Answer:
x = 3
Explanation:
⇒ 4 - 7(x) = 1 - 6(x)
⇒ -7(x) + 6(x) = 1 - 4
⇒ -(x) = -3
⇒ x = 3
Check:
4 -7(3) = 1-6(3)4 - 21 = 1 - 18-17 = -17Hence, x = 3 confirmed as L.H.S = R.H.S

The molar mass of AlCl3 is 133.34 g/mol. How many molecules of AlCl3 are there in 2 g?
To solve this problem, we have to apply mole-concept to this and we would need the molar mass of AlCl3. 2g of AlCl3 contains 9.034*10^21 molecules.
Number of Molecules in 2g of AlCl3The molar mass of AlCl3 is given as 133.34g/mol
Data;
mass = 2gmolar mass = 133.34g/molUsing the mole concept, we can equate the molar mass to the number of molecules present in the entity.
[tex]133.34g = 6.023*10^2^3[/tex]
If we equate this
[tex]133.34g = 6.023*10^2^3\\2g = x molecules\\x = \frac{2*6.023*10^2^3}{133.34} \\x = 9.034*10^2^1 molecules[/tex]
From the calculations above, 2g of AlCl3 contains 9.034*10^21 molecules.

Answer:
B) d=4t
Step-by-step explanation:
let's look at two points
1. t=0, d = 0
2. t = 1, d = 4
slope = change in vertical axis (d)/ change in horizontal axis (t)
change in d = 4 = d₂-d₁
change in t = 1 = t₂-t₁
slope = 4/1 = 4
vertical variable = slope * horizontal variable + horizontal axis intercept
d = 4 * t + horizontal axis intercept
horizontal axis intercept is the vertical axis variable (d) when the horizontal axis variable (t) is at 0. at t=0, d=0
thus, d = 4 * t + 0
d = 4t (B)

Vertex form of a functionThis are used to determine the maximum or minimum of a function. Give the quadratic equation expressed as:
y = 3x² + 12x + 7
The vertex form of the function will be in the form y = a(x-h)² + k
Complete the square
y = 3(x² + 4x) + 7
y = 3(x² + 4x + 2² - 2²) + 7
y = 3(x+2)² - 3(4) + 7

Students at Green High School and students at Belle High School planned separate field trips to Washington, D.C. Green High School filled three buses (x) and one van (y) with 118 students. Belle High School filled four buses and two vans with 164 students.
The situation above is represented by the following system of equations:
3x + y = 118
4x + 2y = 164
The solution is (36,10)
Explain what the system of equations and the solution both represent.
Step-by-step explanation:
The system of equations for eq 1 which is 3x + y = 118 represents the Green High School which filled three buses(with a specific number of students identified as x) and a van(with a specific number of students identified as y) with a total of 118 students.
for eq 2; 4x + 2y = 164; represents Belle High School which filled four buses(with a specific number of students identified as x) and two vans(with a specific number of students identified as y) with a total of 164 students.
The solution represents the specific number of students in the buses and vans in eq1 and eq 2 with x being 36 students and y being 10 students.
substituting 36 for x and 10 for y in eq 1;
3(36) + 10 = 108 + 10 = 118 total students for Green High School
substituting 36 for x and 10 for y in eq2;
4(36) + 2(10) = 144 + 20 = 164 total students for Belle High school

Glen Davis is shooting free throws. Making or missing free throws doesn't change the probability that he will make his next one, and he makes his free throws 74\%74%74, percent of the time.
Answer: Choice D [tex](1-0.74)^4[/tex]
Reason:
74% = 0.74 represents the probability of him making any given free throw.
This means 1 - 0.74 is the probability of him missing.
Getting four misses in a row has a probability of (1-0.74)^4 which is the same as writing [tex](1-0.74)^4[/tex]
In other words, we multiply exactly four copies of (1-0.74) to get our answer.
