Answer:
-3(r-2)/2
Step-by-step explanation:
r/ 2 − 2 r + 6 − 3
r /2 − 2 r⋅ 2/ 2+ 6 − 3
r/ 2 + − 2r ⋅ 2/ 2 + 6 − 3
r − 2 r ⋅ 2 /2 + 6 ⋅ 2/ 2 + − 3 ⋅ 2/ 2
r − 2 r ⋅2 + 6⋅ 2 − 3 ⋅ 2 /2
r − 4 r + 12 − 6 /2
−3 ( r − 2 ) /2

Part A: Find the value of c that will result in a perfect square trinomial.
x2 + 18x + c = 25 + c
Answer:
c=81
Step-by-step explanation:
Take half of b: 18/2=9
Square the result: 9²=81
This is your value of c that will result in a perfect square trinomial, which is c=81. If you were to keep going, you would do the following:
x²+18x+81=25+81
x²+18x+81=106
(x+9)^2=106 <-- Final simplification

COMPOUND INTEREST:
You recently found out that your great-aunt passed away. Your aunt had decided to leave you an inheritance of 2,800,000, however, the will stipulates that this inheritance must remain in an investment account for the next ten years, with daily compound interest at a rate of 20% in exchange for taking care of your 34 cats. you will not be able to access this money until after this ten year period.
CAN SOMEONE HELP ME PLEASE
Answer:
You will have $17,336,862 by the end of the ten years
Step-by-step explanation:
The equation for compound interest is the amount(1+rate)^time
fill out the equation for 2,800,000(1.2)^10
2,800,000(6.19173642)
17336862

Mrs. Delgado purchased notebooks at 2 for $5 and pens
at $2 per package. She spent $19 for a total of 8 items.
How many notebooks and pens did she buy?
Answer:
Mrs. Delgado purchased 6 notebooks and 2 packages of pens.
Step-by-step explanation:
Given that Mrs. Delgado purchased notebooks at 2 for $ 5 and pens at $ 2 per package, and she spent $ 19 for a total of 8 items, to determine how many notebooks and pens did she buy the following calculation must be performed:
5/2 = 2.5
8 x 2.5 + 0 x 2 = 20
6 x 2.5 + 2 x 2 = 19
Therefore, Mrs. Delgado purchased 6 notebooks and 2 packages of pens.

Factoring
Square root Property
Completing the square
Quadratic Formula
A. 3x^2-192=0
Method:
Why:
B. x^2-x-6=0
Method:
Why:
C. x^-6x-7=0
Method:
Why:
D. x^2-17x-7=0
Method:
Why:
A. square root property
[tex]3x^2-192=0\\x^2-66=0\\x^2=66\\x= -\sqrt{66} or \sqrt{66}[/tex]
it has one value with x which is x^2 and it cn be easily solved without having to factorise, quadratic formula cant be used as it need ax^2+bx+c=0 format
B. factorising
[tex]x^2-x-6=0\\x^2+2x-3x-6=0\\(x+2)(x-3)=0\\x+2=0 and x-3=0\\x= -2 \\x= 3[/tex]
i just felt like this was easier to factorise than the other 2 options left
C. Completing the square
[tex]x^2-6x-7=0\\(x-3)^2=0\\x= -1\\x= 7[/tex]
same reason personal preference
D- Quadratic
[tex]x^2-17x-7=0\\x=\frac{-(-17)+\sqrt{(-17)^2-4(1)(-7)} }{2(1)} \\x=\frac{-(-17)-\sqrt{(-17)^2-4(1)(-7)} }{2(1)}\\x=17.4\\x=-0.402[/tex]
the 17 kinda threw me off and i didnt wanna get on factorising or doing completing the square so quadratic formal
For a National Junior Honor Society Induction Celebration, Ahmed is renting tables and chairs. He wants to have only tables for 4 and tables for 2. The total number of people that can be seated in the school cafeteria with these tables is 80. Describe some possible combinations (at least 2) of 4-seat tables and 2-seat tables that will seat 80 customers. Explain how you found them (you can show the equations; using numbers instead of words).
There are different combinations you can do.... for example
10 tables of 4 and 20 tables of 6
or
25 tables of 4 and 10 tables of 6
so Im not sure which :/ but the equation would be:
10x+20y=160
or
25x+10y=160
there are different combinations of the two so im not sure T_T

Find the area of the triangle.
Answer:
66cm²
Step-by-step explanation:
The figure shown is actually a parallelogram
The area of a parallelogram can easily be calculated by multiplying the base length by the height
For this parallelogram the height given is 6 cm and the base length given is 11cm
so area = 6 * 11
6 * 11 = 66
hence the area of the parallelogram is 66cm²

Step-by-step explanation:
t=4s+2 complex tablet
Answer:
Value of t = 2 when value of s = 0
Value of t = 6 when value of s = 1
Value of t = 10 when value of s = 2
Value of t = 14 when value of s = 3
Step-by-step explanation:
Given Equation:
t = 4s + 2
Complete the table if values of s are as follows;
s = 0
s = 1
s = 2
s = 3
Computation:
t = 4s + 2
By putting s = 0
So,
t = 4s + 2
t = 4(0) + 2
t = 0 + 2
Value of t = 2 when value of s = 0
By putting s = 1
So,
t = 4s + 2
t = 4(1) + 2
t = 4 + 2
Value of t = 6 when value of s = 1
By putting s = 2
So,
t = 4s + 2
t = 4(2) + 2
t = 8 + 2
Value of t = 10 when value of s = 2
By putting s = 3
So,
t = 4s + 2
t = 4(3) + 2
t = 12 + 2
Value of t = 14 when value of s = 3

Answer:
the question is uncompltre
Step-by-step explanation:
Which graph represents the function f(x) = 4|x|?
Which graph represents the function f(x) = 4|x|?
It looks like a "V" going straight up from 0, and hits both 4 and -4 y while going up perfectly
The graph opens upward, and it has a vertex of (0,0)
What is vertex?The vertex of an equation is the minimum or the maximum point on the graph of the equation
The equation of the graph is given as:
[tex]f(x) = 4|x|[/tex]
The above equation represents an absolute value function
An absolute value function is represented as:
[tex]f(x) = a|x -h| + k[/tex]
So, by comparison, we have:
[tex]a = 4[/tex]
[tex]h = 0[/tex]
[tex]k = 0[/tex]
This means that the graph opens upward, and it has a vertex of (0,0)
See attachment for the graph of [tex]f(x) = 4|x|[/tex]

m<9 = 83
m<5 = 97
m<7 = 83
m<16 = 97
Step-by-step explanation:
m<3 = m<2 because of vertical angles
m<10 = m<2 because of corresponding angles
m<9 + 97 = 180
m<9 = 83
m<5 + 83 = 180
m<5 = 97
m<7 = m<6 because of vertical angles
m<16 = m<5 because of alternate exterior angles.
