Which equation will create a system of equations with infinitely many solutions?
A) 3x - y=5
B) -3x +y=5
C) 12x + 4y = 20
D) 12x - 4y= 20
Answer:

Step-by-step explanation:
for infinitely many solutions, ratio of coefficients should be equal.
since ratio = 1/4 so they will have infinitely many solutions.

There's no specific formula to find the square root of a number, however we can find the square root of a number by the following methods:
i) By Prime Factorisation
ii) By Long Division
iii) By Repeated subtraction method
✏ By Prime Factorisation:Step I: Obtain the given number.
Step II: Reduce the given number into prime factors by successive division.
Step III: Now make pairs of prime factors in such a way that both the factors in each pair are equal.
Step IV: Take one factor from each pair and find the product of these factors.
Step V: The product obtained by multiplying the factors is the required square root.
✏ Long Division:Step 1: Firstly, we place a bar on every pair of digits starting from the unit digit. If the number of digits in it is odd, we put a bar on the single-digit too.
Step 2: Now we find the largest number whose square is less than or equal to the 1st number.
Step 3: Now we bring down the next bar number.
Step 4: For new divisor, we add the divisor & quotient.
Step 5: Number taken is the product of a new divisor and this digit is equal to or less than the new dividend.
✏ Repeated subtraction method:In this method, the given number is subtracted by 1, 3, 5, 7,… at every step till you get zero at the end. The number of steps in the solution is the required square root.

Answer:
1436.03 m³
Step-by-step explanation:
The formula of volume of sphere
[tex] = \frac{4}{3} \pi {r}^{3} [/tex]
The volume of the sphere
[tex] = \frac{4}{3} \times 3.14 \times {(14 \div 2)}^{3} [/tex]
[tex] = \frac{4}{3} \times 3.14 \times {7}^{3} [/tex]
[tex] = \frac{4308.08}{3} [/tex]
[tex] = 1436.0266667...[/tex]
= 1436.03 m³ (rounded to the nearest hundredth)

Step-by-step explanation:
F(x) = 2x + 3, Find the value of f(4)
Answer:
f(X)=2x+3
Step-by-step explanation:
f(4) = 2*4 + 3
= 8 + 3
= 11
Answer and Step-by-step explanation:
For this function, we need to plug in 4 for x to find out what the value of f(x) is when x is equal to 4.
f(4) = 2(4) + 3
= 8 + 3
= 11
The answer is 11, when the value is f(4).

How many teams of at least 5 students and at most 7 students can be chosen from 15 students?
5 Students = 3 Teams
7 Students = 2 Teams
To find out the answer we can use the following equation
[tex]\frac{Total}{Students} \\\\\frac{15}{5} = 3 \\\frac{15}{7} = 2.14... \\[/tex]
If you run into a decimal number, like we did when we had a team of 7, you can just round down!
Answer:
3
Step-by-step explanation:
least students= 5
maximum students = 7
total number of students = 15
no: of grps if 5 students per grp = 15/5 = 3
no: of grps if 7 students per grp = 15/7 = 2.14 ~ 2
However, if they ask us how many teams in final we can say 3 as it is the maximum number of groups that can be formed b a grp of 15 students ... if we make 7 students per grp... one would be left out .

Anna is 9 years old, and this year she received $10 from her aunt on her birthday. Her aunt has told
her that she will send $10 every birthday from now on. Which function best describes how much
money, M, Anna will have received from her aunt, in total, given how many years, y, have passed
since her 9th birthday?
O M(y) = 10y
OM(y) = 10y + 10
O M(y) = 10y - 10
M(y) = y + 10

please help me with this question
Answer:
y = -2x + 4
Step-by-step explanation:
To write an equation in slope-intercept form, y = mx + b, we need to find the slope (m) and the y-intercept (b).
✔️Slope (m) using two pairs of values, (0, 4) and (1, 2):
Slope (m) = change in y/change in x
m = (2 - 4)/(1 - 0) = -2/1
m = -2
✔️y-intercept is the value of y when x = 0. Therefore, fromm the table, when x = 0, y = 4.
y-intercept (b) = 4
✅Write the equation by substituting m = -2 and b = 4 into y = mx + b:
Thus,
y = -2x + 4

Answer:
the perimeter is 30ft
Step-by-step explanation:
a square + b square = c square
so first we find your missing side
this is how we solve for that:
a square + 12 squared = 13 squared
a squared + 144 = 169
now we do 169 - 144 = 25
now to find the missing side it is 25 square root which is 5
now that we have found the missing side lengths let's find the perimeter which is: 5 + 12 + 13 = 30 ft
I hope this helped!
