obtained by adding five to a number p.
The verbal expression for the algebraic expression 18(p + 5) can be described as "Eighteen times the quantity obtained by adding five to a value represented by 'p'." This expression represents a mathematical operation where a given value 'p' is increased by five, and then the result is multiplied by eighteen. This type of expression is commonly encountered in various real-world situations where a value needs to be adjusted and then scaled up by a certain factor. In this case, the result reflects the outcome of multiplying the adjusted value by eighteen.

5. Use your answers to questions 3 and 4 to write an expression for how many times greater organism B's population is than organism A's population after 8 days. Simplify your expression, then write it as a number that is not in exponential form. Show your process. Write your answer in the space below. My answer
Population growth represents the rate at which the population changes
The expression for the number of times the population of B is greater than A is: [tex]2^6[/tex]The expression that is not in exponential form is: 64Given that:
[tex]r_1 = 2[/tex] ----- i.e. when the population doubles
[tex]r_2 = \frac{1}{2}[/tex] ----- i.e. when the population cut in halves
Population growth is represented as: [tex]A_n = ar^{n}[/tex]
Organism A
For the first 5 days (when it doubles) is:
[tex]A_5 = ar_1^{5[/tex]
Substitute [tex]r_1 = 2[/tex]
[tex]A_5 = a\times 2^{5[/tex]
For the next 3 days (when it cut in halves) is:
[tex]A = A_5 \times r_2^3[/tex]
Substitute [tex]A_5 = a\times 2^{5[/tex] and [tex]r_2 = \frac{1}{2}[/tex]
[tex]A= a \times 2^5 \times (\frac{1}{2})^3[/tex]
Apply law of indices
[tex]A = a \times 2^5 \times 2^{-3[/tex]
[tex]A = a \times 2^{5-3[/tex]
[tex]A = a \times 2^{2[/tex]
So, the growth factor of organism A is:
[tex]A = a \times 2^{2[/tex]
Organism B
For the 8 days, we have:
[tex]B=ar_1^8[/tex]
[tex]B=a\times 2^8[/tex]
The expression (n) for the number of times the population of B is greater than A is:
[tex]n = \frac BA[/tex]
This gives:
[tex]n = \frac{a \times 2^8}{a \times 2^2}[/tex]
[tex]n = \frac{2^8}{2^2}[/tex]
Apply law of indices
[tex]n = 2^{8-2}[/tex]
[tex]n = 2^{6}[/tex]
The expression that is not in exponential form is:
[tex]n = 2 \times 2\times 2\times 2 \times 2\times 2[/tex]
[tex]n = 64[/tex]
Hence:
The expression for the number of times the population of B is greater than A is: [tex]2^6[/tex]The expression that is not in exponential form is: 64Read more about population growth at:
